This chapter examines whether there are morphological and physiological changes in the IMHV associated with imprinting. When chicks were trained by exposure to a rotating red box, changes were detected in neuronal activity in the IMHV. Changes in the structure of synapses in the IMHV were studied in chicks trained by exposing them to a red box or to a flashing horizontal bar rotating upwards. Synaptic structures were modified by training regardless of the stimuli used. In both cases, training was associated with increased length of the post-synaptic density of synapses on dendritic spines. Synapses in the left IMHV were affected; no significant changes were observed in the right IMHV.

Keywords:   IMHV, imprinting process, morphological change, physiological change
