Forming New Short-term Memories (2)
Professor Ron Davis describes how memories are formed through the addition of new synapses.
The importance of this observation is the fact that many of us in the past, many of us in the field of learning and memory, have thought that memories formed through the strength of synapses. For example, if we learned about an odor, we might perceive an odor and that might be represented by the activity of a certain set of synapses. After we learned about the odor, we have imagined, and there's evidence for this, that the magnitude of the synaptic activity changes. So they increase their activity. What weâ€™ve demonstrated, is this is a different type of how memories are formed, basically itâ€™s not through a change in the magnitude of synaptic activity but itâ€™s the addition of new synapses into the representation of that sensory information.

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.
Professor Ron Davis discusses how his lab observed that short term memories are formed through the recruitment of new synapses.
Professor Ron Davis discusses exciting future directions in memory research.
Professor Ron Davis explains that the gene CREB is important to memory. Blocking CREB expression, blocks short-term memory formation.
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.

It is increasingly clear that the nonneuronal brain cells called glia are intricately involved in the neuronal crosstalk at synapses.
Discs, large homolog 3 (DLG3) is a gene associated with learning and memory. DLG3 encodes synapse-associated protein 102 (SAP102).
Learning and memory are two intimately linked cognitive processes that stem from interactions with the environment (experience).
