Postnatal Changes of Conduction Velocity of the Fibers in and out of the Mouse Barrel Cortex
There are some conflicts about constancy of conduction velocity (CV) in a given tract of nervous system. By recording excitatory postsynaptic currents (EPSC) in layer IV of the somatosensory cortex we tried to clear changes in CV of thalamocortical tract of mice aged 3 to 50 days old. Field potentials and EPSC were recorded in the layer IV by stimulation of ventrobasal nucleus of thalamus (VB) ...
متن کاملBOLD fMRI of the mouse barrel cortex
Introduction: Understanding and identifying the neuronal networks of the cerebral cortex, their temporal properties, their development and plasticity are the focus of many functional imaging studies both in humans and rodents (1). In the mouse, a noninvasive method to study functionally the neural network of the barrel cortex would open the possibility to investigate the neurophysiological mech...
متن کاملMouse barrel cortex viewed as Dirichlet domains.
Barrels are patterned groups of neurons in rodent somatosensory cortex that correspond one to one with the animal's facial whiskers. Dirichlet domains are a class of convex polygon found frequently in nature, often arising by nucleation from center points. Analytic and graphical methods were devised to verify the hypothesis that Dirichlet domains accurately describe the adult barrel fields of n...
متن کاملBarrel cortex function
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 few thousand neurons. The high degree of c...
متن کاملInterdigitated Paralemniscal and Lemniscal Pathways in the Mouse Barrel Cortex
Primary sensory cortical areas receive information through multiple thalamic channels. In the rodent whisker system, lemniscal and paralemniscal thalamocortical projections, from the ventral posteromedial nucleus (VPM) and posterior medial nucleus (POm) respectively, carry distinct types of sensory information to cortex. Little is known about how these separate streams of activity are parsed an...
