Thinning of the cerebral cortex in aging.

Cerebral Cortex, 2004
The thickness of the cerebral cortex was measured in 106 non-demented participants ranging in age from 18 to 93 years. For each participant, multiple acquisitions of structural T1-weighted magnetic resonance imaging (MRI) scans were averaged to yield ...

A Flexible‐Substrate 5‐µm‐Diameter Needle Electrode: Minimizing Neuronal Death and Enabling Year‐Long Neural Recording

Advanced Materials Interfaces, EarlyView.
An electrophysiological recording technology that uses a 5‐µm‐diameter microneedle electrode device is presented. Due to the remarkable small dimension of the microneedle, the electrode provides minimal invasive neural recording in a mouse brain and enables long‐term recording exceeding the year‐long duration.

1p36 deletion syndrome: Review and mapping with further characterization of the phenotype, a new cohort of 86 patients

American Journal of Medical Genetics Part A, Volume 191, Issue 2, Page 445-458, February 2023., 2023
Abstract Chromosome 1p36 deletion syndrome (1p36DS) is one of the most common terminal deletion syndromes (incidence between 1/5000 and 1/10,000 live births in the American population), due to a heterozygous deletion of part of the short arm of chromosome 1.

The Distribution of MAP-2 Phosphorylation in Cerebral Cortex of Long-Tailed Monkey Fetuses (Macaca fascicularis) in the Last Trimester of Gestation

Indonesian Journal of Biotechnology, 2010
Memories are storage in cholinoceptive cells, the cells which are enriched with microtubule-associated protein 2 (MAP-2) that localized in the neuronal dendrite and the cell bodies.

Selective vulnerability to kainate-induced oxidative damage in different rat brain regions [PDF]

Journal of Applied Toxicology 21(5): 403-407 (2001), 2007
Some markers of oxidative injury were measured in different rat brain areas (hippocampus, cerebral cortex, striatum, hypothalamus, amygdala/piriform cortex and cerebellum) after the systemic administration of an excitotoxic dose of kainic acid (KA, 9 mg kg(-1) i.p.) at two different sampling times (24 and 48 h).

Extracellular glutamate accumulates only in final, ischemic stage of progressive epidural mass lesion in cats [PDF]

, 2001
Epidural mass lesions may cause ischemia due to progressive intracranial hypertension. In order to 1) investigate the impact of intracranial pressure (ICP) on accumulation of neuroactive substances, and 2) test the significance of neurochemical ...

Assessing the Safety Margin for Micromotion‐Induced Strain at Electrode–Tissue Interface: A Finite Element Analysis via COMSOL

Advanced Materials Interfaces, EarlyView.
Brain movement significantly impacts the biocompatibility of neural probes due to continuous strain on neural tissue. This study examines strain profiles across various brain models and movement types, challenging the 5% damage threshold at the electrode–tissue interface.

Further expansion and confirmation of phenotype in rare loss of YWHAE gene distinct from Miller–Dieker syndrome

American Journal of Medical Genetics Part A, Volume 191, Issue 2, Page 526-539, February 2023., 2023
Abstract Deletion of 17p13.3 has varying degrees of severity on brain development based on precise location and size of the deletion. The most severe phenotype is Miller–Dieker syndrome (MDS) which is characterized by lissencephaly, dysmorphic facial features, growth failure, developmental disability, and often early death.
