Abstract
The intermediate and medial hyperstriatum ventrale (IMHV) of the chick brain has a central role in the recognition memory of imprinting. This learning process leads to major changes in IMHV neuronal responsiveness. Previous experiments using anatomical and biochemical techniques suggest that these changes result from a reorganisation of synapses within IMHV. The proposed experiments will detail changes in neuronal connectivity (functional coupling) between IMHV neurones during and after imprinting. Critical tests will be made of theoretical predictions concerning such coupling, and the synchronisation of neuronal activity between responsive neurones. We will also determine how the development of a chick's naive preferences for conspecifics biases the neuronal responsiveness of the IMHV memory system.
