Sixteen male Long-Evans rats were tested on a modified version of Flaherty et al.'s [Flaherty, C. F., Turovsky, J., & Krauss, K. L. (1994). Relative hedonic value modulates anticipatory contrast. Physiology and Behavior, 55, 1047-1054.] anticipatory contrast paradigm to assess memory for the anticipation of reward. Prior to testing each rat received either a control or quinolinic acid induced lesion of the agranular insular cortex. In the home cage, each rat was allowed to drink a water solution containing 2% sucrose for 3 min followed by a water solution containing 32% sucrose for 3 min. Across 10 days of testing, the control rats showed significantly increased anticipatory discriminability as a function of days. In contrast, rats with agranular insular cortex lesions failed to show anticipatory discriminability. The results of a preference task revealed that both groups could perceptually discriminate between a 2% and a 32% sucrose solution. The data suggest that the agranular insular cortex may be involved in the anticipation of reward. 相似文献

Probabilistic epigenesis 总被引:1,自引:0,他引:1
Gottlieb G 《Developmental science》2007,10(1):1-11
The notion that phenotypic traits, including behavior, can be predetermined has slowly given way in biology and psychology over the last two decades. This shift in thinking is due in large part to the growing evidence for the fundamental role of developmental processes in the generation of the stability and variations in phenotype that researchers in developmental and evolutionary sciences seek to understand. Here I review the tenets of a metatheoretical model of development called probabilistic epigenesis (PE) and explore its implications for furthering our understanding of developmental and evolutionary processes. The PE framework emphasizes the reciprocity of influences within and between levels of an organism's developmental manifold (genetic activity, neural activity, behavior, and the physical, social, and cultural influences of the external environment) and the ubiquity of gene-environment interaction in the realization of all phenotypes. 相似文献
