Document Summary
Regulates glands and muscles of internal organs. Controls heartbeat, respiration, digestion, and dilation of pupils. Active during processes that restore the body"s reserve of energy. Transmits messages from sensory receptors to the brain and from the brain to. Interneurons transmit neural impulse from sensory neuron communication with motor neurons in some reflexes. Touch hot stove stimulates sensory receptors sensory neurons send signal to spinal cord interneurons excite motor neurons motor neurons leave spinal cord & excites muscles to pull away. Goal is to trace the connections to and from a given neuron/region of brain. Example: diffusion tensor imaging (dti) allows us to map out connection pathways in. Examining brain activity while an individual performs some type of behavior. Generates maps of blood flow and oxygenation within the brain. Records electrical signals on surface of scalp that are generated by electrical activity in nearby brain regions. Used to record magnetic fields that company electrical activity in the brain.
