Arousal levels directly influence how the brain processes visual information. Researchers found that the firing patterns of neurons in the thalamus, a key relay station for visual signals, change in response to pupil dilation and constriction, indicators of arousal. This modulation of neural activity provides a mechanistic explanation for how our internal states shape our visual perception.
