Glia, Volume 71, Issue 2, Page 187-204, February 2023., 2023 Main Point Loss of oligodendrocyte ErbB receptor signaling leads to A1 hypomyelination, reduced PV expression and density of PV+ neurons and synapses, hypoconnectivity of inhibitory circuits and shift of the E/I balance towards excitation. Abstract For a long time, myelin was thought to be restricted to excitatory neurons, and studies on dysmyelination

A Pilot Study on the Comparison of Prefrontal Cortex Activities of Robotic Therapies on Elderly with Mild Cognitive Impairment [PDF]
arXivDemographic shifts have led to an increase in mild cognitive impairment (MCI), and this study investigates the effects of cognitive training (CT) and reminiscence therapy (RT) conducted by humans or socially assistive robots (SARs) on prefrontal cortex activation in elderly individuals with MCI, aiming to determine the most effective therapy-modality ...

Annals of Neurology, EarlyView.Objective The objective is to evaluate cognitive and behavioral progression and identify early predictors of these changes in a cohort of amyotrophic lateral sclerosis (ALS) patients. Methods A total of 161 ALS patients were tested at diagnosis (T0), and 107 were re‐tested after 1 year (T1) using cognitive/behavioral tests. All patients underwent whole‐

Glia, Volume 71, Issue 2, Page 415-430, February 2023., 2023 Main Points A subset of OPCs do not express Olig2, of which population peaks in the juvenile brain while wanes with age. Plastic changes of the brain by acute injuries or complex motor learning stop the expression of Olig2 in OPCs. Abstract Oligodendrocyte precursor cells (OPCs) are uniformly distributed in the mammalian brain; however, their function ...

ORGaNICs: A Theory of Working Memory in Brains and Machines [PDF]
arXiv, 2018 Working memory is a cognitive process that is responsible for temporarily holding and manipulating information. Most of the empirical neuroscience research on working memory has focused on measuring sustained activity in prefrontal cortex (PFC) and/or parietal cortex during simple delayed-response tasks, and most of the models of working memory have ...

Pituitary Adenylate Cyclase-Activating Polypeptide (PACAP) Signaling in The Prefrontal Cortex Modulates Cued Fear Learning, But Not Spatial Working Memory, in Female Rats [PDF]
, 2018 A genetic polymorphism within the gene encoding the pituitary adenylate cyclase- activating polypeptide (PACAP) receptor type I (PAC1R) has recently been associated with hyper-reactivity to threat-related cues in women, but not men, with post-traumatic ...

Prefrontal cortical thickness in motor neuron disease
NeuroImage: Clinical, 2018 Objective: To examine whether the distribution of prefrontal cortical thickness in patients with motor neuron disease is normal or bimodal and how it compares to the normal population.

Annals of Neurology, EarlyView.Objective The involvement of cortical inflammation in migraine, particularly migraine with aura, has been a subject of considerable interest, but has proved challenging to demonstrate. We aimed to detect and characterize signs of cortical inflammation in adults with migraine using a novel, multimodal magnetic resonance imaging (MRI) technique.
