The paper measures hue perception asymmetries using visual evoked potentials and behavioral tasks, finding stronger responses for hues near yellow compared to blue.

The paper investigates early neural responses to color associations of familiar objects, finding that shape can trigger color-specific responses before actual color processing.

This study uses fMRI to show that anomalous trichromats have reduced chromatic responses in early visual cortex but normal responses in later areas, indicating neural compensation for color deficiency.

The paper investigates whether visual categorization is graded or all-or-none in the human brain using EEG and behavioral measures, finding all-or-none responses despite graded neural amplitudes.
