35. Mirror Neurons A. Activity in the neuron as the monkey observes another monkey make a precision group.B. Activity in the same neuron as the monkey observes the human experimenter make the precision grip.C. Activity in the same neuron as the monkey itself performs a precision grip. (From Rizzolottiet al 1996.)
36. Summary Primary Motor Cortex: Codes force and direction of movement Spinal motor neuron are directly under control for precise movement. Dorsal Premotor Cortex Movement related neuron encodes sensorimotor transformation for visual and sensory cue Fire before movement Ventral Premotor Cortex Encodes learned motor act fire before movement All cortical neurons are adaptable and plastic
43. Function of BG Voluntary movement Initiation of movement Control of ramp movement Change from one pattern to other Programming and correcting movement while in progress (thalamocortical circuts) Postural control Righting reflex Automatic associated movement (walking) Control of muscle tone Reticulospinal Vestibulospinal
54. Control of voluntary movement Execution Planning Basal Ganglia Association cortex Premotor + Motor cortex Movement Idea Lateral cerebellum Intermediate Cerebellum
