The cellular foundations of learning

Lately a lot of progress has been made, enhancing our understanding of how information is stored in the brain. It has become clear that changes in the points of connection between neurons – the synapses, play a major role. Technological progress in recent years has made it possible to actually observe such changes in the living brain. These observations clearly demonstrate functional as well as structural changes in the synapses. One remaining challenge is to observe and verify these changes in animals behaving and learning in a natural or at least semi-natural environment.
