Peculiar Modulation of Taste Aversion Learning by the Time of Day in Developing Rats Manrique, Tatiana Gámiz Ruiz, Fernando Morón Henche, Ignacio Ballesteros Duperon, María Ángeles Gallo Torre, Milagros Taste aversion Temporal context Adolescence Rats Latent inhibition Neophobia The ontogeny of the temporal context modulation of conditioned taste aversion was studied in male Wistar rats using a palatable 1% NaCl solution. A procedure that included two saline preexposures, a single pairing saline-lithium chloride (0.15 M; 1% b.w.) either at the same or a different time of day of preexposures and a one-bottle test at the same time than preexposure was applied. Four age groups (PN32, PN48, PN64, and PN100) covering the complete range from adolescence to the adult period were tested. The results showed no effect of a temporal context shift in PN32. A peculiar enhancement of temporal context specific saline aversions was exhibited by PN48 and PN64 rats, while the adult typical temporal context specificity of latent inhibition was only evident in PN100 rats. The results are discussed in terms of the peculiar brain functional organization during a protracted adolescence period. 2024-01-23T08:17:23Z 2024-01-23T08:17:23Z 2009-03-01 journal article https://hdl.handle.net/10481/87118 10.1002/dev.20354 eng http://creativecommons.org/licenses/by-nc-nd/4.0/ open access Attribution-NonCommercial-NoDerivatives 4.0 Internacional Wiley
