1.   Elevated muscarinic receptor seemed therefore to be associated with the early phases of memory formation.

2.   If one can discover which protein is missing, then one has a clue to its necessary role in memory formation.

3.   Controlling the flow of impulses across the synapse is a protein called the NMDA receptor, which acts as a switch for memory formation.

4.   He proceeded to work out many biochemical changes that accompany memory formation, which have proved true on creatures from slugs to people.

5.   He worked first to record the activity of nerve cells in the hippocampus, the seat of memory formation, but decided he needed a simpler system.

6.   The animals performed better than normal mice in six different tests, a strong indication that the altered gene is indeed involved in learning and memory formation.

7.   The rationale is that emotion is a strong component in memory formation, and that people who suffer traumatic experiences develop especially overwhelming memories of unpleasant events.

8.   When people are under stress, wounds tend to heal more slowly, latent viruses like herpes erupt and brain cells involved in memory formation die off.

9.   It seems strange that a natural substance in the brain would impair memory formation.

10.   They also describe experiments that show how it impairs short-term memory formation by sticking to some of the same brain structures as THC, the active ingredient in marijuana.
