Abstract:
Horizontally-oriented intracortical connections have been proposed to serve as a substrate for plastic reorganizations of adult motor cortex. N-methyl-D-aspartate (NMDA) receptor-dependent long-term potentiation (LTP) of synaptic efficacy is a candidate mechanism of these reorganizations in mammalian species ranging from rats to humans. The acquisition of a motor skill is accompanied by increased strength of synaptic connections within adult rat primary motor cortex, most likely due to LTP-like mechanisms.

01:35Long-term Potentiation
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

01:01Neuroplasticity
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.
