Behavioral effects of neurotensin in the open field: structure-activity studies. 1986

P J Elliott, and J Chan, and Y M Parker, and C B Nemeroff

The behavioral effects of intracerebroventricularly administered neurotensin (NT), some NT fragments and two synthetic NT analogs were investigated in the open field. Each peptide was studied in both a 'novel' (no pre-exposure) and a 'familiar' (with pre-exposure) environmental situation. Neurotensin decreases locomotor activity in the periphery but increases the time spent in the central area of the apparatus. Of the congeners tested, D-Phe11-NT has similar effects to NT whereas the NT fragments were generally inactive. These findings indicate that the intact peptide or stable substituted NT analogs, but not small C- and N-terminal fragments of NT, are behaviorally active after intraventricular administration.

D009043 Motor Activity Body movements of a human or an animal as a behavioral phenomenon. Activities, Motor,Activity, Motor,Motor Activities
D009496 Neurotensin A biologically active tridecapeptide isolated from the hypothalamus. It has been shown to induce hypotension in the rat, to stimulate contraction of guinea pig ileum and rat uterus, and to cause relaxation of rat duodenum. There is also evidence that it acts as both a peripheral and a central nervous system neurotransmitter.
