Project description:This SuperSeries comprises the following subset Series:; GSE3651: The AIN-centered DCN of delayed-type eyeblink conditioned mice: 3-d paired training and sham negative control groups; GSE3652: The AIN-centered DCN of delayed-type eyeblink conditioned mice: 7-d paired and 7-d unpaired training groups; Anterior interpositus nucleus (AIN) is a proposed site of memory formation of eyeblink conditioning. A large part of the underlying molecular events, however, remains unknown. To elucidate molecular mechanisms, we examined transcriptional changes in the AIN of mice trained with delayed-type eyeblink conditioning; The data are not directly comparable between GSE3651 and GSE3652, given the different experimental time periods and amounts of cRNA used for hybridizations. Experiment Overall Design: Refer to individual Series

Project description:Anterior interpositus nucleus (AIN) is a proposed site of memory formation of eyeblink conditioning. A large part of the underlying molecular events, however, remains unknown. To elucidate molecular mechanisms, we examined transcriptional changes in the AIN of mice trained with delayed-type eyeblink conditioning Experiment Overall Design: 7-d paired training group: Mice received a surgery for implanting four Teflon-coated stainless-steel wires in their left eyelid and a headstage on their head. After 3daysâ?? recovery, they were trained with paired paradigm of conditioned stimulus (CS) and unconditioned stimulus (US) for 7 days: A 352-ms tone CS (1kHz, 83~85dB) was delivered first and a 100ms periorbital shock US (100kHz square pluses) were delivered with 252ms after the onset of CS, and they co-terminated. In case of 7-d unpaired training group, A CS and a US were delivered in an explicitly unpaired, pseudorandomized manner for 7 days. After the last trial was given, anterior interpositus was immediately sampled in 10 to 30 min from the sacrifice.

Experiment Overall Design: Sham negative control group: Mice received a surgery for implanting four Teflon-coated stainless-steel wires in their left eyelid and a headstage on their head. After recovery, anterior interpositus nucleus-centered deep cerebellar nuclei were immediately sampled in 10 to 30 min from the sacrifice. Experiment Overall Design: ~10-15 anterior interpositus-centered deep cerebellar nuclei ipsilateral to the eye implanted with four wires were pooled into the same sham control or training group and subjected to microarray analysis.
Project description:Behavioral transitions Young infant rats paradoxically prefer odors paired with shock but older pups learn aversions. This transition is amygdala- and corticosterone-dependent. Microarray results showed downregulated dopaminergic presynaptic function in the amygdala with preference learning. Corticosterone injected 8-day-old pups and untreated 12-day-old pups learn aversions and had dopaminergic upregulation in the amygdala. 8 day saline or corticosterone treated- or 12 day old untreated rat pups were trained with odor-shock pairings. Immediately after training pups were sacrificed and the amygdala dissected out. Controls were unpaired shock-odor groups.Paired and unpaired groups were processed together for each experimental condition. Paired and unpaired data were compared by ranked products.
Project description:safety versus fear conditioning. Mice were trained with 4 unpaired (Safety) or paired (Fear) CS-US presentations over 3 days. Mice were killed by decapitation 4hrs after the last training session.
