Auditory perceptual maps in humans and mice share common structures and predict perceptual decisions in discrimination learning (opens in new tab)

To efficiently perceive sensory information and guide behavior, the brain organizes incoming sensory stimuli into internal maps that capture perceptual relatedness between stimuli. Whether these maps, typically assessed in scaling paradigms without feedback, also shape perceptual decisions during reinforcement-based conditions remains unclear. Here, we assess task-naïve perceptual maps from similarity judgments of pulsed sound stimuli, and compare them to perceptual maps obtained from multipl...
