PSYC 101 Lecture Notes - Lecture 5: Limbic System, Functional Magnetic Resonance Imaging, Ct Scan
Document Summary
Computed tomography (ct scan): computer controlled x-rays of the brain. Mri: uses radio waves and magnetic fields to produce a detailed image of the brain. Functional mri (fmri): measures brain activity by detected changes associated with blood flow(can sense brain movement) Eeg: records the brain wave patterns produced by electrical activity of the surface of the brain. Why do all these tests: not for diagnosis. Relays messages between the cerebellum and the cortex. Controls how much info is going up from the hindbrain to the midbrain (controlling arousal and attention) Cingulate cortex: primary cortical component of the limbic system, involved in emotional and cognitive processing. Amygdala: influences our motivation, emotional control, fear response, and interpretations of nonverbal emotional expressions. Thalamus: part of the forebrain that relays information from sensory organs to the cerebral cortex. Hippocampus: plays a role in our learning, memory, and ability to compare sensory to expectations.
