In class we discussed the paper, “Optogenetics enables functional analysis of human embryonic stem cell-derived grafts in a Parkinson’s disease model”. The figures below come from that paper. (FYI: Halorhodopsin-EYFP is the same thing as eNpHR3.0-EYFP) Match each panel (A, B, and C) with the mouse genotype that could be responsible for the data.

Loss-of-function mutations in the SCN2A gene will most likely cause autism/intellectual disability. 1) 1) This type of mutation will most likely [decrease] neuronal excitability. 2) If an individual with this type of mutation develops seizures, does it make sense to treat them with a sodium channel blocker? [no]
