Remyelination alters the pattern of myelin in the cerebral cortex

open access: yeseLife, 2020
Destruction of oligodendrocytes and myelin sheaths in cortical gray matter profoundly alters neural activity and is associated with cognitive disability in multiple sclerosis (MS).

Twofold mechanosensitivity ensures actin cortex reinforcement upon peaks in mechanical tension [PDF]

open access: yesarXiv, 2023
The actin cortex is an active biopolymer network underneath the plasma membrane at the periphery of mammalian cells. It is a major regulator of cell shape through the generation of active cortical tension. In addition, the cortex constitutes a mechanical shield that protects the cell during mechanical agitation. Cortical mechanics is tightly controlled

Neurons and circuits for odor processing in the piriform cortex [PDF]

open access: yes, 2013
Increased understanding of the early stages of olfaction has lead to a renewed interest in the higher brain regions responsible for forming unified ‘odor images’ from the chemical components detected by the nose.

CNS Macrophages Control Neurovascular Development via CD95L

open access: yesCell Reports, 2017
The development of neurons and vessels shares striking anatomical and molecular features, and it is presumably orchestrated by an overlapping repertoire of extracellular signals.

Improving a probabilistic cytoarchitectonic atlas of auditory cortex using a novel method for inter-individual alignment

open access: yeseLife, 2020
The human superior temporal plane, the site of the auditory cortex, displays high inter-individual macro-anatomical variation. This questions the validity of curvature-based alignment (CBA) methods for in vivo imaging data.

Frequency-Specific Abnormalities of Intrinsic Functional Connectivity Strength among Patients with Amyotrophic Lateral Sclerosis: A Resting-State fMRI Study

open access: yesFrontiers in Aging Neuroscience, 2017
The classical concept that amyotrophic lateral sclerosis (ALS) is a degenerative disorder characterized by the loss of upper and lower motor neurons is agreed. However, more and more studies have suggested the involvement of some extra-motor regions. The

Frontal top-down signals increase coupling of auditory low-frequency oscillations to continuous speech in human listeners [PDF]

open access: yes, 2015
Humans show a remarkable ability to understand continuous speech even under adverse listening conditions. This ability critically relies on dynamically updated predictions of incoming sensory information, but exactly how top-down predictions improve ...

Integration of somatosensory and motor-related information in the auditory system

open access: yesFrontiers in Neuroscience, 2022
An ability to integrate information provided by different sensory modalities is a fundamental feature of neurons in many brain areas. Because visual and auditory inputs often originate from the same external object, which may be located some distance ...

Emotion, decision making and the orbitofrontal cortex.

open access: yesCerebral Cortex, 2000
The somatic marker hypothesis provides a systems-level neuroanatomical and cognitive framework for decision making and the influence on it by emotion.

Dipicolinic Acid Release by Germinating Clostridium difficile Spores Occurs through a Mechanosensing Mechanism

open access: yesmSphere, 2016
Classically, dormant endospores are defined by their resistance properties, particularly their resistance to heat. Much of the heat resistance is due to the large amount of dipicolinic acid (DPA) stored within the spore core.
