Document Summary
Watch hand motions and engage in hand motion: superior temporal sulcus-watches biological movement; only mirror-neurons, none of them engage in performing biological movement in the individual, human brain: sensory, associatory, engaging, human mirror-neuron system. Posterior sts, rostral ipc, prefrontal cortex, ventral pmc. Visual input & human mirror-neurons: mirror-neurons as foundation of human sociology, psychology, and understanding. This is because there are sensory receptors on the skin. Experiencing someone else"s touch in your mind-only difference is the skin between the people feeling similar things. Hand doing movement vs. tool putting food on the plate: no direct evidence of mirror neurons in humans, mu rhythm-suppressed when the brain is engaged in doing, seeing, or imaging action. Seems to correlate to mirror neuron activity. In most people, the mu wave is suppressed both in response to their own movement and to observing the movement of others. Excitatory & inhibitory neurons-located in motor cortex: fmri-shows regions activated when performing an action and.
