"Learned safety" as a mechanism in long-delay taste-aversion learning in rats.
Rats learn taste aversions with unusually long CS-US delays. This has previously been explained as slow decay of a CS trace or as relative lack of interference. We propose, however, that the CS-US delay gradient is a learning curve: During the delay, a rat gradually learns that a taste is "safe." A solution which a rat drinks only once becomes safe and resistant to learned aversions for at leas...
متن کاملHippocampus, Ageing, and Taste Memories TatianaManrique, IgnacioMorón,M Angeles Ballesteros, RosaMGuerrero
Previous studies have shown that ageing may induce deficits in hippocampal-dependent learning and memory tasks, the spatial task being most extensively applied in rats. It is proposed that taste learning and memory tasks may assist in understanding the ageing of memory systems, giving access to a more complete picture. Taste learning tasks allow us to explore a variety of learning phenomena in ...
متن کاملNeuronal representation of conditioned taste in the basolateral amygdala of rats.
Animals develop robust learning and long lasting taste aversion memory once they experience a new taste that is followed by visceral discomfort. A large body of literature has supported the hypothesis that basolateral amygdala (BLA) plays a critical role in the acquisition and extinction of such conditioned taste aversions (CTA). Despite the evidence that BLA is crucially engaged during CTA tra...
متن کاملTaste aversion learning and schedule-induced polydipsia in rats
Experiment 1 sought to determine whether schedule-induced drinking could be abolished by means of a taste aversion. Polydipsic rats were given access to a .4% saccharin solution while they were exposed to an intermittent food schedule. Immediately after the session, they received an intraperitoneal injection of either lithium chloride or sodium chloride. Following a recovery day with water in t...
متن کاملParabrachial unit activities after the acquisition of conditioned taste aversion to a non-preferred HCl solution in rats.
Abstract In a behavioral experiment, rats reliably acquired a taste aversion to non-preferred 0.01 M HCl that had been previously paired with intraperitoneal injection of 0.15 M LiCl. These rats showed aversions to other acidic solutions such as malic acid and tartaric acid. In a neurophysiological experiment, the neuronal activities of the parabrachial nucleus (PBN) were recorded after the acq...
