Appetitive and aversive outcome associations modulate exogenous cueing
In two experiments, we utilized an exogenous cueing task in which different-colored abrupt-onset cues were associated with an appetitive (gain of 10 cents), aversive (loss of 5 cents), or neutral (no gain or loss) outcome. Reward delivery did not depend on performance, but instead the specific exogenous cues were always followed by their corresponding outcome in a classical-conditioning-like ma...
متن کاملBDNF deletion or TrkB impairment in amygdala inhibits both appetitive and aversive learning.
Brain-derived neurotrophic factor (BDNF) is known to have an integral role in establishing stable memories after learning events. The neuroplasticity induced by Pavlovian fear conditioning has likewise been shown to rely on interactions between BDNF and its principal receptor, tyrosine kinase receptor B (TrkB), in the amygdala after training. Although the necessity of amygdala bdnf expression a...
متن کاملDifferential involvement of the central amygdala in appetitive versus aversive learning.
Understanding the function of the distinct amygdaloid nuclei in learning comprises a major challenge. In the two studies described herein, we used c-Fos immunolabeling to compare the engagement of various nuclei of the amygdala in appetitive and aversive instrumental training procedures. In the first experiment, rats that had already acquired a bar-pressing response to a partial food reinforcem...
متن کاملAppetitive and Aversive Learning in Spodoptera littoralis Larvae
Page 725 Adult butterflies are capable of associative learning that serves foraging flowers or finding oviposition sites. In experimental paradigms, they learn to extend their proboscis in response to floral orders associated with a sugar reward or to avoid them if paired with bitter substances. Such settings have been used to elucidate the neuronal circuitry and mechanisms underlying the afore...
متن کاملAppetitive and Aversive Visual Learning in Freely Moving Drosophila
To compare appetitive and aversive visual memories of the fruit fly Drosophila melanogaster, we developed a new paradigm for classical conditioning. Adult flies are trained en masse to differentially associate one of two visual conditioned stimuli (CS) (blue and green light as CS) with an appetitive or aversive chemical substance (unconditioned stimulus or US). In a test phase, flies are given ...
