Fast, Flexible Closed-Loop Feedback: Tracking Movement in "Real-Millisecond-Time".

One of the principal functions of the brain is to control movement and rapidly adapt behavior to a changing external environment. Over the last decades our ability to monitor activity in the brain, manipulate it while also manipulating the environment the animal moves through, has been tackled with increasing sophistication. However, our ability to track the movement of the animal in real time has not kept pace.

Neuronal Responses to Conspecifics in the Ventral CA1.

Conspecific recognition and discrimination is a vital aspect of social interactions. Genetic manipulations have implicated the CA2 sub-field and ventral hippocampus in rodent social memory. However, little is known about the nature of hippocampal responses to social signals.
