Tongue motor cortex: The back door of the reward system

Abstract

In paragraph 3.5 of their article, the authors provide some information about the nonmotor properties of tongue motor cortex. As a complement to the interesting work of Bono et al. (2022), in this commentary we focus on this aspect by addressing the link of the tongue motor cortex to the reward system, and its relevance for emotion processing, social cognition and psychopathology via connections of tongue motor area with other brain structures.
