  "text": "What resolves this contention: Mechanistic account of mouse ALM persistent activity: discrete attractor dynamics with stable end points (paper A) versus a sequential feedforward-amplification motif in which selectivity propagates through transiently amplified directions before collapsing to a choice state (paper B). The two models predict different geometries of the population trajectory and different sensitivities to small-amplitude perturbations along early task-irrelevant directions. / We show that during the delay epoch, the activity of ALM neurons moved towards discrete end points that correspond to specific movement directions. / Choice selectivity grew as it flowed through a sequence of directions in activity space.",
