Sample | Early Delay | Saccade Late | Delay | |
---|---|---|---|---|
Category only | 39/53 (74%) | 36/53 (68%) | 10/53 (19%) | 5/53 (9%) |
Saccade only | 0/53 (0%) | 0/53 (0%) | 12/53 (23%) | 9/53 (17%) |
Category and saccade | 3/53 (6%) | 1/53 (2%) | 20/53 (38%) | 37/53 (70%) |
Nonselective | 11/53 (21%) | 16/53 (30%) | 11/53 (21%) | 2/53 (4%) |
Category eta-squared (mean) | 0.20 (max: 0.69) | 0.16 (max: 0.50) | 0.10 (max: 0.38) | 0.14 (max: 0.59) |
Saccade eta-equared (mean) | 0.01 (max: 0.06) | 0.01 (max: 0.04) | 0.13 (max: 0.39) | 0.20 (max: 0.78) |
The numbers and percentages of neurons selective for category and saccade factors in each task epoch are shown. Significance was determined by a two-way ANOVA with category and saccade condition as factors (p < 0.01). Eta-squared values (which indicate the fraction of variability explained by each factor) were computed for each neuron. Mean eta-squared values across the population (excluding nonselective neurons in each epoch) are reported along with the maximum value (in parentheses) observed across neurons in each task epoch.
