Tonotopic organization in the basal region of the ventromedial nucleus of the thalamus revealed by fiber photometry recording

Key Points

• Tonotopic organization was revealed, showcasing the auditory relay capability of the ventromedial nucleus.
• Functional evidence supports the contribution of the ventromedial nucleus to fine auditory discrimination tasks.
• Fiber photometry recordings were employed to observe the tonotopic arrangement across auditory frequencies in the nucleus.
• Findings emphasize the importance of the ventromedial nucleus in processing auditory information, hinting at its broader role in sensory perception.
