The Middle Temporal Area Does Not Relay Vestibular Signals

Résumé

The primate brain middle temporal (MT) and medial superior temporal (MST) areas have an intriguing relationship. It is conventionally thought that MT neurons respond to retinal motion stimuli (Born and Bradley, 2005), whereas MST cells respond both to retinal and extraretinal inputs (Assad and Maunsell, 1995). Area MST can be divided into two functionally distinct parts, namely the dorsal subdivision (MSTd) and the lateral subdivision. Both subdivisions are sensitive to visual motion signals and both receive vestibular input. Neurons in MSTd respond to self-motion, such as rotation, even in the absence of significant visual input (Takahashi et al., 2007). The integration of visual and vestibular information by MSTd is essential for real-world navigation, in which the interplay between object motion, optic flow, and self-motion can produce potentially ambiguous signals (Warren and Rushton, 2009).
