Single mode commutator

Simultaneous use of optogenetics or cellular/vascular imaging with pharmacological approaches in behaving rodents


In behaving animals, neurons can be manipulated and their neuronal activity/vascular network can be imaged  in a broad range of behavioral tests. A single or partially combined mode polyvalent commutator couples either optogenetics/pharmacological studies or cellular-vascular imaging/pharmacological approaches in behaving animals.

Because of the rapid connectivity and adjustments of optogenetics and pharmacological devices, several commutators can be used at the same time. We have developed a polymodal system combining several commutators to be used for on 10 adapted cages at a time.
