Rapid fluctuations in rat barrel cortex plasticity.
Neuronal populations in the sensory cortex exhibit fluctuations in excitability, and the present experiments tested the hypothesis that these variations coincide with peaks and troughs in cortical modifiability. The activity of multiunit neuronal clusters under light urethane anesthesia was recorded through 100-microelectrode arrays implanted in the infragranular layers of rat barrel cortex. Sp...
متن کاملModulatory Effects of Memantine on Neuronal Response Properties in Rat Barrel Cortex
Introduction: Memantine as N-Methyl-D-aspartic acid (NMDA) receptor antagonist is used in some neurological disorders. It has been reported that memantine has modulatory effects on the somatosensory information processing in healthy subjects. This study investigated the effect of memantine on electrophysiological properties of barrel cortex neurons in male rats. Methods: Single unit recording ...
متن کاملEffect of Norepinephrine depletion on induction of experience dependent plasticity in male rat barrel cortex
Introduction: Barrel cortex of rats is a part of somatosensory cortex, which receives information from facial whiskers. Vibrisectomy by sensory deprivation leads to some changes in the barrel cortex, which have been known as experience dependent plasticity. On the other hand, Norepinephrine (NE) and locus coeruleus, which is the main source of NE, influenced response properties of cortical bar...
متن کاملEffects of Dimethyl Sulfoxide on Neuronal Response Characteristics in Deep Layers of Rat Barrel Cortex
Introduction: Dimethyl sulfoxide (DMSO) is a chemical often used as a solvent for waterinsoluble drugs. In this study, we evaluated the effect of intracerebroventricular (ICV) administration of DMSO on neural response characteristics (in 1200–1500 μm depth) of the rat barrel cortex. Methods: DMSO solution was prepared in 10% v/v concentration and injected into the later...
متن کاملLong-Term Synaptic Plasticity in Rat Barrel Cortex.
Rats generate sweeping whisker movements in order to explore their environments and identify objects. In somatosensory pathways, neuronal activity is modulated by the frequency of whisker vibration. However, the potential role of rhythmic neuronal activity in the cerebral processing of sensory signals and its mechanism remain unclear. Here, we showed that rhythmic vibrissal stimulation with sho...
