The effects of concurrent timed-interval finger tapping on trace eyeblink conditioning in college students
… the involvement of cerebellar cortex in trace eyeblink conditioning by utilizing the traditional dual-task design. Timed-interval finger tapping, a motor function mediated by the cerebellar cortex, and several different cognitive tasks representing dissociable distributed brain memory systems …

An investigation of the integrity of two components of the cerebellar neurocircuitry involved in classical eyeblink conditioning in children prenatally exposed to alcohol: a magnetic resonance spectroscopy and functional magnetic resonance imaging study
Impairment in classical eyeblink conditioning (EBC) has previously been reported in children with fetal alcohol spectrum disorders (FASD) (Jacobson et al., 2008). The deep cerebellar nuclei and cerebellar cortex are critical elements of the cerebellar-brainstem circuitry that mediates EBC (Green et …

Comparison of the Effects of Introversion, Extraversion and Anxiety on Conditioning.
… varied independently in a 2 x 2 x 2 study of eyeblink conditioning and extinction. The Eysenck Personality Inventory and the Taylor Manifest Anxiety Scale were given to 167 college students of both sexes to measure individual differences in extraversion and anxiety, respectively. Students who …

Examination of neocortical plasticity during forebrain-dependent trace-associative learning tasks
… different time points of learning is trace-eyeblink conditioning. During eyeblink conditioning, subjects are presented with a neutral, conditioned stimulus (CS) (i.e., tone or whisker deflection) paired with a salient, unconditioned stimulus (US) (i.e., mild periorbital eyeshock) to elicit …

An Associative Memory Trace in the Cerebellar Cortex
Classical conditioning of motor responses, e.g., the eyeblink response, depends on the cerebellum. In the theoretical works of David Marr (1969) and James Albus (1971), it was proposed that Purkinje cells in the cerebellar cortex learn to associate the neutral conditioned stimulus with the …

Neuroimaging study of prenatal alcohol exposure effects on structural and functional connectivity in children
… PFAS (FAS/PFAS). Mediation of effects of PAE on eyeblink conditioning (EBC) provided statistical evidence that poorer microstructural integrity in these regions may play an important role in the EBC deficit observed in children with FASD. The FAS/PFAS children also revealed lower FA and/or higher …

A Purkinje cell Timing Mechanism. On the Physical Basis of a Temporal Duration Memory.
… Timing-dependent learning can be studied in eyeblink conditioning. If a neutral conditional stimulus is paired with an unconditional blink-eliciting stimulus, at an ISI of fixed duration, it acquires the ability to elicit a blink that peaks near the end of the ISI. Cerebellar Purkinje cells …

Higher Order Conditioning of the Eyeblink Reflex
Classical conditioning of the eyeblink response is a well-established model of cerebellar-dependent associative motor learning. In this paradigm an initially neutral conditioned stimulus (CS - e.g. an auditory tone or light) that elicits no response is paired with an aversive unconditioned stimulus …

Eyelid conditioning in mice reveals an interaction between stress and familial Alzheimer's disease
… An associative learning model called eyelid conditioning is often used to study mechanisms and modulatory processes governing cerebellar motor learning. Here, I implemented this task in head-fixed mice, then probed learning in two mouse models of Alzheimer Disease. Triple-transgenic (3xTg) …

Feedback control of cerebellar learning
… approached from within the paradigm of classical conditioning, in which a subject, through repeated presentations of a conditional stimulus, followed by an unconditional stimulus, acquires a conditioned response. Importantly, the conditioned response is timed so that it anticipates the …
