Ontogeny of delay versus trace eyeblink conditioning in the rat.
The ontogeny of delay versus trace eyeblink conditioning was examined in 19-, 23-, and 30-day-old rat pups. Pairings of a tone conditioned stimulus (CS) and periocular shock unconditioned stimulus (US; 100-ms) were presented in one of three conditioning paradigms: standard delay [380-ms CS, 280-ms interstimulus interval (ISI)], trace (380-ms CS, 500-ms trace interval), or long-delay (980-ms CS,...
متن کاملOntogeny of eyeblink conditioning using a visual conditional stimulus.
The developmental emergence of associative learning in rodents is determined by interactions among sensory, motor, and associative systems that are engaged in a particular experimental preparation (Carter & Stanton, 1996; Hunt & Campbell, 1997; Rudy, 1992). In fear conditioning, chemosensory, auditory, and visual cues emerge successively as effective conditional stimuli (CS) during postnatal on...
متن کاملDisruption of cerebellar maturation by an antimitotic agent impairs the ontogeny of eyeblink conditioning in rats.
This study represents an attempt to establish a relationship between maturation of the cerebellum and the ontogeny of eyeblink conditioning in the rat. Experiments 1 and 2 examined the effects of disrupting cerebellar maturation by neonatal exposure to the antimitotic agent methylazoxymethanol (MAM) on the ontogeny of eyeblink conditioning in infant rats. Experiment 1 demonstrated that neonatal...
متن کاملthe impact of morphological awareness on the vocabulary development of the iranian efl students
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
15 صفحه اولCerebellar secretin modulates eyeblink classical conditioning.
We have previously shown that intracerebellar infusion of the neuropeptide secretin enhances the acquisition phase of eyeblink conditioning (EBC). Here, we sought to test whether endogenous secretin also regulates EBC and to test whether the effect of exogenous and endogenous secretin is specific to acquisition. In Experiment 1, rats received intracerebellar infusions of the secretin receptor a...
