CREB and the formation of long-term memory
Current Opinion in Neurobiology
|April 1, 1996
Summary
Cyclic AMP response element binding protein (CREB) is crucial for long-term memory formation across species. Modulating CREB activity directly impacts memory consolidation, supporting its role in the short-term to long-term memory transition.
Area of Science:
- Neuroscience
- Molecular Biology
- Genetics
Background:
- Cyclic AMP response element binding protein (CREB)-responsive transcription is vital for long-term memory.
- CREB's role has been observed in diverse organisms like Drosophila, Aplysia, and mice.
Purpose of the Study:
- To investigate the pivotal role of CREB in the transition from short-term to long-term memory.
- To understand how CREB activity influences memory formation processes.
Main Methods:
- Utilizing agents that modulate CREB activity in model organisms.
- Observing the effects of CREB disruption and enhancement on memory formation.
Main Results:
- Disrupting CREB activity specifically blocks long-term memory formation.
- Increasing CREB amount or activity accelerates long-term memory formation.
Conclusions:
- CREB is a key molecular switch in the transition from short-term, protein synthesis-independent memory to long-term, protein synthesis-dependent memory.
- CREB-mediated transcription is essential for the consolidation of long-term memories.
