AmygdalaCurrent Lecture- Primary Sensory Cortexo RTPJ- higher area associated with making moral decisions (i.e. to what degree do we hold someone accountable for their judgments; social judgment, sense of self)- Broca’s Aphasia o Broca’s area (left frontal)o Inability to produce coherent speech, but understands what he’s being askedo Ability to translate coherent response to produce speecho Governs language production, ability to articulate language is impaired- PFCo Planning, aggressiono Algorithms- Sensory HomunculusThese 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.o Large hands, large lips (lots of sensory from cortex up here) Pic of weird body shows neural representations in the braino Tiny upper arm, tiny chest, stomach- Temporal Lobeo Auditory cortexo Hippocampus (emo memory) and amygdala (emo fear and aggression) in deep layerso Wernicke’s area Wernicke’s aphasia- Beneath the Cortexo Forebrain: Cerebral cortex (cerebrum) Limbic system (limbic= border between higher cortex of brain)- Overall limbic system =emotional responses (hard to convey and explain why)- Cingulate Gyrus- wraps around corpus callosum, cortex, key limbicstructure, - Anterior Singular Cortex- emotional research, immoral brain, empathy; part of prefrontal cortex, catching errors, experiencing pain, negative emotional experience towards a painful stimulus- Hippocampus- o Heart of emotional experienceo Deep layers of temporal lobe: cannot see from the outsideo Plays a key role in the “consolidation” of declarative memories: verbal, spatial (move to new place, start building map in head of where you are and how to get to places)o Episodic (first person narrative, episodes of life)o Semantic- general knowledge about the world, facts)o Damage: anterograde amnesia (forward looking, inability to form new long term memories)o Basis of date rape drug- powerfully suppress the neural activity in hippocampus (transient episodic failure)o “The sea horse”- Amygdala- “the almond”o Attribution of “emotional valence”: can make associated stimuli “HOT” or “COLD”o The Fear Factor ? Electrical stimulation marked fearful behaviors. Intact functioning necessary for fear conditioning. Kulver-Bucy Syndrome: no fear? (monkey’s found that abnormal lack of fear response, loose fear response to snakes, fire; loose appreciation for social hierarchy and won’t show correct responses to superiors/peers)o Emotional significance attributor: how much you need to direct attention/recognize stimulus Basal ganglia Thalamus
