Brain StructuresA. BrainstemB. ThalamusC. CerebellumD. Limbic SystemCurrent LectureI. Neuroimaging TechniquesA. CT Scani. Shows the structure, not the activity.B. PET Scan (Position Emission Tomography)ii. Shows the activity of the brain.C. MRI (Magnetic Resonance Imaging)iii. Shows the structure, not the activity.D. FMRI (Functional MRI)iv. So, gives a picture of activity in the brain.II Brain StructuresA. Brainstormi. Medulla1) Controls the heartbeat and breathing.a) If there’s any damage to this you’ll either be on life support or you’ll die.These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.ii. Reticular Formation1) Relays the information to the upper part of the brain.2) Involved in controlling breathing, heartbeat, blood pressure, swallowing, urination and movements of the face and the tongue.3) Sleep, wakefulness and arousal are also involved with reticular formation.B. Thalamusi. Sends sensory information to the higher levels of the brain for processing.ii. Acts as a relay station to the upper brain.1) Except for the sense of smell.C. Cerebellumi. Coordinates voluntary movement.ii. If damaged it ruins your coordination.1) Affected when drinking, inhibits that coordination.D. Limbic Systemi. Involved in emotion, memory and motivation.ii. Amygdala1) Linked to emotion.a) Especially rage and fear.a. Expressing it and recognizing
