Effect 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 کاملExperience-dependent plasticity of neurovascularization.
Experience powerfully shapes structural and functional organization of neurons during development and in adulthood. Recent experiments in the mouse primary somatosensory cortex now suggest that experience is also a critical factor in shaping neurovasculature and promoting angiogenesis. These results support the universality of brain plasticity and show that all structural cellular components in...
متن کاملDynamic synaptic modification threshold: computational model of experience-dependent plasticity in adult rat barrel cortex.
Previous electrophysiological experiments have documented the response of neurons in the adult rat somatic sensory ("barrel") cortex to whisker movement after normal experience and after periods of experience with all but two whiskers trimmed close to the face (whisker "pairing"). To better understand how the barrel cortex adapts to changes in the flow of sensory activity, we have developed a c...

متن کاملExperience-dependent structural plasticity in the cortex.
Synapses are the fundamental units of neuronal circuits. Synaptic plasticity can occur through changes in synaptic strength, as well as through the addition/removal of synapses. Two-photon microscopy in combination with fluorescence labeling offers a powerful tool to peek into the living brain and follow structural reorganization at individual synapses. Time-lapse imaging depicts a dynamic pict...
