Hippo Optics is a high precision measurement tool that achieves the optical resolution necessary to stimulate individual neurons in vitro. An array of 120 electrodes collect the signals that are generated, which are then mapped onto Hippo Optics, allowing spatial and temporal awareness. Hippo Optics integrates seamlessly into the lab setting, connecting directly into a computer. The interface allows users to specify the position of initial optical stimulation and records the consequent electrical reactions of surrounding neurons. This allows optogeneticists to study how neurons communicate with each other by considering the source of stimulation and following the reactions as time progresses.
