Consummatory behavior

Mood and hedonic value associated with feeding, food intake, foraging, consummatory behaviors, and craving in addiction complex regulation by food entrainable oscillators in the brain and periphery, neuropeptides (including orexins) and biogenic amines.

Consummatory Behavior - Rats treated with moderate doses of PCPA consume laboratory food and water normally,10b,19c,22 ut appear to be more finicky or responsive than controls in their consumption of solutions of alcohol, 22, 23 saccharin,23c dextroselOh or quinine,18 suggesting that gustatory or olfactory thresholds may be lowered by PCPA. 

The Lorenz-Craig model Appetitive behavior - releasing stimulus situation - consummatory act was later modified by N. Tinbergens hierarchy model of appetite behaviors (for details see I. Eibl-Eibesfeldt 1975, 1987). 

We have argued that psychostimulants, by releasing DA in the NAc, eventually mimic the appetitive/incentive component rather than the consummatory component of natural reward and the behavioral impact of conditioned stimuli rather than of unconditioned ones (Di Chiara, 1998). Consistent with this hypothesis is the circumstance that food reward induces hedonia independently from DA, in contrast with psychostimulant reward, which is mediated by the activation of DA transmission in the NAc shell. A problem with this hypothesis however derives from the observation that the ability to release DA in the... 

THE CRAIG-LORENZ-TINBERGEN CONCEPTUALIZATION OF CONSUMMATORY AND APPETITIVE BEHAVIORS... 

Contrary to the consummatory action, appetitive behavior is not characterized by a stereotyped motor pattern, but rather by (1) its variability and plasticity and (2) its purposiveness.. . ... 

The consummatory act is relatively simple, at its most complex, it is a chain of reactions, each of which may be a simultaneous combination of a taxis and a fixed pattern. But appetitive behavior is a true purposive activity, offering all the problems of plasticity, adaptiveness, and of complex integration that baffle the scientist in his study of behavior as a whole. Appetitive behavior is a conglomerate of many elements of very different order, of reflexes, of simple patterns like locomotion, of conditioned reactions, of insight behavior, and so on. (Tinbergen, 1951, pp. 105-106)... 

Lorenz (1981) recognized that some appetitive behaviors are FAPs, endogenously released and terminated upon detection of the key stimulus for the consummatory act that is the objective of the search. But, he did not develop the theoretical implications of this idea. Instead we must turn to the Russian physiologists who have spent 50 years studying orienting reflexes (Sokolov, 1963 Voronin et al., 1965, see also Berlyne, 1960). 

Rice and Church (106) presented evidence that black-tailed deer prefer distilled water treated with low concentrations of water or ethanol extracts from foods normally accepted by deer (bitter brush, Douglas-fir, and hemlock). In response to certain organic acids commonly found In plants browsed by ungulates, there were pronounced sex differences. Bucks strongly preferred the intermediate concentrations of malic acid but showed weaker preference for succinic and citric acids. Does, on the other hand, showed weak to strong rejection of these same acid concentrations. This report indicated that extracted flavor compounds found In natural food sources of black-tailed deer can greatly affect their consummatory drinking behavior.
