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.
Abstract
Our findings provide direct functional evidence of tonotopic organization within the bVM, supporting its role as an auditory relay and its contribution to fine auditory discrimination.
