Abstract

Neurotensin and bombesin have been tested for their effects on body temperature and locomotor activity in an open field. Both peptides induce hypothermia and suppress ambulation and rearing. The time curves of the hypothermic effects of both peptides appear to be rather similar, although bombesin is a more potent hypothermic agent than neurotensin. The time curves of the effects on locomotor activity appear to be quite different. The suppressive effect of neurotensin on locomotor activity is relatively short lasting and reaches its maximum at approximately 32 minutes. The effect of bombesin follows a different time curve and shows two peaks, suggesting that two different mechanisms are involved in the suppressive action of bombesin on locomotor activity. Calculation of the correlation coefficients between the effects of neurotensin and of bombesin on body temperature and on locomotor activity (ambulation) suggest that a causal relationship between these two effects is not likely, in particular for neurotensin
