Findings to date are as follows a Most cells recorded in the mMGN show modulated activity during both the acoustic conditioned stimulus CS and the trace interval between the CS and the unconditioned stimulus US. b Modulation of activity is more likely on CS trials than CS- trials and on trials with conditioned responses than on trials without conditioned responses. c Differences in modulation of activity is primarily expressed as phasic bursts of firing. These observations are basically consistent with related work in other laboratories that have employed other forms of conditioned behavior and in species besides rabbits. The new information this study Provides is that learning related activity occupies that trace interval.
