We also utilise a number of optical methods including single cell imaging and photo - activated
ion channels such as Channelrhodopsins.
The basis of this technique is to genetically modify neurons to express light - sensitive
ion channels such as excitatory channelrhodopsin or inhibitory halorhodospin and then use light to control the on / off status of neuronal excitation.
