Task 4 Reward and Value update to lOFC +MCC (Striatum + drug addiction
…

Spike activity increase for CS = proportional to value of expected reward
Spike activity increase for Reward/US = depends on error prediction / how expected the reward was :D !! #
Spike activity increase for CS = proportional to value of expected reward
Spike activity increase for Reward/US = depends on error prediction / how expected the reward was :D !! #
:!:Knowledge about what type of reward to expect, biases brain areas / dopa activity in response to reward
- money = nucleus accumbens more active (cause more extrinsic motivation)
- cognitive reward = less activity in nucleus accumbens (cause more intrinsic motivation) # #
VMS = motivation phase, feedback of cocain = required
--> after few weeks
DLS = doesn't need feedback from cocain anymore for it to engage reward seeking behavior (can be seen by dopa inhibition study where it becomes habit (but really this study no evidence for that just that sensory motor = important for drug habit they say but no evidence in this study but they cited other study :P !! so yeah haha) [#]
-----> they say DLS = regulates automaticity of drug taking / reward seeking :3 !!(#bbe994) #
Fun fact VMS = core of the Nucleus accumbens :o !!! (cool for task 3 :D!!) #
