The caudate nucleus and active avoidance

The caudate nucleus and avoidance learning: A reevaluation

“…It is suggested that an inappropriately place.d caudate lesion accounts for the failure to see deficits in Albert & Bignami's (1968) study and our study summarized here. Contrary to previous suggestion (Winocur & Mills, 1970), it is not a small anterior dorsal caudate lesion Bull. Psychon.…”

Effects of substantia nigra and caudate nucleus lesions on avoidance learning in rats.

“…The role of the caudate nucleus has been extensively investigated in avoidance learning situations. However, considerable apparent disagreement has occurred among the results of these studies (Kirkby, 1970;Winocur & Mills, 1970). There have been reports with both one-way and two-way avoidance training procedures where deficits were found while in others no deficits were seen.…”

“…There have been reports with both one-way and two-way avoidance training procedures where deficits were found while in others no deficits were seen. Winocur and Mills (1970) suggested that deficits are usually the finding with relatively large and more posterior caudate nucleus lesions, but deficits typically are not seen with smaller anterodorsal caudate nucleus lesions. This explanation is consistent with the literature on one-way avoidance learning, but it will not account for discrepancies in results seen with twoway avoidance training.…”
