Brain lesions, acquisition, and retention
Brain lesions, acquisition, and retention
This chapter investigated whether the ‘intermediate and medial part of hyperstriatum ventrale’ (IMHV) is necessary for imprinting. The IMHV of chicks were lesioned and exposed to an imprinting stimulus. It was shown that if the IMHV is destroyed bilaterally before training, the chicks fail to develop a preference for the training object. If the region is destroyed bilaterally after training is complete, retention is severely impaired. The results suggest that the IMHV is critical for storing information having a direct influence on filial preferences.
