‘Striosome’ Neurons in the Basal Ganglia Play Key Role in Learning

A new study sheds light on the role striosomal neurons play in reinforcement learning.

An image of green poison ivy leaves with "summer" under the image is positioned above an image of red and orange poison ivy leaves with "fall and spring" under it. Both of these images are to the left of a graphic of a brain with the striatum and hippocampus drawn in and labeled. Areas are labeled with the words avoid, red, leaflets, shiny, and summer on the graphic.
