Electrical MicroStimulation of the Motor Cortex
A brief history and study of the motor cortex

These videos introduce the Motor Cortex in four section according to the major discoveries from the 18th, 19th, 20th ad 21st Centuries. Galvani, Volta, Fritsch, Hitzig, Ferrier, Penfield and Graziano all made significant contributions to the understanding of the motor cortex. Each of these pioneers applied some form of electrical stimulation to the motor cortex to reveal something of its function.

Electrical Microstimulation of the Motor Cortex remains the gold standard in determining its functioning. In other videos we will explore the theories for Motor Control which must include and define the findings of microstimulation of the motor cortex as well as the observed motor behavior and learning.

Muscles versus Movements: this has been a debate for 130 years since Hughlings Jackson proclaimed in 1889 that the motor cortex is concerned with movements not muscles. This video series follows a journey for this debate from the Frog to the Dog to the Monkey and on to the Human Motor Cortex.

Motor control is an important subject in Physical Therapy and the Feldenkrais Method, two methodologies that affect human functioning. Some background in how the brain works will allow for a better understanding of human functioning and how to affect it.

This a work in progress. In the future, more EPH, Optimal Motor Control Theory, Core Stabilization motor control theory, Active Inference and the Feldenkrais Method and motor control.
