Critical period for inhibitory plasticity in rodent binocular V1.
Postnatal cortical circuit development is characterized by windows of heightened plasticity that contribute to the acquisition of mature connectivity and function. What drives the transition between different critical plasticity windows is not known. Here we show that a switch in sign of inhibitory plasticity correlates with the reported transition between the precritical period (pre-CP) and th...
متن کاملExcitatory-inhibitory balance and critical period plasticity in developing visual cortex.
Neuronal circuits are shaped by their activity during ‘‘critical’’ or ‘‘sensitive periods’’ in development. Initially spontaneous, then early sensory-evoked patterns of action potentials, are required to sculpt the remarkably complex connectivity found in the adult brain, which then loses this extraordinary level of plasticity. Whether it is the targeting of individual axons or the acquisition ...
متن کاملNeuronal Plasticity: Beyond the Critical Period
Neuronal plasticity in the brain is greatly enhanced during critical periods early in life and was long thought to be rather limited thereafter. Studies in primary sensory areas of the neocortex have revealed a substantial degree of plasticity in the mature brain, too. Often, plasticity in the adult neocortex lies dormant but can be reactivated by modifications of sensory input or sensory-motor...
متن کاملThalamocortical Inputs Show Post-Critical-Period Plasticity
Experience-dependent plasticity in the adult brain has clinical potential for functional rehabilitation following central and peripheral nerve injuries. Here, plasticity induced by unilateral infraorbital (IO) nerve resection in 4-week-old rats was mapped using MRI and synaptic mechanisms were elucidated by slice electrophysiology. Functional MRI demonstrates a cortical potentiation compared to...
متن کاملA New Critical Period for Sensory Map Plasticity
The development of neural circuits is influenced by sensory experience during restricted critical periods early in life. A novel critical period is demonstrated for plasticity of the whisker map in layer 2/3 of rat primary somatosensory cortex. Sensory experience during this period guides initial formation of whisker receptive fields.
