The formation and maintenance of memories is one of the most intriguing functions of the brain. The human brain has the remarkable ability to store and retrieve past experiences for years and in some instances decades. Of late, extensive effort has been put into reducing the process of learning and memory to the cellular and molecular level [see ref. 1]. The underlying logic is that if we can understand how an individual neuron remembers we might then extrapolate this function to groups of neurons residing in areas of the brain involved in memory formation and storage. One such area, residing in the medial temporal lobe, is called the hippocampus. This structure is especially important for explicit or declarative memory—the recall of information pertaining to people or places [2]. The process of protein synthesis is a critical event in the encoding of long-term (explicit) memory. Thus, a great deal of research emphasis has been placed on the molecular basis of this experience-driven protein synthesis in the hope that it will elucidate the foundations of memory. The principal loci of cell-cell communication in the brain are synapses. Since synaptic transmission encodes information in the brain, the engram for memory may lie in the ability of the synapse to use stable modifications to remember its excitatory history. This form of synaptic plasticity was postulated in 1949 by Hebb [3], and was first described experimentally in the early 1970s as a long-lasting increase in synaptic strength following robust synaptic activity [4, 5]. The long-lasting potentiation (now called long-term potentiation or LTP) thatBliss and colleagues described in the hippocampus has become integral to our present theories for how memories are encoded [6, 7]. Although much of the following discussion centers on LTP, it is important to note that synaptic plasticity is a bidirectional process and that a synaptic weakening or long-term depression (LTD) is likely to play a role in memory as well [8, 9].
