Extended Data Figure 7: Model for characterizing the alignment of neural activity to different task events in the SMT.

Grey traces, PSTHs across trials, sorted by duration into five groups. The same traces are overlaid below (black or red). For each cell, the six subplots are for different values of the three parameters (αpress, αrelease, αfrequency) indicated in the corner of each subplot). For each subplot, PSTHs are plotted as a function of β, defined as 
where 
is the normalized time relative to the press of the joystick, 
is the normalized time relative to the release of the joystick, and 
is the normalized sound frequency (see Supplementary Methods for details). For each cell, the subplot with the strongest alignment of PSTHs across trials is emphasized by red traces.
