Proteins necessary for brain development found to be critical for long-term memory

... 24 hours later the snails -- which normally would remember the events of the previous day -- exhibited no memory of the shocks. Carew and colleagues went on to show that, when the actions of the growth factors were prevented, long-term enhancement of the connections between the brain cells in the reflex cir...
