Extinction, reacquisition, and rapid forgetting of eyeblink conditioning in developing rats.
Eyeblink conditioning is a well-established model for studying the developmental neurobiology of associative learning and memory. However, age differences in extinction and subsequent reacquisition have yet to be studied using this model. The present study examined extinction and reacquisition of eyeblink conditioning in developing rats. In Experiment 1, post-natal day (P) 17 and 24 rats were t...
متن کاملContextual specificity of extinction of delay but not trace eyeblink conditioning in humans.
Renewal of an extinguished conditioned response has been demonstrated in humans and in animals using various types of procedures, except renewal of motor learning such as eyeblink conditioning. We tested renewal of delay and trace eyeblink conditioning in a virtual environment in an ABA design. Following acquisition in one context (A, e.g., an airport) and extinction in a different context (B, ...
متن کاملHippocampal ripple-contingent training accelerates trace eyeblink conditioning and retards extinction in rabbits.
There are at least two distinct oscillatory states of the hippocampus that are related to distinct behavioral patterns. Theta (4-12 Hz) oscillation has been suggested to indicate selective attention during which the animal concentrates on some features of the environment while suppressing reactivity to others. In contrast, sharp-wave ripples ( approximately 200 Hz) can be seen in a state in whi...
متن کاملTrace Eyeblink Conditioning and Extinction Contingent to Hippocampal Ripples in Rabbits
Two distinct hippocampal oscillatory states have been associated to functions in learning and memory. Theta oscillations (3 – 12 Hz) occurring during attentive exploratory behaviors are suggested to reflect the formation of new memory traces to the hippocampus. In a complementary function, sharp-wave ripples (~200 Hz) occurring during slow wave sleep and quiet restfulness, are essential for mem...
متن کاملRetention and extinction of delay eyeblink conditioning are modulated by central cannabinoids.
Rats administered the cannabinoid agonist WIN55,212-2 or the antagonist SR141716A exhibit marked deficits during acquisition of delay eyeblink conditioning, as noted by Steinmetz and Freeman in an earlier study. However, the effects of these drugs on retention and extinction of eyeblink conditioning have not been assessed. The present study examined the effects of WIN55,212-2 and SR141716A on r...
