Abstract

Paired electrical stimulation of 1 lateral geniculate nucleus (LGN) in 14 rabbits with septal (N = 6) or hypothalamic (N = 8) stimulation as the UCS, whereas stimulation of the contralateral LGN was presented unpaired with the UCS. Heart rate (HR) but not blood pressure (BP) discriminations were formed between geniculates. UCR and CR HRs were decreases in normal rate. Latency of the BP UCR consisting of an elevation of mean pressure was shorter than that of the HR UCR. The HR CRs occurred in the absence of BP CRs. Results agree with previous rabbit conditioning studies which used peripheral shock as the UCS and found that development, but not elaboration of the HR CR, is influenced by unconditioned increases in BP.
