# ORIGINS AND DEVELOPMENT OF INGESTIVE BEHAVIOR

> **NIH NIH R01** · DUKE UNIVERSITY · 1994 · $122,235

## Abstract

A developmental analysis of ingestive behavior is proposed.  The expression
and control of individual components in the ingestive sequence will be
studied in young rats.  Particular emphasis will be placed on the
investigation of the decrementing property of the oral response component
which will be tested for its generality, duration, and potency.  This
intrinsic, habituation-like mechanism could be a principle integrator of
ingestion-related signals.  An integrative function for oral habituation
would be indicated by influences of physiological state and postingestive
signals on habituation parameters such as the initial level of
responsiveness, rate of decrement, or duration of decrement.  The relation
of the oral component to other earlier components in the sequence will be
assessed in experiments measuring olfactory orienting, and the potential
brainstem representation of the oral habituation process will be evaluated
in decerebrate pups.  The proposed experiments offer a unique conceptual
strategy and should provide instructive data on the neurobehavioral
organization of a most fundamental appetitive behavior.
