Timeline for experimental protocols.

Timeline	Animal procedures
Day 0	NeuRet-MSCV-Cre lentiviral vectors injection into the right cuneiform nucleus (CnF)
3–7 days after 1st viral injection	AAV-EF1α-DIO-hChR2 (H134R)-FP injection into the right deeper layers of superior colliculus (dSC)
4–8 weeks after 2nd viral injection	Bilateral lesion of amygdala by ibotenic acid injection
3–6 days after amygdala lesion	Optic fiber implantation on the right dSC
5–31 days after optic fiber implantation	Behavior testing induced by optogenetic stimulation of the right dSC (> 6 weeks after NeuRet-MSCV-Cre lentiviral vectors injection and > 1 week after bilateral lesion of amygdala)
