The effect of ibotonic acid lesion of the nucleus basalis of Meynert (NBM) on the response of cortical neurons in the rat barrel cortex
In the present study, the effect of NBM lesion on the temporal characteristics of response integration evoked by multiple whisker stimulations in the barrel cortex of rats was studied. Nucleus basalis of Meynert (NBM) projects to widespread areas of the cortex and provides the major cholinergic input (80%) to the cerebral cortex. In this study we examined the effects of NBM lesion on the respon...

متن کاملPostnatal 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 کاملThe Excitatory Neuronal Network of the C2 Barrel Column in Mouse Primary Somatosensory Cortex
Local microcircuits within neocortical columns form key determinants of sensory processing. Here, we investigate the excitatory synaptic neuronal network of an anatomically defined cortical column, the C2 barrel column of mouse primary somatosensory cortex. This cortical column is known to process tactile information related to the C2 whisker. Through multiple simultaneous whole-cell recordings...
متن کاملEffects of cortical activation on sensory responses in barrel cortex.
Neocortex network activity changes from a deactivated state during quiescence to an activated state during arousal and vigilance. In urethane-anesthetized rats, cortical activation is readily produced by either stimulating the brainstem reticular formation or by application of cholinergic agonists into the thalamus. We studied the effects of cortical activation on spontaneous activity and senso...
