Hi everyone
Just a reminder that we have guest speaker Dr Vincent Costa giving a talk
at YNiC this afternoon at 4pm, followed by refreshments. This promises to
be an interesting session, and we encourage you all to attend:
-
*Title: *More than a feeling: A comparison of amygdala and ventral striatum
contributions to reinforcement learning
*Abstract:* If you ask a neuroscientist about emotion, they would probably
give you the skinny about every amygdala study ever written. If you ask
them about reward, they would probably give you a syllabus filled with
references to the ventral striatum. But I’ll bet they can’t tell you what
specific computations are computed in the amygdala relative to the ventral
striatum. This is because traditional views of reinforcement learning have
held that the striatum integrates dopaminergic reward prediction errors to
facilitate learning, but have not ascribed a specific role for the
amygdala. After decades of research suggesting the amygdala mainly
contributes to emotion and simpler forms of associative learning,
researchers are just beginning to explore the computational boundaries of
amygdala function. The emerging perspective, which I will discuss, is that
standard accounts of reinforcement learning that emphasize stratal and
cortical contributions, should be revised to include a key role for the
amygdala.
Hope to see you there!
Kind regards
Lauren
