Monocular visual deprivation suppresses excitability in adult human visual cortex.
The adult visual cortex maintains a substantial potential for plasticity in response to a change in visual input. For instance, transcranial magnetic stimulation (TMS) studies have shown that binocular deprivation (BD) increases the cortical excitability for inducing phosphenes with TMS. Here, we employed TMS to trace plastic changes in adult visual cortex before, during, and after 48 h of mono...
متن کاملEffects 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 کاملEffects of visual deprivation on epileptic activity in mature rat visual cortex
Effects of visual deprivation on the induction of epileptiform activity were studied in layer II/III of mature rat primary visual cortex. Field potentials were evoked by stimulation of layer IV in slices from control and dark-reared (OR) rats. Picrotoxin (PTX)-induced epileptic activity was characterized by spontaneous and evoked epileptic field potentials (EFPs). The results showed that OR s...

متن کاملShort-Term Monocular Deprivation Alters GABA in the Adult Human Visual Cortex
Neuroplasticity is a fundamental property of the nervous system that is maximal early in life, within the critical period [1-3]. Resting GABAergic inhibition is necessary to trigger ocular dominance plasticity and to modulate the onset and offset of the critical period [4, 5]. GABAergic inhibition also plays a crucial role in neuroplasticity of adult animals: the balance between excitation and ...
