Microfluidic Localized Hydrogel Polymerization Enables Simultaneous Recording of Neural Activity and Behavior in .

Monitoring an animal's brain activity during motion provides a means to interpret the brain activity in the context of movement. However, it is challenging to obtain information about the animal's movement during neural imaging in the popular model organism due to its small size. Here, we present a microfluidic tool to immobilize only the head region of for simultaneous recording of neuronal activity and tail movement.
