Wells, Audrey M.; Lasseter, Heather C.; Xie, Xiaohu; Cowhey, Kate E.; Reittinger, Andrew M.; Fuchs, Rita A. – Learning & Memory, 2011
Contextual stimulus control over instrumental drug-seeking behavior relies on the reconsolidation of context-response-drug associative memories into long-term memory storage following retrieval-induced destabilization. According to previous studies, the basolateral amygdala (BLA) and dorsal hippocampus (DH) regulate cocaine-related memory…

Lozano, J. H.; Hernandez, J. M.; Rubio, V. J.; Santacreu, J. – Learning and Individual Differences, 2011
Although intelligence has traditionally been identified as "the ability to learn" (Peterson, 1925), this relationship has been questioned in simple operant learning tasks (Spielberger, 1962). Nevertheless, recent pieces of research have demonstrated a strong and significant correlation between associative learning measures and intelligence…

Sekiguchi, Tatsuhiko; Furudate, Hiroyuki; Kimura, Tetsuya – Learning & Memory, 2010
The terrestrial slug "Limax" exhibits a highly developed ability to learn odors with a small nervous system. When a fluorescent dye, Lucifer Yellow (LY), is injected into the slug's body cavity after odor-taste associative conditioning, a group of neurons in the procerebral (PC) lobe, an olfactory center of the slug, is labeled by LY. We examined…

Martel, Guillaume; Hevi, Charles; Friebely, Olivia; Baybutt, Trevor; Shumyatsky, Gleb P. – Learning & Memory, 2010
Synaptically released Zn[superscript 2+] is a potential modulator of neurotransmission and synaptic plasticity in fear-conditioning pathways. Zinc transporter 3 (ZnT3) knock-out (KO) mice are well suited to test the role of zinc in learned fear, because ZnT3 is colocalized with synaptic zinc, responsible for its transport to synaptic vesicles,…

Holland, Peter C. – Learning and Motivation, 2008
In experiments that measured food consumption, Holland (1981; "Learning and Motivation," 12, 1-18) found that food aversions were formed when an exteroceptive associate of food was paired with illness, but not when such an associate was paired with shock. By contrast, measuring the ability of food to reinforce instrumental responding,…

Ohno, Masuo; Tseng, Wilbur; Silva, Alcino J.; Disterhoft, John F. – Learning & Memory, 2005
Little is known about signaling mechanisms underlying temporal associative learning. Here, we show that mice with a targeted point mutation that prevents autophosphorylation of [alpha]CaMKII ([alpha]CaMKII[superscript T286A]) learn trace eyeblink conditioning normally. This forms a sharp contrast to the severely impaired spatial learning in the…
