Forming New Short-term Memories (3)
Professor Ron Davis explains that short-term memories are formed by recruiting new synapses. It is unknown whether long-term memories are formed in the same way.
So the observation we made in terms of recruitment of new synapses into the representation of an odor â€“ this is the basis for how memories are formed. This was made for very short-term memories. The recruitment only lasted a very, very short period â€“ minutes. Now clearly we, and fruit flies, can remember for hours and even days, so this is inadequate to account for long-term memories. So long-term memories could form through the same mechanisms just through more enduring changes or there might be completely different mechanisms used for the formation of long-term memories.

Professor Ron Davis describes how memories are formed through the addition of new synapses.
Professor Ron Davis discusses how his lab observed that short term memories are formed through the recruitment of new synapses.
Professor Ron Davis explains that the gene CREB is important to memory. Blocking CREB expression, blocks short-term memory formation.
Professor Eric Kandel compares short-term memory, which involves the alteration of pre-existing proteins, and long-term memory, which involves new protein synthesis.
Professor Seth Grant explains that long-term memories are created when the synapse sends a signal to the nucleus to activate certain genes.
Learning and memory are two intimately linked cognitive processes that stem from interactions with the environment (experience).
Communication in brain cells is guided by interactions between genes and biochemicals at the synapse. These interactions can lead to the formation of new synapses.
Professor Ron Davis discusses the attributes that make the fruit fly a good model for studying memory in humans.

It is increasingly clear that the nonneuronal brain cells called glia are intricately involved in the neuronal crosstalk at synapses.
