Functional brain activation studies described the presence of separate cortical areas responsible for central processing of peripheral vestibular information and reported their activation and interactions with other sensory modalities and the changes of this network associated to strategic peripheral or central vestibular lesions. It is already known that cortical changes induced by acute unila...

This study examines response differentiation in the sympathetically innervated skin conductance response (SCR). Differentiation in such systems has been ascribed to cortical inhibitory control over subcortical autonomic centers. Developmental study of such differentiation thus provides information on cortical development and the maturation of cortical control over subcortical centers. Previous ...

Previous experimental studies of both cortical barrel and thalamic barreloid neuron responses in rodent somatosensory cortex have indicated an active role for barrel circuitry in processing thalamic signals. Previous modeling studies of the same system have suggested that a major function of the barrel circuit is to render the response magnitude of barrel neurons particularly sensitive to the t...

The cortical representation of the sensory environment is continuously modified by experience. Changes in spatial (receptive field) and temporal response properties of cortical neurons underlie many forms of natural learning. The scale and direction of these changes appear to be determined by specific features of the behavioral tasks that evoke cortical plasticity. The neural mechanisms respons...

objective: implants are being used in orthodontics as a reliable mode of anchorage. among other factors, the cortical bone thickness plays a major role in determining the stability of these implants. the objective of this study was to study the relationship of various arch forms and the cortical bone thickness and to determine if the cortical bone thickness varies between various arch forms. th...

Background: Following peripheral nerve lesion, the adult somatosensory system showedcortical reorganizational abilities. Previous studies identified the digits' somatotopy map changes and somatosensory cortical plasticity in response to the Carpal Tunnel Syndrome (CTS) that affected the dominant hand only. Objective: Answering the remained question is that what the extent of the cortical plasti...

Understanding both the organization of the human cortex and its relation to the performance of distinct functions is fundamental in neuroscience. The primary sensory cortices display topographic organization, whereby receptive fields follow a characteristic pattern, from tonotopy to retinotopy to somatotopy [1]. GABAergic signaling is vital to the maintenance of cortical receptive fields [2]; h...
