Why Is Metaplasticity Important?

IMPORTANCE OF METAPLASTICITY
Because these synapses are strengthened, they become more likely to drive postsynaptic firing of action potentials and to potentiate again with subsequent neural activity. These synapses would eventually reach a point of saturation if their ability to potentiate were left unchecked.

What is metaplasticity in neuroscience?

Metaplasticity refers to neural changes that are induced by activity at one point in time and that persist and affect subsequently induced LTP or LTD. The activation of NMDA (N-methyl-D-aspartate) receptors can cause a persistent reduction in LTP induction and an enhancement of LTD.

Can synapses that are potentiated be depressed?

Independent stimulation of two afferent pathways has revealed that neighbouring synapses can be independently potentiated or depressed. This property of 'input specificity‚ is an important characteristic of Hebbian LTP and LTD4,23 (see figure 1).
