    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cerebellum; Purkinje cell; Timing; Temporal; Memory; Eyeblink conditioning; mGluR7; Kir3; GIRK;

    Abstract : The standard view of neural signaling is that a neuron can influence its target cell by exciting or inhibiting it. Learning is thought to involve strengthening or weakening synaptic connections. For most behaviors, the brain must learn to produce precisely timed activity patterns. READ MORE
