MORPHOLOGICAL BASIS OF LEARNING AND MEMORY

[An increasing body of evidence indicates that learning and memory involve changes in the strength of the connections between neurons.

This possibility was suggested more than a centuryago, but has received strong experimental support since the 1980s. These results are reviewed in the following two entries, which focus on studies inI nvertebratemodel systems andV ertebratemodel systems respectively.]
