To Establish Long-Term "Memory," Neurons Have to Synthesize New Proteins

The details of memory formation are still largely unknown. It has, however, been established that the two kinds of memory -- long term and short term -- use different mechanisms. When short-term memory is formed, certain proteins in the nerve cells (neurons) of the brain are transiently modified. To establish long-term memory, the cells have to synthesize new protein molecules. This has been shown in experiments with animals. When drugs were used to block protein synthesis, the treated animals were not able to form long-term memory. more
