TRANSCRIPT
Motor Function German physicians Gustav Fritsch and Eduard Hitzig discovered they could make different body parts move by mild electrical Stimulation. The arch shaped region that controls movement is the motor cortex
Mapping the Motor Cortex
Otfrid Foerster and wilder Penfield mapped
the motor cortex by stimulating different
cortical areas according to parts they controlled.
It was discovered that one side of the brain
controlled the other (left side of brain controls
right side of body)
Neural ProstheticsBrown University conducted a study to monitor when monkeys would move or think to move the monitor and later predict brain signals using recording electrons
With the findings researchers programmed a cursor to move to the monkeys thinking
In 2004 a trial for neural prosthetics on paralyzed humans allowed a tester to control a t.v. draw shapes on a computer and play video games.
Sensory Function The sensory cortex (discovered by Penfield) is a cortical area that specializes in getting information from the skin senses and from movement of the body.The more sensitive a body region the larger the sensory cortexScientist have identified other areas where the cortex receives input other than touch
Such as; optical lobes which receives visual information
Association Areas
They association various sensory inputs with stored memories- a very important
part of thinking.
