Retinotopic activation in response to subjective contours in primary visual cortex. [PDF]

open access: yes, 2008
Objects in our visual environment are arranged in depth and hence there is a considerable amount of overlap and occlusion in the image they generate on the retina.

Morphology and histology of the thymus gland in dromedary camel with particular reference to thymic Hassall's corpuscles [PDF]

open access: yesIraqi Journal of Veterinary Sciences
The thymus gland is the primary lymphoid organ that undergoes postnatal growth followed by gradual atrophies and functional decline with age progress.

Integrative functions of the retrosplenial cortex in rats: anatomy, connectomics, and cellular electrophysiology

open access: yesАнналы клинической и экспериментальной неврологии, 2019
Current review is focused on the integrative functions of the retrosplenial cortex, which neurons are largely involved in spatial orientation and ambulation of an organism.

Correction of distortion in flattened representations of the cortical surface allows prediction of V1-V3 functional organization from anatomy. [PDF]

open access: yesPLoS Computational Biology, 2014
Several domains of neuroscience offer map-like models that link location on the cortical surface to properties of sensory representation. Within cortical visual areas V1, V2, and V3, algebraic transformations can relate position in the visual field to ...

Role of right posterior parietal cortex in maintaining attention to spatial locations over time [PDF]

open access: yes, 2009
Recent models of human posterior parietal cortex (PPC) have variously emphasized its role in spatial perception, visuomotor control or directing attention. However, neuroimaging and lesion studies also suggest that the right PPC might play a special role

In And Out Of the Loop: External and Internal Modulation Of The Olivo-Cerebellar Loop

open access: yesFrontiers in Neural Circuits, 2013
Cerebellar anatomy is known for its crystal like structure, where neurons and connections are precisely and repeatedly organized with minor variations across the Cerebellar Cortex.

Studying the Role of Human Parietal Cortex in Visuospatial Attention with Concurrent TMS-fMRI [PDF]

open access: yes, 2010
Combining transcranial magnetic stimulation (TMS) with concurrent functional magnetic resonance imaging (fMRI) allows study of how local brain stimulation may causally affect activity in remote brain regions.

Primary visual cortex neurons that contribute to resolve the aperture problem [PDF]

open access: yes, 2006
It is traditional to believe that neurons in primary visual cortex are sensitive only or principally to stimulation within a spatially restricted receptive field (classical receptive field).

Cortical thickness, gyrification and sulcal depth in trigeminal neuralgia

open access: yesScientific Reports, 2021
Neuroimaging studies have documented brain structural alterations induced by chronic pain, particularly in gray matter volume. However, the effects of trigeminal neuralgia (TN), a severe paroxysmal pain disorder, on cortical morphology are not yet known.
