Abstract

Bilateral ablation of the telencephalon on the 1st posthatch day prevented learning from imprinting to colored stimuli in Japanese quail chicks C. coturnix japonica, but it spared their artificially selected approach preferences for particular colors and patterns. Postimprinting decerebration on the 3rd posthatch day erased the imprinted memory, but did not revert the chicks' approach choices to the colors of their genetically distinct initial preferences. The genetically determined and the acquired preferences were both lost in the latter birds, regardless whether they were imprinted to the initially preferred or the initially nonpreferred stimuli before decerebration. Discussion focuses on implications of the data for modeling specific interactions between and the interrelated neural representation of genetic and environmental influences in early behavioral development.
