“…Lisberger et al (1995) have recorded the responses of MT cells during target speeds and accelerations like those experienced during pursuit, so that much is currently known about this distributed representation of image motion. MT receives its visual inputs mainly from the primary visual cortex (V1) (Maunsell and Van Essen, 1983b) and provides visual inputs for pursuit via projections to a series of higher cortical areas (Ungerleider and Desimone, 1986;Tusa and Ungerleider, 1988;Boussaoud et al, 1992b;Tian and Lynch, 1996) that include the medial superior temporal area (MST) in the parietal cortex (Dürsteler and Wurtz, 1988) and the frontal pursuit area (FPA) in the depths of the arcuate sulcus (Lynch, 1987;MacAvoy et al, 1991). MT, MST, and FPA all project to the pontine nuclei (Glickstein et al, 1980;Ungerleider et al, 1984;Leichnitz, 1989;Boussaoud et al, 1992a), which in turn project to the parts of the cerebellum that are involved in pursuit (Brodal, 1979(Brodal, , 1982Gerrits and Voogd, 1989).…”
