week 10- Final Neuroscience of Behavior Flashcards
What is the outcome of learning
memory
What are the four types of memory
Sensory memory, short term memory, working memory, long term memory
What are the three processing stages of memory
1: Encoding
a. acquisition
b. consolidation
2. Storage
3. Retrieval
What parts of the brain are involved with memory?
Many, The key ones are the
- Hippocampus-interconnected with many structures
- Amygdala
What is the loss of memory after a lesion?
anterograde/amnesia
What is the loss of memory of events that occur before a lesion?
retrograde
What case highlighted that memory is separate from perception and intellect?
- The Famous case of H.M.,
- we can still learn new motor, procedural and perceptual skills(perception and intellect intact) but can ‘t remember how(memory impaired)
What happened in the case of H.M.?
- loss medial temporal lobe and bilateral hippocampus
- He retained normal short-term and working memory and procedural memory but could not acquire long term memories
Sensory memory, echoic memory, iconic memory are all examples of ?
- Short-term memory
- lasts seconds to minutes
What do these stages describe? 1. sensory memory, 2. attentional resources move to short term storage
3. if rehearsed goest to long term memory
Short term memory modal model
What is working memory?
the ability to retain information over short term(maintenance) and perform mental operations of stored
Who proposed the phonological loop, visuospatial sketchpad and central executive?
Bradley and Hitch
What are aspects of long term memory?
DES/NP
- Declarative memory
- Episodic memory
- Semantic memory
- Nondeclarative memory
- Procedural memory(motor skills, walking, talking, riding bike)
What is the difference between declarative and non declarative memory
-Declarative memory is explicit, memory we have conscious access to
consists of episodic(personal experience and semantic(facts)
-Nondeclarative memory is implicit, can’t be declared
consist of priming, habituation, sensitization, procedural memory, learning motor, cognitive skill
What does Damasio say an emotion is?
action programs largely triggered by external stimuli
examples include disgust, fear, anger sadness, exploration and play, care of progeny and and attachment to mates
What are some the complex interconnected network neural systems involved in emotion?
- ANS ( all organ systems, hypothalamus, pituitary, hormones)
- Limbic system( orbitofrontal cortex and amygdala
- higher order sensory cortex
- amygdala
- insula
- mPFC (orbitofrontal cortex, ventral striatum, acc)
What some basic emotions?
anger, fear, disgust, sadness, surprise, happiness, pride and shame,
What are complex emotions?
- love jealousy,
- involves complex goal directed emotions
What are the 2 factors that make up complex emotions?
valence and arousal positive valence (approach) negative valence (withdrawal)
What is the Cannon-Bard Theory?
- bear-thalamus-cortex/fear and hypothalamus/emotional reaction/fight or flight
- you feel the fear and then you run
what is appraisal theory?
I’m out in the wilderness, and I’m not afraid of bears cause I’ve seen them before
-emotional processing is an interpretive act
What is the James Lange theory
- opposite of cannon bard
- bear-run-feel fear
What is the Singer-Schacter theory?
- when ever something happens, we have to put causative agent to it
- study: those unaware they had been injected with adrenaline attribute feelings to the environment
Do facial expressions vary culture to culture?
Ekman found that it did not
name Universal basic emotions
Anger, fear, disgust, sadness, surprise, happiness, shame
-innate universal short lived
What is constructivist theory?
cognition emerges from cognition molded by culture
What are the three components of emotions
- physiological response
- behavioral response
- subjective feeling
What is the most connected structure of forebrain
amygdala
What is critical for fear based learning?
amygdala
What modulates arousal in relation to memory and enhances retention and modulates hipppocampal consolidation
amygdala
Who recognized that emotions were critical to decision making
Damasio
What did the Devised Iowa Gambling Task Find?
- damaged brains, can’t recognize emotions, its focused on high payouts without looking at the risks
- physiological is needed to guide the feedback
- inability to asses and make good decisions
If S.M can’t recognize fear then where is the damage in the brain?
amygdala
What is the key to recognizing fear if one can’t recognize fear in a face?
eye contact
What is active in categorization of people into groups/ racial stereotyping?
amygdala
Is emotional regulation better in those with R frontal lobe or L frontal lobe?
L frontal lobe
Does suppression and reappraisal of emotion expression boost or diminish SNS activity
boosts
What is the heartiest way to deal with negative emotions
reappraise, refrain it
- not express or repress
- ranting and raving will do no good, BP will just raise up, will/James, bumps up the actual emotion
- ex: consuming a friend who was dumped»reframe, give perspective, be more objective
- emotion study’s heuristic is wrong
If one thinks a situation will get better will the amygdala activity increase or be down regulated?
down regulated
What is key to the appraisal and modulation process of emotions?
PFC and ACC
What is the key to experience emotion?
insula, involved in modulation of emotion
-
What does insula do?
- active when experiencing emotions both at physical and emotional level
- its the junction for the integration of cognitive and emotional information
What is central to life according to Damasio
-maintain homeostasis
What’s Damask’s theory with feelings and evolution?
- feelings developed to respond to homeostatic imbalances, provide additional level behavior regulation
What’s Damask’s theory with feelings and evolution?
- feelings developed to respond to homeostatic imbalances, provide additional level behavior regulation
What are the mechanisms of Damask’s theory of feelings and evolution?
- feelings arise from older regions of the brain
- rooted in events in single cells, unmyelinated axons conveying humoral and visceral information
What are Damask’s two main types of action programs?
- Drives: instinctual needs
- Emotion: triggered by exteroceptive stimuli
What is the most prominent interoceptive pathway in the brainstem?
- lamina 1 spinothalamocortical pathway
- vagus nerve
What is the most prominent interoceptive pathway in the brainstem?
- lamina 1 spinothalamocortical pathway
- vagus nerve
What leads to locked-in syndrome?
-damage to upper half of brainstem
Is the insult required in processing of feelings?
- no
- but engaged in processing feelings
- key role in modulation of body states
What structure constitutes half of the frontal lobes in humans
the prefrontal cortex
lateral prefrontal cortex (LPFC), frontal polar
region (FP), orbitofrontal cortex (OFC) and medial frontal
cortex (MFC) are part of what structure?
the prefrontal cortex
What is the impact of Frontal lobe damage
Discussion of perseveration, apathy, and
impulsivity as common problems. Poor planning,
decision making, lack of consideration of
consequences, poor self organization and social
awareness
What is an example of Habit defined as an action no longer under the
control of a reward?
- Brushing your teeth because it feels good
- eating junk food
- smoking
What is the anterior -posterior gradient?
anterior- problem solving
the more ancient structures are in the back
What is the key nt for rewards?
Dopamine
Is the Sugar high a true phenomenon?
No, sugar does not cause hyperactivity. When we eat sugary foods, large amounts of dopamine are released, creating this “sugar high”.
What’s a better way to describe multitasking?
Multitasking is really just rapid switching: How does
this make sense given the most basic truism
regarding attention?
What does the PFC do in rapid switching?
- modulate sound
- modulate visual processing
What is activated to inhibit long term memory?
PFC

- 3 good things exercise
- signature strengths inventory: what are the things i do well
- ones that did the best were the strengths group and the 3 good things group
What is Pennebakbr’s theory
- we need to vent, and make sense about a problem
- studied 3 groups, one group wrote about current life, second group wrote about stressful event, third group wrote about past and 1/3 reported sexual trauma
- when third group did this intervention they had 50% drop in doctor visits, BP/HR dropped below previous norms

- past
- how impact now
- how does this tie together
