We are excited that we will see everyone soon! We will use a hybrid format. If you are part of the on-campus Harvard community, we invite you to put on your mask and attend in person in the large lecture hall Northwest B103. If you prefer to join via Zoom, that will work, too. We will take questions from both groups.

However, testing whether these circuits indeed play a causal role requires targeted neural perturbation strategies that enable discrimination amongst competing models. Here we probed the role of macaque V4 and its primary feedforward target, the inferior temporal (IT) cortex, during object recognition. We combined DREADDs-based chemogenetic inhibition of V4 neurons with large-scale electrophysiology in V4 and IT while simultaneously measuring the monkeys' image-by-image object recognition behavior. Our results provide causal evidence linking the ventral stream hierarchy with core object recognition behavior. Also, in addition, to providing a “yes” vs. “no” answer to the involvement of a brain area in a behavior, we demonstrate how our approach allows us to use direct causal perturbation data to discriminate amongst competing mechanistic brain models.
