A geometric representation unveils learning dynamics in primate neurons
Published in bioRxiv, 2019
To study neural dynamics during learning of new and diverse concepts, I trained two monkeys to perform the same classification task my human subjects carried and recorded neurons in the dACC and the Striatum as the animals learned eight novel classification rules. To examine dynamics, I developed a description of rules and neural representations of the visual stimuli that allowed tracking dynamics in geometrical terms - unifying sessions of learning different rules. This framework allowed teasing apart potential roles of the different brain areas and to predict future behavior from the neural state. Read more
