- Inhibitory luminopsins are able to both acutely suppress and delay epileptic discharges in the rat hippocampus.
- Simultaneous inhibition of the DG and ANT was more effective at suppressing behavioral seizures than inhibition of either structure alone.
- Luminopsins offer a non-invasive means for cell-type specific optogenetic manipulation of network-wide activity.
Although optogenetic techniques have proven to be invaluable for manipulating and understanding complex neural dynamics over the past decade, they still face practical and translational challenges in targeting networks involving multiple, large, or difficult-to-illuminate areas of the brain. We utilized inhibitory luminopsins to simultaneously inhibit the dentate gyrus and anterior nucleus of the thalamus of the rat brain in a hardware-independent and cell-type specific manner. This approach was more effective at suppressing behavioral seizures than inhibition of the individual structures in a rat model of epilepsy. In addition to elucidating mechanisms of seizure suppression never directly demonstrated before, this work also illustrates how precise multi-focal control of pathological circuits can be advantageous for the treatment and understanding of disorders involving broad neural circuits such as epilepsy.
