Studies of connections between locus coeruleus and cerebral cortex.


Small tracking electrodes were inserted into the cat locus coeruleus (LC), and the effects of LC stimulation were determined on the transcallosal potential (TCP) evoked in cerebral cortex on the same side. LC stimulation at 8 volts inhibited TCP amplitude an average of 11%. Rostral LC placements appeared most effective. LC stimulation, without drugs, did… (More)
