Effects of Neonatal C-Fiber Depletion on Interaction between Neocortical Short-Term and Long-Term Plasticity
Introduction: The primary somatosensory cortex has an important role in nociceptive sensory-discriminative processing. Altered peripheral inputs produced by deafferentation or by long-term changes in levels of afferent stimulation can result in plasticity of cortex. Capsaicin-induced depletion of C-fiber afferents results in plasticity of the somatosensory system. Plasticity includes short-term...
متن کاملPresynaptic long-term plasticity
Long-term synaptic plasticity is a major cellular substrate for learning, memory, and behavioral adaptation. Although early examples of long-term synaptic plasticity described a mechanism by which postsynaptic signal transduction was potentiated, it is now apparent that there is a vast array of mechanisms for long-term synaptic plasticity that involve modifications to either or both the presyna...

متن کاملMonocular deprivation boosts long-term visual plasticity
for the deprived eye in the early and middle periods of the training stage for all subjects, performance levels were similar between the eyes in the late period (Figure B). Significant differences were observed in the early (paired t-test, P = 0.0 5) and middle (P = 0.00 ) periods, but no significant difference in the late period (P = 0.380) (Figure C). These results suggest that MD selectively...
متن کاملDynamical model of long-term synaptic plasticity.
Long-term synaptic plasticity leading to enhancement in synaptic efficacy (long-term potentiation, LTP) or decrease in synaptic efficacy (long-term depression, LTD) is widely regarded as underlying learning and memory in nervous systems. LTP and LTD at excitatory neuronal synapses are observed to be induced by precise timing of pre- and postsynaptic events. Modification of synaptic transmission...
