Document Summary
Mirror neurons: found in the frontal lobe (near the motor cortex) and in the parietal lobe. Found in birds, monkeys, humans: active when an animal performs a behavior, such as reaching for or manipulating an object, activated when another animal observes that animal performing the same behavior. London cabbies have differences in spatial memory (mapping the city): phantom limb: stimulating the face or arm produced phantom limb sensations in the amputees; they reported feeling a sensation in their missing limbs. Beginning at birth, the connections among neurons proliferate. As infants learn, they form more branches and more neural networks. In the womb, the number of neurons grows by about 750,000 new cells per minute in the middle trimester of pregnancy. In infancy, the growth in neural connections takes place initially in the less complex parts of the brain (the brainstem and limbic system), as well as the motor and sensory strips. This enables body functions and basic survival skills.
