Abstract

Hypnogenic (HS) or arousing (AS) stimulations of the small intestine (INT), splanchnic (SPL), and vagal (VAG) nerves were used to modify the predatory behavior (PB) elicited by stimulating the lateral hypothalamus (LHS). HS induced EEG synchronization and sleep. AS aroused the cat from slow-wave sleep. LHS induced the cat to attack an anesthetized rat and bite its neck after an exploratory activity. The following parameters of PB were determined: biting latency (BL), the interval between the beginning of LHS and the touching the rat by the cat's muzzle; exploratory time (ET), which begins with an environmental search and culminates in orienting toward the rat; attack time (AT), in which the cat stalks and bites the rat. HS, delivered for 5, 10, 15 min to INT, SPL, and VAG prior to LHS, increased BL and ET and did not affect AT. AS, delivered for 10 s to INT or VAG prior to LHS, decreased BL by reducing ET. SPL AS shortened BL by decreasing both ET and AT. The viscerosensory effects on PB were decreased by increasing the intensity of LHS; a ferocious attack with BL less than 10 s was not influenced by either HS or AS. These results indicate that the viscerosensory influence can modify PB by inhibiting or facilitating the priming events of the attack.
