Lesion studies and the role of IMHV in early learning
This chapter compares the effects of lesions to a single region of the chick brain, the intermediate part of the medial hyperstriatum ventrale (IMHV), on a number of behavioural tasks and discusses their implications for the function of IMHV. The results of experiments designed to investigate the effects of brain lesions on behaviour are difficult to interpret since they do not necessarily provide unambiguous information about the localization of function within the brain. Lesion studies have contributed greatly to the knowledge of the neural basis of learning in the chick. The key to understanding the differences in the function of IMHV in the tasks in which it is involved is likely to lie in the interaction of IMHV with other brain regions, known as filial imprinting – the process by which a chick learns to form a preference for the first visually conspicuous object to which it is exposed.
