Colon-Cesario, Wanda I.; Martinez-Montemayor, Michelle M.; Morales, Sohaira; Felix, Jahaira; Cruz, Juan; Adorno, Monique; Pereira, Lixmar; Colon, Nydia; Maldonado-Vlaar, Carmen S.; Pena de Ortiz, Sandra – Learning & Memory, 2006
Nurr1 expression is up-regulated in the brain following associative learning experiences, but its relevance to cognitive processes remains unclear. In these studies, rats initially received bilateral hippocampal infusions of control or antisense oligodeoxynucleotides (ODNs) 1 hour prior to training in a holeboard spatial discrimination task. Such…

Celerier, Aurelie; Pierard, Christophe; Rachbauer, Dagmar; Sarrieau, Alain; Beracochea, Daniel – Learning & Memory, 2004
The present study was aimed at simultaneously determining on the same subject, the effects of stress on retrieval of flexible (contextual or temporal) or stable (spatial) information. Three behavioral paradigms carried out in a four-hole board were designed as follows: (1) Simple Discrimination (SD), in which mice learned a single discrimination;…

Gottselig, Julie Marie; Brandeis, Daniel; Hofer-Tinguely, Gilberte; Borbely, Alexander A.; Achermann, Peter – Learning & Memory, 2004
We investigated learning-related changes in amplitude, scalp topography, and source localization of the mismatch negativity (MMN), a neurophysiological response correlated with auditory discrimination ability. Participants (n = 32) underwent two EEG recordings while they watched silent films and ignored auditory stimuli. Stimuli were a standard…
