I read this article: https://news.mit.edu/2019/neurons-dendrite-role-computation-0606
My question is about this: “One hypothesis is that dendritic activity will actually sharpen up for representing features of a task you taught the animals, and all the other dendritic activity, and all the other somatic activity, is going to get dampened down in the rest of the cortical cells that are not involved,” Harnett says.
How exactly are neurons that are involved in a task chosen and how exactly is it decided which neurons are then supposed to be dampened?
Probably not a question that can be easily answered, but I wanted to ask it anyway.
