Spontaneous recovery of consummatory behavior, but not of consummatory successive negative contrast
Five experiments were designed to study spontaneous recovery (SR) in two situations involving consummatory behavior: consummatory successive negative contrast (cSNC) and consummatory extinction (cE). SR of consummatory suppression should occur if incentive downshift induces an egocentric memory encoding information about the emotional reaction to the downshift that is counterconditioned or exti...
متن کاملConsummatory Successive Negative Contrast Induces Hypoalgesia
Aires, Ciencia y Tecnología, and by Grant 02782 from Consejo Nacional de Investigaciones Científicas y Técnicas, Argentina, to A.E.M. The authors wish to express their thanks to Carlos Baratti and Cristina Acevedo for facilitating the use of the hot plate. María de los Angeles D ́Ambros and Pablo Gomez contributed to the training of rats for this experiment. Correspondence concerning this articl...
متن کاملInsular cortex and consummatory successive negative contrast in the rat.
Rats that are expecting a high value reward (e.g., 1.0 M sucrose) show an exaggerated underresponding when they are instead given a low value reward (e.g., 0.15% saccharin), an effect termed successive negative contrast (SNC). In the present experiment, insular cortex-lesioned (ICX) rats showed normal responsivity to sucrose and saccharin prior to the reward downshift. However, when switched fr...
متن کاملOpioid receptors modulate recovery from consummatory successive negative contrast.
Three experiments explored the role of the opioid system in consummatory successive negative contrast. In Experiment 1, rats treated with the nonspecific opioid-receptor antagonist naloxone (2mg/kg) exhibited increased suppression after a shift from 32% to 6% sucrose solution (32-->6), relative to 6-->6 unshifted controls. A similar but shorter effect was observed with the delta-opioid receptor...
متن کاملEffect of Neonatal Clomipramine Treatment on consummatory Successive Negative Contrast
Neonatal administration of clomipramine (CLI) produces physiological, neuroendocrinal and behavioral abnormalities in rats when they reach adulthood, which are similar to those observed in animal models of depression. In consummatory successive negative contrast (cSNC), rats that have had experience drinking 32% sucrose solution drink significantly less 4% sucrose solution than rats that have d...
