Eight low-dimensional components, each containing a neuron factor (left column), temporal factor (middle column), and trial factor (right column), are shown from a 15-component model. For each component, the trial factor is color-coded by the task variable it is most highly correlated with. These eight components were chosen to illustrate six factors that were modulated by the six meta-data labels (see legend) as well as factors #3 and #4, which demonstrate novel structure. The remaining seven components are shown in Figure S4. Blue dashed lines (bottom right) denote reward contingency shifts.
