- claim_text
Mouse anterior lateral motor cortex (ALM) shows two discrete attractor end-points during delay-period persistent activity that are robust to transient optogenetic perturbations, with rare perturbation-induced switches producing predictable incorrect motor choices — direct in vivo support for a discrete (rather than continuous) attractor underlying motor planning.
