Parkinsons is not enough dopamine in receptors, so you give them schiphrenia because dopamine is upped everywhere
|
|
What happens with drug usage over time>Why?
|
Worked really well for a while and then stopped working, tolerance mechanisms at synapse
Brain will try to get back to set point because it associates that with normal, so it erases receptors, brain is very plastic place-get a rebound effect |

is how you make the stimuli subliminal, fear followed by neutral
If you know what it is…it’s to late…amygdala’s message to us, we can’t process everything at an aware level |
|
What is the thalamus?
|
you sensory relay station, most go to the thalamus first, primary visual cortex lives there, neuron senses lines and orientation which can then get put into meaningful shapes.
|
|
What are association cortexes?
|
Association cortexes are next to primary and put stuff together
|
|
How are messages sent around the brain?
|
Why have a relay station, filtering it, thalamus is part of the filter, thalamus can send it in different directions, if something is coming at head your vision only sees that, do you need to know if brick or television, you need to duck, you also send a signal to get out of the way
|
|
What types of things does the brain automate?
|
Brain automates motor programs such as picking up on faces, we automates lots of things, most of emotional life goes on without our knowledge, after a while brain will take over, walking is complex you are exciting and inhibiting one at the same time, driving, stiatum knows this

|
Changes the rules, build confidence and change the rule, measures ability to shift your response set, how to do you react, a lot of people will stick with number, but you need to shift,
|
|
Where does cognition happen?
|
the brain
|
|
How does bottom up and top down work in the brain?
|
Amygdala-bottom up activity, activate and then tell cortex,
Top down-can regulate amygdala, you will be false alarming like crazy, if see snake in zoo amygdala will have the same reaction, but cortex will know you’re safe,Not responding to snake because of plexy glass is emotional regulation |

PTSD and Panic-in normal brain its good thing that things go down, you don’t get this benefit if have panic, emotional processing gets equal weighting every second of the day
|
|
What does the sympathetic system? Parasympathetic
|
Sympathetic-brings up what you need in the moment, fight or flight, we have this system but stresses aren’t so acute, stays activated longer than it should
Parasympathetic-calming |
|
What is the HPA axis?
|
Hypothalamus-pituitary gland-adrenal gland (on top of kidney)
Adrenal gland releases adrenaline and steroids called cortisol Cortisol is an anti-inflammatory, release before get hit, swelling causes a lot of injury In long term they stay in the blood and drive things like the heart Cortisol inhibits the immune system If stays cronic you get health issues |

|
What is the two factor model of anxiety learning?
|
Place rat in two part chamber
Buzzer sounds - Rat shocked Rat can avoid shock by jumping to other side Rat jumps Rat learns to jump to buzzer Now turn shock off Rat continues to jump to turn buzzer off, Buzzer now the source of fear |
|
What kind of conditioning occurs with
the two factor model |
First, Pavlovian conditioning
rat associates buzzer with shock S-S Then, instrumental conditioning (operant) rat learns that avoidant behavior decreases anxiety S-R Will be more likely to perform that behavior in the future (habit) |
|
What happens in the two factor model with avoidance conditioning
|
Behaviors associated with decreasing anxiety can get quite complex
Back to the jumping rat Rat jumps - Buzzer off Now - Rat jumps - leave buzzer on until he presses a lever (no shock) Rat will eventually figure out how to turn off buzzer Can continually “chain” numerous behaviors together in order to turn off the buzzer ***What was originally all about the shock is now all about the buzzer Turning off buzzer is reinforcing Avoidance Conditioning |
