Studying the Brain and how it works

Studying the Brain Electroencephalogram: EEG; amplified recording of brain wave activity over the surface of the brain. CT Scan (CAT Scan): a series of X-Rays photos taken from different angles to detect abnormalities. PET Scan: visual display of brain activity that detects a radioactive form of glucose when brain is active. MRI: uses magnetic fields to produce computer images of soft tissue. fMRI: reveals blood flow and brain activity by comparing successive MRIs

Brainstem Central core of the brain; controls automatic survival functions. Medulla: base of brain stem; controls heartbeat and breathing. Pons: above medulla; help coordinate movement. Reticular Formation: Nerve network that travels through brainstem and thalamus; controls arousal. Thalamus: top of brainstem; brain’s sensory control center; directs sensory messages to parts of the brain.

Cerebellum Little Brain Rear of brainstem Processes sensory input, coordinates movement output and balance, and enables nonverbal learning and memory.

Limbic System Neural system that controls emotion and motivation. Hippocampus: processes conscious memories. Amygdala: controls aggression and fear. Hypothalamus: controls eating, drinking, and body temperature.
