FIGURE 8.
Superior colliculus neurons retained object values even after long periods without training. (A) Comparison between value-coding measured by value discrimination score (ordinate) and days since the last training of object values shown by log scale (abscissa). Each dot indicates each value-coding neuron for a set of objects. Red and black dots indicate significant value-coding (p < 0.05) and non-significant value-coding (p > 0.05), respectively. For linear regression, Pearson’s correlation ‘r’ and significance ‘p’ are shown. (B) Average value discrimination score for sets with different retention periods. Error bars: SEM.
