Astrocyte morphology is confined by cortical functional boundaries in mammals ranging from mice to human

open access: yeseLife, 2016
Cortical blood flow can be modulated by local activity across a range of species; from barrel-specific blood flow in the rodent somatosensory cortex to the human cortex, where BOLD-fMRI reveals numerous functional borders.

Injuries to the Immature Optic Radiation Show Correlated Thinning of the Macular Ganglion Cell Layer

open access: yesFrontiers in Neurology, 2018
Injuries to the immature optic radiation (OR) are associated with thinning of the retinal nerve fiber layer and corresponding visual field (VF) defects.

Decline and fall:a biological, developmental, and psycholinguistic account of deliberative language processes and ageing [PDF]

open access: yes, 2011
Background: This paper reviews the role of deliberative processes in language: those language processes that require central resources, in contrast to the automatic processes of lexicalisation, word retrieval, and parsing.

Does experience provide a permissive or instructive influence on the development of direction selectivity in visual cortex?

open access: yesNeural Development, 2018
In principle, the development of sensory receptive fields in cortex could arise from experience-independent mechanisms that have been acquired through evolution, or through an online analysis of the sensory experience of the individual animal.

Attention decreases phase-amplitude coupling, enhancing stimulus discriminability in cortical area MT

open access: yesFrontiers in Neural Circuits, 2015
Local field potentials (LFPs) in cortex reflect synchronous fluctuations in the activity of local populations of neurons. The power of high frequency (>30 Hz) oscillations in LFPs is locked to the phase of low frequency (

Quantized Visual Awareness

open access: yesFrontiers in Psychology, 2013
The proposed model holds that, at its most fundamental level, visual awareness is quantized. That is to say that visual awareness arises as individual bits of awareness through the action of neural circuits with hundreds to thousands of neurons in at ...

Release from cross-orientation suppression facilitates 3D shape perception. [PDF]

open access: yesPLoS ONE, 2009
Cross-orientation suppression (COS) in striate cortex has been implicated in the efficient encoding of visual stimuli. We show that release from COS facilitates the decoding of 3-D shape.

Immunoreactivity of Vesicular Glutamate Transporter 2 Corresponds to Cytochrome Oxidase-Rich Subcompartments in the Visual Cortex of Squirrel Monkeys

open access: yesFrontiers in Neuroanatomy, 2021
Cytochrome oxidase (CO) histochemistry has been used to reveal the cytoarchitecture of the primate brain, including blobs/puffs/patches in the striate cortex (V1), and thick, thin and pale stripes in the middle layer of the secondary visual cortex (V2 ...

Exploring the physiological correlates of chronic mild traumatic brain injury symptoms

open access: yesNeuroImage: Clinical, 2016
We report on the results of a multimodal imaging study involving behavioral assessments, evoked and resting-state BOLD fMRI, and DTI in chronic mTBI subjects.

State of catecxolaminergine systems of the brain in forming of sydnocarb psychosis [PDF]

open access: yesMedičnì Perspektivi, 2014
Violations of mnestic reactions are one of substantial signs of disorders of nervous activity. On the basis of it, as a criterion of forming of experimental psychosis, in our supervisions, the state of processes of conditionally-reflex memory was studied
