Cerebral CortexCurrent Lecture- Agonists: Chemical that mimics the action of neurotransmitter. -“Mimic” neurotransmitters -Ex: cocaine stimulates dopamine receptors. - Antagonists: block neurotransmitters. -“Block” neurotransmitters. -Ex: antidepressants/ med for schizophrenia. - Medulla: sits at the spinal cord. Involuntary bodily functions. Breathing and heart rate. Basic survival. - Reticular Formation: Governs overall brain activity. Levels of conciseness and awareness. Damage=coma like symptoms.- Cerebellum: Voluntary muscle coordination and balance. Moving and coordination. - Thalamus: receives sensory information and sends it to other part of the brain for further processing. - Hypothalamus: Involves with appetitive behaviors. Hunger, thirst, aggression. -If you leason parts of it, it either makes you want obese or anorexic. (Prader- Willi Syndrome) Never get full. Rare genetic disorder. Borderline functioning brain capabilities. - Amygdala: involved with emotional experience and expression. Perception of threat. Damaged=docile, passive. Hyper oral. Ex: put a lot of things in their mouth. Autism and William syndrome. Kluver-Bucy syndrome- Hippocampus: acquisition and the consolidation of memory. Damaged = difficulty forming memory. Retaining in the moment. Cerebral Cortex: most advanced part of the brain.- Lobes:-Frontal: Creativity, higher order reasoning, problem solving. Personality, thinking flexibility. Problems with self-awareness. Disinhibited. Interpersonal stickiness. Logorrhea: keep talking and don’t get the social cues to stop talking. -Parietal Lobe: part of the brain that makes sense of sensory motor information. Complex movement. Damaged = apraxia: loss of ability to perform complex movements over and over again. Disconnection between the mind and the body. Ex: tying your shows. -Occipital: Processing, integration and interpretation of visual information. Final destination to vision. -Cortical blindnessAnton-Babinski Syndrome-Temporal: interpretation and procession of auditory information. Stuff that you
