PSYC100 Lecture Notes - Lecture 5: Dopamine Receptor, Locus Coeruleus, Melatonin
Document Summary
Ct (computerised tomography) scan, mri (magnetic resonance imaging) Advantages: measures electrical activity/analysis of stages of cognitive processing: disadvantages: poor spatial resolution, pet (positron emissions tomography) tracks radioactive glucose. Advantages: good spatial resolution: disadvantages: poor temporal resolution/exposure to low levels of radioactivity. Hindbrain is an extension of the spinal cord contained inside the skull where nuclei control blood pressure, heart rate, breathing and other vital organs. Abnormalities linked to depression, adhd, ptsd, sleep disorders. Reflexes, co-ordinates movements: memory of procedural related movements. Regulates hunger, thirst, sex drive: direct link to endocrine system. Forebrain is the most highly developed part of the brain the most responsible for the most complex behaviour and mental life. Prosopagnosia difficulty identifying faces: wer(cid:374)i(cid:272)ke"s aphasia impairment in comprehension of speech and language. Inhibit drives and urges: motor cortex -voluntary movement. Integration of proprioceptive and visual information: hemispatial neglect-particularly right hemisphere damage (ignore left)
