Document Summary
Neurons are active when someone performs a movement and when we perform a movement. Same neurons control action observation and movement production. Shows mirror neurons selectively active when observing and performing. One of the most critical findings in science in 40 years why we can develop sophisticated manual skills and language with mirror neurons, freeing more brain area to develop language. Also said that this action observation system keeps us at the top of the food chain. Output to spine is less than primary motor cortex (much less output than m1) Connections terminate on alpha motor neurons that innervate hand and finger musculature. Selectively active for internally generated movement: sma neurons make up commands allowing us to move when we want. Sequence specificity: increasing the complexity of the movement will significantly involve sma. Motor-imagery task: sma is active and facilitates sport performance/rehab plasticity in sma. Supplementary motor area (sma): unilateral lesion (sma lesion)
