Marter, Kathrin; Grauel, M. Katharina; Lewa, Carmen; Morgenstern, Laura; Buckemüller, Christina; Heufelder, Karin; Ganz, Marion; Eisenhardt, Dorothea – Learning & Memory, 2014
This study examines the role of stimulus duration in learning and memory formation of honeybees ("Apis mellifera"). In classical appetitive conditioning honeybees learn the association between an initially neutral, conditioned stimulus (CS) and the occurrence of a meaningful stimulus, the unconditioned stimulus (US). Thereby the CS…

Associative Memory in Three Aplysiids: Correlation with Heterosynaptic Modulation
Peer reviewed Peer reviewed

Thompson, Laura; Wright, William G.; Hoover, Brian A.; Nguyen, Hoang – Learning & Memory, 2006
Much recent research on mechanisms of learning and memory focuses on the role of heterosynaptic neuromodulatory signaling. Such neuromodulation appears to stabilize Hebbian synaptic changes underlying associative learning, thereby extending memory. Previous comparisons of three related sea-hares (Mollusca, Opisthobranchia) uncovered interspecific…

Classical Conditioning of Eyelid and Mystacial Vibrissae Responses in Conscious Mice
Peer reviewed Peer reviewed

Delgado-Garcia, Jose Maria; Troncoso, Julieta; Munera, Alejandro – Learning & Memory, 2004
The murine vibrissae sensorimotor system has been scrutinized as a target of motor learning through trace classical conditioning. Conditioned eyelid responses were acquired by using weak electrical whisker-pad stimulation as conditioned stimulus (CS) and strong electrical periorbital stimulation as unconditioned stimulus (US). In addition,…

Contrasts in Infant Classical Eyeblink Conditioning as a Function of Premature Birth
Peer reviewed Peer reviewed
Direct linkDirect link
Herbert, Jane S.; Eckerman, Carol O.; Goldstein, Ricki F.; Stanton, Mark E. – Infancy, 2004
The impact of premature birth on associative learning was evaluated using simple delay eyeblink conditioning in which a tone conditional stimulus was paired with an air puff unconditional stimulus. Fourteen preterm (28-31 weeks gestation) and 11 full-term infants completed at least 3 conditioning sessions, 1 week apart, at 5 months of age…
