A good fit
between the predicted rates (green traces) and the observed firing rates (red and blue traces) would indicate that activity locked to a particular
saccade can largely explain the firing rate changes seen in the cyclical task.
The difference
between this prediction and the observed firing rate for activity aligned to central
saccades indicates how well activity associated with peripheral
saccades can completely explain task - related modulations in activity.
(C and D) Binned correlations
between firing rate and current interval lengths for all intervals of the combined population, aligned to central
saccades (C) and peripheral
saccades (D).
For each
saccade, the burst magnitude was quantified from the raw data by counting all spikes in the time window
between the two tick marks (identifying
saccade onset an offset with a 20 ms lead time), and the resulting spike counts are displayed in the adjacent panels as running averages.
In addition,
saccades were evoked to a fixed series of targets across the visual field (R
between 2 — 35 deg, Φ ∈ [0,30,..., 360] deg; «rose scan»).
To dissociate
between these two possibilities, Figs. 7 and 8 show the measured burst profiles of two cells in for a series of large and small
saccades for which the cell fired the same number of spikes.
