The paper investigates direct excitatory inputs from motor, somatosensory, and executive cortical areas to the auditory midbrain using optogenetics and electrical stimulation in anaesthetised rats.

This study shows that salicylate increases neuronal firing in the inferior colliculus via nitric oxide signaling, suggesting a central mechanism for tinnitus.

The paper identifies multiple non-auditory cortical regions that project to the auditory midbrain in rats, revealing a network involving sensory, motor, and prefrontal cortices.
