# 293 — The logic of single-cell projections from visual cortex

Unsurprising: Neural projections from V1 aren’t random after all. And we can statistically verify that, if you please: If the probability of an axon projecting to area A is random and independent from the probability of the same axon projecting to area B, then $P(A) \times P(B) = P(A\cap B)$. But this does not hold, based upon the MAPseq data. So that’s neat.
