Attention-dependent modulation of cortical taste circuits revealed by granger causality with signal-dependent noise [PDF]
, 2013 We show, for the first time, that in cortical areas, for example the insular, orbitofrontal, and lateral prefrontal cortex, there is signal-dependent noise in the fMRI blood-oxygen level dependent (BOLD) time series, with the variance of the noise ...

Resting State Functional Connectivity of the Rat Claustrum
Frontiers in Neuroanatomy, 2019 The claustrum is structurally connected with many cortical areas.A major hurdle standing in the way of understanding claustrum function is the difficulty in assessing the global functional connectivity (FC) of this structure.

Radial glia in the proliferative ventricular zone of the embryonic and adult turtle, Trachemys scripta elegans. [PDF]
, 2014 To better understand the role of radial glial (RG) cells in the evolution of the mammalian cerebral cortex, we investigated the role of RG cells in the dorsal cortex and dorsal ventricular ridge of the turtle, Trachemys scripta elegans.

Reduction in Phencyclidine Induced Sensorimotor Gating Deficits in the Rat Following Increased System Xc − Activity in the Medial Prefrontal Cortex [PDF]
, 2013 Rationale: Aspects of schizophrenia, including deficits in sensorimotor gating, have been linked to glutamate dysfunction and/or oxidative stress in the prefrontal cortex. System xc −, a cystine–glutamate antiporter, is a poorly understood mechanism that

Altered muscarinic and nicotinic receptor densities in cortical and subcortical brain regions in Parkinson's disease [PDF]
, 1993 Muscarinic and nicotinic cholinergic receptors and choline acetyltransferase activity were studied in postmortem brain tissue from patients with histopathologically confirmed Parkinson's disease and matched control subjects.

Progress in Neurobiology, 2013 Neocortex, the neuronal structure at the base of the remarkable cognitive skills of mammals, is a layered sheet of neuronal tissue composed of juxtaposed and interconnected columns. A cortical column is considered the basic module of cortical processing present in all cortical areas. It is believed to contain a characteristic microcircuit composed of a

Spontaneous formation of chaotic protrusions in a polymerizing active gel layer
, 2019 The actin cortex is a thin layer of actin filaments and myosin motors beneath the outer membrane of animal cells. It determines the cells' mechanical properties and forms important morphological structures.

Distribution of ELOVL4 in the Developing and Adult Mouse Brain
Frontiers in Neuroanatomy, 2017 ELOngation of Very Long chain fatty acids (ELOVL)-4 is essential for the synthesis of very long chain-fatty acids (fatty acids with chain lengths ≥ 28 carbons).

Remyelination alters the pattern of myelin in the cerebral cortex
eLife, 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).
