Lecture 7 Notes from Jenny's Friend Slides 10:  Dark Blue-Limbic system—very important when it comes to emotions  How close the hippocampus and the amygdala are to one another  Flashbulb memories—have to do partially with a particular emotion.  Eye witness that are experiencing extreme stress have trouble recalling the memory Slides 11:  B-olfactory tract—going out into the area where you receive information about smells from your environment  Smell is important when it comes to attachment relationships (especially for newborns)  E-Thalamus—sensory integration-take independent pieces of sensory information to integrate it. Sends the info to the limbic systems and the higher parts of the brain (for more analytical and critical thinking)  Allowing the amygdala and limbic system to respond quickly Slides 12:  appraising sensory information  Looking for threats  Looking to see if there’s a threat. Tells the limbic system that suggests there is a problem. Necessitates the LS to respond with a behavioral sequence to deal with the issue  Sort of like the ER doctor. Makes a quick diagnosis. Is there a problem? If so, it alerts the LS (sort of like a team of nurses). o Unconsciously appraises situations o Attack or avoidance response o Will tell the LS the best approach of action Slides 13:  If the amygdala detects something that is a threat, it is the LS that will lead to the whole experience of fear  Even if you don’t have an amygdala, you will still be able to appraise situations (slower though)  Thalamus is also informing the higher order systems Slides 14:  23:00  Ability to initiate, inhibit them, and the ability to modulate (change from one state to another)  Things that are coming about due to the way that we feel  Make us put a happy face because it’s demanded of us in a certain situation  Specific physiological responses to a situation-PC helps you calm down and regulate your feelings  neocortex- system complex enough to allow you to enjoy your misery o acts on a conscious level o acts slowly Slides 16:  only interested in the basic needs of the organism—interested in keeping you alive  (physical threats to your body) o good at detecting threats (core of one’s concern for self-preservation)  Specialized that are detecting threats that are social as well as social rewards Slides 17: (1) -Is it likely that there is a threat or reward in my environment?  react to a face that is depicting fear Slides 18:  better able to detect rewards when they are social (a) disgust—you don’t need a social context. (b)Arrogance, flirtatiousness- You are not flirting with someone that is not there Slides 19:  The amygdala is necessary for labeling basic emotions, but for some reason it is specialized for labeling socially complex emotions  no foundation to understand basics? Slides 20:  Both positions assume that the amygdala is trying to determine if something is good or bad (valence)  Intensity judgment-how good or how bad is a particular stimulus  If the amygdala is able to judge intensity, then that shows breaking down the world into finer
