From later studies evidence has emerged, supporting the view that memories are represented as enduring changes in the functional circuitry of the brain and that synaptic contacts between neurons serve as the pliable substrate for “memory traces”.

In 1973 Bliss and his coworkers discovered that brief high-frequency electrical stimulation of perforent pathway can enhance synaptic transmission for days even weeks in the rabbit hippocampus in vivo (Bliss and Lomo, 1973; Bliss and Gardner-Medwin, 1973). This long lasting form of synaptic plasticity is known as long-term potentiation or LTP. [...] LTP is induced by correlated pre- and postsynaptic activity i.e. it is Hebbian and exhibits several basic properties of learning and memory (Bliss and collingridge, 1993; Matthies et al., 1989, 1990; Teyler et al., 1984).

In recent years, an impressive research effort has been devoted to understand the cellular and molecular mechanisms of various forms of synaptic plasticity, particularly LTP in the hippocampus.

In the years since the publication of Hebb’s book, a growing body of evidence has emerged supporting the view that memories are represented as enduring changes in the functional circuitry of the brain and that synaptic contacts between neurons serve as the pliable substrate for “memory traces.” Perhaps most important in this regard was the discovery by Bliss, Gardner-Medwin, and Lomo in 1973 of a long-lasting increase in synaptic efficacy following electrical stimulation of the rabbit hippocampus (Bliss & Gardner-Medwin, 1973; Bliss & Lomo, 1973).

form of long-term synaptic plasticity, known as long-term potentiation or LTP, is induced by correlated pre- and postsynaptic activity (i.e., it is Hebbian) and exhibits several properties typical of learning and memory (for reviews see Bliss & Collingridge, 1993, and Teyler & DiScenna, 1984).

In recent years, an impressive research effort has been devoted to understanding the cellular and molecular mechanisms of various forms of synaptic plasticity, particularly LTP in the hippocampus and LTD in the cerebellum.
