Effects of visual deprivation on synaptic plasticity of visual cortex
TBS (Theta Burst Stimulation) and PBs (Primed Bursts) are among effective tetanic stimulations for induction of LTP in hippocampus. Recent studies have indicated that TBS is effective in LTP induction in layer III synapses of neocortex, only if applied to layer IV. However, the possibility of neocortical LTP induction using PBs, has not yet been investigated. Sensory deprivation greatly influ...
متن کاملInvolvement of voltage-dependent calcium channels in synaptic plasticity of the rat visual cortex
In this study, involvement ofvoltage-dependent calcium channels in LTP of responses of rat visual cortex slices was analyzed. Field potentials including EPSP1 and EPSP2 from layers II/III were recorded through stimulation of layer IV. Whereas nifedipine, a L-type calcium channel blocker (L-VDCC), did not considerably affect the LTP of responses, but Ni2+, a relatively selective blocker of T-typ...

متن کاملTheory of Synaptic Plasticity in Visual Cortex
A short account is given of the BCM theory of synaptic plasticity: assumptions, consequences , comparison with experiment and statistical properties. In addition a framework for comparison with other theoretical ideas is presented.
متن کاملExperience-Dependent Plasticity in Adult Visual Cortex
Experience-dependent plasticity is a prominent feature of the mammalian visual cortex. Although such neural changes are most evident during development, adult cortical circuits can be modified by a variety of manipulations, such as perceptual learning and visual deprivation. Elucidating the underlying mechanisms at the cellular and synaptic levels is an essential step in understanding neural pl...
