Hebbian synapse long-term potentiation essay

ified in several laboratories, that longterm potentiation (LTP) in some parts of the mammalian hippocampus follows the Hebb rule (Kelso et al.1986; Levy rt al.1983; McNaughton et al.1978; Wigstrom and Gus tafsson, 1985; McNaughton and Morris, 1987; Brown et id.1988; see Chapter 14 in this volume). Conditioning synapses between layer IV and III neurons results in longterm potentiation (LTP) (Fig. 19. 15). This is prevented by the application of acid (APV), an NMDA receptor antagonist.

Longterm potentiation (LTP) is a persistent increase in synaptic strength following highfrequency stimulation of a chemical synapse. Studies of LTP are often carried out in slices of the hippocampus, an important organ for learning and memory.

Hebbian theory is a neuroscientific theory claiming that an increase in synaptic efficacy arises from a presynaptic cell's repeated and persistent stimulation of a postsynaptic cell.

It is an attempt to explain synaptic plasticity, the adaptation of brain neurons during the learning process. Physiological Psychology LongTerm Potentiation.
