Fitness variation across subtle environmental perturbations reveals local modularity and global pleiotropy of adaptation.

abstract：:The sequential activation of neurons has been observed in various areas of the brain, but in no case is the underlying network structure well understood. Here we examined the circuit anatomy of zebra finch HVC, a cortical region that generates sequences underlying the temporal progression of the song. We combined seri...
