Abstract:
Based on studies of the molecular and cellular cascades that occur during memory consolidation for a one-trial passive-avoidance learning task in the young chick, I review the evidence that memory is encoded in permanent changes in synaptic connectivity ina specific brain region, the Hebb hypothesis. I conclude that despite the fact that such a cascade occurs, culminating in the synthesis of cell-adhesion molecules that are involved in synaptic remodelling, synaptic events are not in themselves sufficient to account for the phenomena of memory. Both whole brain (neuromodulator) and whole body (hormonal) processes are engaged.Memories are labile, disarticulated and stored in a distributed manner; how the mind/brain recreates coherent memories from this pattern is a mystery.

Long-Term Memory
Long-term memory can be categorized into two primary types: explicit and implicit memory. Explicit memory, also known as declarative memory, involves the conscious recollection of information that we deliberately try to remember, recall, and articulate. This type of memory encompasses specific facts, events, and...
