Intro
Linear readout from a population
(1) demix dependencies on task parameters
Algorithm Step 1: decompose PSTHS into marginalized averages
Condition-independent components: Only part of manifold is experimentally controlled
Inter-area communication: theory
Inter-area communication: experiment
Simultaneous recordings in V1 output layers and V2 input layers of macaque
Population activity quantified as spike counts
Relating V1 population activity to response of a single V2 neuron
Predicting the V2 population Could predictive dimensions span a subspace?
Control: Is V2 activity lower dimensional than V1 activity?
V1-V2 interaction is low dimensional
Controls
Do predictive dimensions match dominant dimensions?
Predictive dimensions do not match dominant dimensions
prediction of target V1 activity relies on source V1 dominant modes
