Motor Learning 1986 - present.

• Understanding task rules and strategies. Learning "what" to do often precedes learning "how" to do it. [selected references]
• Learning of movement strategies and tactics depends on limbic functions.

Motor control: neural circuits supporting movements made in task context 1969 - present

• Practiced simple movements can be identified by their velocity profile. [selected references]
• Long loops through primary motor cortex participate in intended force production.
  [selected references]
• The cerebellum advances time of pyramidal output for practiced movements.
  [selected references]
• The basal ganglia are needed for remembered task movements. [selected references]

Organization of primary motor cortex 1957 - 1969 [selected references]

• Sensory inputs to primary motor cortex are various and converge in radial cell columns.
• Role of the pyramidal system in motor control.

 Recurrent inhibition focuses motor output 1957 - 1969 [selected references]

• Spinal recurrent inhibition separates active motoneuron pools.
• Cerebral recurrent inhibition focuses pyramidal responses in motor cortex to peripheral input.
• Spinal and cerebral recurrent inhibitions are equally efficient.
• Rubral recurrent inhibition balances cerebral and cerebellar influences on the spinal cord.

Transmitter release and neurotoxins 1949 - 1965 [selected references]

• Botulinum toxin inactivates cholinergic junctions in muscle and spinal cord.
• Tetanus toxin inactivates inhibitory synapses in spinal cord and cerebral cortex.
