IS IT IMPORTANT THAT THE MIND IS IN A BODY - INHIBITION AND THE HEART

The hypothesis is advanced that certain inhibitory processes necessarily involve autonomic adjustments. Such adjustments would represent a constraint on information processing imposed by the location Of the mind in a body. Evidence is reviewed showing that motoric inhibition is related to a transient delay in heartbeat generation. The delay is shown to further depend upon when inhibition occurs in the cardiac cycle. it is argued that this form of interaction between central and autonomic nervous system Processing may be common. Central nervous system processes that may control inhibition and integrate information processing with motoric and autonomic processes are discussed.
