Eyeblink conditioning is associated with motor learning, which requires the cerebellum and the brainstem. This article provides behavioral data on whether JNJ16259685, a selective metabotropic glutamate receptor type 1 (mGluR1) antagonist, affects eyeblink conditioning in wild-type mice (C57BL/6 J strain). The dataset contains four types of behavioral outputs pertinent to eyeblink conditioning. We used a -test and an analysis of variance (ANOVA) to analyze the percentage of conditioned responses (CR%), peak CR latencies, onset CR latencies, and electromyography (EMG) amplitudes. The information obtained in this dataset adds to our knowledge of the molecular mechanisms underlying eyeblink conditioning and can prove beneficial for investigators studying the pharmacological effects of mGluR1 on motor learning. Future research might use this dataset as a basis for conducting experiments with different JNJ16259685 doses, administration methods, and durations than the ones used in the described procedures.

Eyeblink conditioning is mediated by similar cerebellar pathways in humans and animals and is typically investigated using delay or trace protocols. These studies show that humans can easily acquire eyeblink conditioning within a single day of training whereas animals usually require around 3-10 days of acquisition training before they consistently exhibit conditioned responses. We aimed to study how a multiple-day acquisition training, across 3 non-consecutive days of a month, with 100 trials per day affected learning in young human adults.

Objectives: The differential diagnosis of functional and other etiologies of dystonia can be difficult. We performed a clinical neurophysiological study in a female patient with cranial-cervical dystonia, providing strong evidence for the diagnosis of functional dystonia.
Methods: The patient had torticollis and intermittent facial pulling with downward deviation of the left angle of the mouth.

Cerebellum (CB) interactions with forebrain systems contribute to learning cognitive and motor tasks, but the nature of these interactions is unknown. Trace eyeblink conditioning (EBC) is an excellent associative learning paradigm for examining interactions between forebrain systems and CB. The anterior cingulate cortex (ACC), central amygdala (AM), and CB are essential for trace EBC, and we previously recorded changes in neuronal activity in these areas during learning with paired presentations of the conditional stimulus (CS) and unconditional stimulus (US).

Mossy fiber inputs are transformed into cerebellar Purkinje cell (PC) outputs by granule cell (GC)-dependent processing. Cerebellar dysfunction leads to motor, learning, emotional, and social deficits that are usually attributed to altered PC firing arising from impaired processing of mossy fiber inputs, even though PCs also fire independently of GCs. To isolate their contributions to cerebellum-dependent behaviors, we either disrupt GC signaling while leaving PC firing intact, or disrupt PC signaling to eliminate the influence of PCs.

Nitric oxide (NO) is a versatile signaling molecule with significant roles in various physiological processes, including synaptic plasticity and memory formation. In the cerebellum, NO is produced by neural NO synthase and diffuses to influence synaptic changes, particularly at parallel fiber-Purkinje cell synapses. This study aims to investigate NO's role in cerebellar learning mechanisms using a biologically realistic simulation-based approach.
