If you inject a CaMk promoter controlled or D1-cre dependent virus into PFC, you get anterograde viral transport AND frequently infect D1 expressing cells in striosomes in medial striatum (red). This is a D1-Cre mouse with a cre dependent AAV9 virus. CaMK is less selective.

Nice work, but what about PrL cortex to DM striosomes vs M1 projections to matrix? Maybe that’s coming… www.science.org/doi/pdf/10.1...

Cannabinoid receptors in basket cell axons surrounding a hippocampal pyramidal cell. The CB1 receptor is presynaptic and expressed at high levels on GABAergic axons. Not necessarily ‘excitatory’ for the PC. It’s the oscillations!

Addition to the oddities of transgenics: When breeding NR2A knockouts back in the day, they would have seizures upon introduction. They recovered quickly and resumed the task, but weren’t great breeders or mothers. (Thinking of those of you forced to cull your mice. They have no idea…)

Useful information for those new to mice. See Jax Labs for more excellent information on all things mouse.
