Neural Bypasses: Literature Review and Future Directions in Developing Artificial Neural Connections

Received: 16 November 2022;  Published: 22 February 2023;  doi: 10.21926/obm.neurobiol.2301158

Abstract

Reported neuro-modulation schemes in the literature are typically classified as closed-loop or open-loop. A novel group of recently developed neuro-modulation devices may be better described as a neural bypass, which attempts to transmit neural data from one location of the nervous system to another. The most common form of neural bypasses in the literature utilize EEG recordings of cortical information paired with functional electrical stimulation for effector muscle output, most commonly for assistive application [...]

Theoretical Grounds of Shared Intentionality for Neuroscience in Developing Bioengineering Systems

Received: 25 October 2022;  Published: 17 February 2023;  doi: 10.21926/obm.neurobiol.2301156

Abstract

The article discusses a definition of shared intentionality that reflects recent discoveries for inspiring further translational research in developing bioengineering systems based on human-computer interaction. The child's cognition begins through shared intentionality that occurs in child-caregiver interaction when communication via sensory cues is impossible. There needs to be more knowledge on how it appears. This article argues that shared intentionality is collaborative interactions in which participants shar [...]

Intrinsic Lexical Intentionality and the Mathematics of Homomorphism

Received: 28 August 2022;  Published: 01 February 2023;  doi: 10.21926/obm.neurobiol.2301152

Abstract

Moisl [1, 2] proposed a model of how the brain implements intrinsic intentionality with respect to lexical and sentence meaning, where 'intrinsic' is understood as 'independent of interpretation by observers external to the cognitive agent'. The discussion in both was mainly philosophical and qualitative; the present paper gives a mathematical account of the distance structure preservation that underlies the proposed mechanism of intrinsic intentionality. The three-layer autoassociative multilayer perceptron (aMLP) [...]

Transcranial Electrical Stimulation in Migraine – How Does It Work and What Can We Learn from It?

Received: 08 August 2022;  Published: 14 November 2022;  doi: 10.21926/obm.neurobiol.2204145

Abstract

Although being one of the most common neurological disorders, migraine is commonly misunderstood and misdiagnosed. Current treatments rely on pharmacological approaches, which have been shown not to be effective for all, and so alternative, non-invasive treatments are being sought. Transcranial stimulation could be a possible treatment for migraine. Transcranial electrical stimulation generally involves applying a current to the cortex via the scalp. Whilst this has previously been mostly done in clinical settings, [...]

Examining the Social Signaling and Person Perception Functions of Loneliness

Received: 07 January 2022;  Published: 19 April 2022;  doi: 10.21926/obm.neurobiol.2202119

Abstract

Loneliness is a common condition that poses substantial risks to morbidity and mortality. Cacioppo and Cacioppo’s [1] evolutionary theory of loneliness (ETL) provides that loneliness serves a social signaling function and also manifests in hypervigilance to threat, which we propose can influence person perception. In this experiment, 480 observers evaluated videotaped self-presentation messages from speakers who scored either high or low on a measure of loneliness. On the basis of ETL, we hypothesized that observer [...]

Received: 24 January 2022;  Published: 22 March 2022;  doi: 10.21926/obm.neurobiol.2201116

Abstract

Glaucomatous optic neuropathy (GON) associated with different forms of glaucoma and chronic ocular hypertension (cOHT) is characterized by progressive loss of retinal ganglion cells and their axons in the optic nerves that project to the brain to transmit visual information. The resultant thinning of the optic nerves cause loss of peripheral vision, which if not halted or slowed, can lead to irreversible blindness. Whilst the precise triggering insult(s) for the primary open angle glaucoma (POAG), the most prevalen [...]

Analysis of Migraine Pathophysiology by Magnetic Resonance Imaging

Received: 25 October 2021;  Published: 08 February 2022;  doi: 10.21926/obm.neurobiol.2201115

Abstract

Magnetic resonance imaging (MRI) has been used to investigate migraine pathophysiology because it is a non-invasive technique. The main aim of clinical imaging for patients with headaches is to exclude secondary headaches due to organic lesions. Conventional structural imaging techniques such as routine MRI demonstrate white matter lesions, changes in gray matter volume or cortical thickness, and cerebral blood flow in patients with migraine. Changes in metabolite levels are observed by magnetic resonance spectrosc [...]

Light-Activated Local Drug Delivery From Hydrogels: Potential for GBM Treatment

Received: 15 December 2020;  Published: 23 March 2021;  doi: 10.21926/obm.neurobiol.2101090

Abstract

Following post-operative treatment, the vast majority of GBMs recur, usually within 2 cm of the tumor resection margin. Since these tumors seldom metastasize outside the CNS, improved localized therapies should prove beneficial. Drug delivery systems (DDS) that allow control over drug release by an externally applied energy, such as light, have the potential of improving the results of chemotherapy. Light-activated hydrogel DDS, implanted in the operative cavity formed by tumor resection, bypasses the blood brain b [...]

In addition to the primary injury there is accumulating neurophysiological and histological evidence of dysfunction in the peripheral nerves, not related to direct damage from the primary injury, which exacerbates muscle wasting, and contributes to further functional loss and poor recovery. Among the potential contributing factors are systemic inflammation, and mo [...]

Celiac Disease and Associated Extraintestinal Manifestations, with Special Reference to Neurological Disorders

Received: 13 July 2020;  Published: 30 October 2020;  doi: 10.21926/obm.neurobiol.2004074

Abstract

Celiac disease (CD), also known as gluten-sensitive enteropathy and nontropical sprue, is one of the most important entities of the wide spectrum of gluten-related disorders (GRDs). It is well known that neurological manifestations can be present either at the onset of CD, or appear during the development of the pathology, and the neurologic findings can show a profound difference. Clinical features show significant variation, ranging from typical manifestations of gastrointestinal involvement to several extraintes [...]

A Case of Coincidental Association of Amyotrophic Lateral Sclerosis in a Patient with Celiac Disease Consuming a Gluten-Free Diet

Received: 30 June 2020;  Published: 12 October 2020;  doi: 10.21926/obm.neurobiol.2004073

Abstract

We report, for the first time, the case of amyotrophic lateral sclerosis (ALS) onset in a 54-year-old woman not following a strict gluten-free diet (GFD) for six years after the diagnosis of celiac disease (CD). The patient did not display any sign of gluten toxicity, malabsorption, or CD-related comorbidity. Previous cases reported in medical literature showed ALS-like forms secondary to gluten intolerance, with symptom remission after a strict GFD. Even after correcting dietary flaws, the clinical manifestation o [...]

Voice and Speech Disorders in Alzheimer’s Disease: A State-of-the-Art Review

Received: 29 June 2020;  Published: 08 September 2020;  doi: 10.21926/obm.neurobiol.2003072

Abstract

Alzheimer’s disease is the most common type of dementia in the world. This manuscript attempts to review the current knowledge of neurolaryngology and speech and language therapy in Alzheimer’s disease in order to distinguish it from other neurodegenerative diseases. Only a limited number of studies carried out on Alzheimer’s disease patients with speech or laryngeal disorders are found in the literature. Laryngeal (dysphonia, dysphagia, dry mucosa…) and speech symptoms (aphasic, rhythm alterations…) appear to exis [...]

Epigenetics of Sleep Disruption

Received: 27 June 2020;  Published: 08 September 2020;  doi: 10.21926/obm.neurobiol.2003071

Abstract

Sleep plays an important role in maintaining brain function, memory consolidation, hormonal balance, immune system function, growth, and repair. The physiological and psychological effects of disruptions in sleep highlight its importance in human health and wellness. Epigenetic roles are proposed in sleep, and circadian regulation, but only a limited number of studies have determined the mechanism that underlies the epigenetics of environmental factors interacting with the sleep, particularly the ones related to sl [...]

Exploring Potential Neurobiological Parallels of Restrictive Behaviour: Anorexia Nervosa and Chew and Spit (CHSP)

Received: 05 May 2020;  Published: 18 August 2020;  doi: 10.21926/obm.neurobiol.2003070

Abstract

Consensus for where along the eating disorder spectrum the pathological eating behaviour of Chew and Spit (CHSP) falls has been a point of contention in academic literature. Using the case of Mary1, a 30 year old female from Australia who has engaged in excessive restrictive behaviour, was diagnosed with anorexia nervosa (AN) and has been engaging in Chew and Spit (CHSP) behaviour for over 10 years, the current paper examines the similarities from a neurobiological perspective between restrictive behaviours (akin w [...]

Neurostimulation Approaches in the Treatment of Severe Anorexia Nervosa

Received: 04 May 2020;  Published: 07 August 2020;  doi: 10.21926/obm.neurobiol.2003069

Abstract

Psychiatry is seeking interventions that could reliably sustain weight gain and psychosomatic recovery of patients with severe anorexia nervosa (AN). Currently, patients with AN, even after receiving individually-tailored therapeutic interventions, often relapse following marginal weight restoration. Also, the evidence regarding the effectiveness of psychotropic medications in relieving and treating AN symptomology is limited. The research in the field is aiming to mitigate shortcomings associated with common pract [...]

Neonatal Hypoxic Ischemic Encephalopathy: An Updated Preclinical and Clinical Review

Received: 04 February 2020;  Published: 28 July 2020;  doi: 10.21926/obm.neurobiol.2003068

Abstract

Hypoxic-ischemic encephalopathy is a major cause of death and disability in the newborn period. Experimental models have demonstrated that brain injury in hypoxic-ischemic encephalopathy occurs in two phases: primary energy failure and secondary energy failure. In primary energy failure, there is a cessation of oxidative metabolism and irreversible neuronal injury, followed by secondary energy failure due to glutamate release, elevation of intracellular calcium, reactive oxygen species formation, apoptotic cell dea [...]

Behavioral Disorders and Celiac Disease: Coincidence or Casualty?

Received: 10 May 2020;  Published: 24 July 2020;  doi: 10.21926/obm.neurobiol.2003067

Abstract

This paper presents the case of a child diagnosed with both celiac disease and Asperger’s syndrome. The literature does not report this association to date, and the authors believe it to be a coincidence rather than a casualty.

Neurological Manifestations of the Celiac Disease in Children

Received: 07 May 2020;  Published: 17 July 2020;  doi: 10.21926/obm.neurobiol.2003066

Abstract

Gluten-related disorders (GRDs) represent a spectrum of diverse clinical manifestations triggered by the ingestion of gluten in genetically susceptible individuals. The most common and widely recognized diseases within this spectrum are celiac disease and non-celiac gluten sensitivity. The clinical manifestations are intestinal, but extraintestinal manifestations may also appear, such as neurological or psychiatric. This work will specifically review the neurological or psychiatric manifestations that are more freq [...]

Neurological Manifestations of Celiac Disease and Non-Celiac Gluten Sensitivity and the Effect of a Gluten Free Diet

Received: 17 May 2020;  Published: 10 July 2020;  doi: 10.21926/obm.neurobiol.2003065

Abstract

Celiac disease (CeD) is an immune-mediated enteropathy triggered by gluten ingestion and affects nearly 1% of the population worldwide. CeD has typically been associated with gastrointestinal symptoms such as diarrhea and abdominal pain; however, its extra-intestinal manifestations are becoming widely recognized. In particular, CeD patients may present with various neurological manifestations and oftentimes, without evidence of gastrointestinal symptoms. The pathophysiology behind these manifestations is not well k [...]

Prone Anesthesia for a Super-Super Morbidly Obese Patient Undergoing Neurosurgery: A Case Report

Received: 03 May 2020;  Published: 24 June 2020;  doi: 10.21926/obm.neurobiol.2002064

Abstract

Obesity is on the rise around the world, carrying along with it a wide range of comorbidities and complications. We report on a super-super morbidly obese 43-year-old female, with a body mass index (BMI) of 77.85 kg/m2 (173cm, 233kg), who presented for a scheduled suboccipital craniectomy with C-1 laminectomy secondary to symptoms from an Arnold-Chiari type-I malformation. Already a challenging type of surgery, due to the patient’s extreme BMI and positioning, the surgery became more difficult. There are many [...]

Synaptic Plasticity and Learning Processes: A Neuroeducation Perspective

Received: 14 April 2020;  Published: 22 June 2020;  doi: 10.21926/obm.neurobiol.2002063

Abstract

The story of each individual is essentially the story of their learning processes and relationships from the moment they were born. Indeed, the story of learning processes is merely a constant stratification of experiences based on biological and neurofunctional features that are influenced by genetic and cultural factors and subject to environmental stimuli constantly reshaping their behaviour.Neuroscientific studies conducted over the past decades have highlighted a unique feature of the human nervous system, cal [...]

Neuroprotective Strategies in Glaucoma - Translation to Clinical Trials

Received: 16 April 2020;  Published: 15 June 2020;  doi: 10.21926/obm.neurobiol.2002062

Abstract

Neuroprotection in glaucoma is any medical treatment by which decline in visual function can be slowed or prevented by supporting the health and survival of neural cells, independent of lowering of intraocular pressure (IOP). This is achieved by targeting mechanisms to inhibit or delay retinal ganglion cell death and promote cell survival pathways. Despite demonstrating promising results in preclinical trials, many neuroprotective strategies have failed to show success in subsequent clinical trials. Of the clinical [...]

Non-linear Dynamics and Chaotic Trajectories in Brain-Mind Visual Experiences during Dreams, Meditation, and Non-Ordinary Brain Activity States

Received: 30 April 2020;  Published: 11 June 2020;  doi: 10.21926/obm.neurobiol.2002061

Abstract

The present report discusses brain visual experiences in conditions of low degree of openness of the brain toward the environment, for example, while dreaming, during meditation, or in non-ordinary brain activity states such as under the effects of psychoactive substances, in the state of coma, or in other states of reduced sensory perception, among others. In the present report, for brevity, such states are referred to as brain-mind visual experiences, implying that such a visual activity is not one connected to t [...]

Dynamic Functional Connectivity Fading Analysis and Classification of Alzheimer’s Disease, Mild Cognitive Impairment and Normal Control Subjects based on Resting-State fMRI Data

Received: 29 September 2019;  Published: 01 June 2020;  doi: 10.21926/obm.neurobiol.2002059

Abstract

In this paper, motivated by the fading effect in wireless communications, where severe channel fading is related to information loss during the transmission, we evaluate and analyze the fading effect in time-varying functional connectivity of AD, MCI and NC subjects based on the resting-state fMRI data, and then apply that for AD, MCI, NC classification. We show that in some critical brain regions, compared with NC subjects, AD subjects suffer more severe and long lasting fading in the functional connectivity level [...]
