“…Self-generated movements result in broad activation of most regions of the brain (Musall et al, 2019; Stringer et al, 2019), including some primary sensory areas like visual cortex (Keller et al, 2012; Saleem et al, 2013) where they have been shown to depend on visual context (Pakan et al, 2016). The framework of predictive processing postulates that in cortex, these movement related signals are internal model based predictions of the sensory consequences of movement that are compared to externally generated bottom-up input to compute prediction errors (Jiang and Rao, 2021; Keller and Mrsic-Flogel, 2018). Evidence for this interpretation has mainly come from the discovery of movement related prediction error responses in a variety of different cortical regions and species (Attinger et al, 2017; Audette et al, 2021; Ayaz et al, 2019; Eliades and Wang, 2008; Heindorf et al, 2018; Keller and Hahnloser, 2009; Keller et al, 2012; Stanley and Miall, 2007; Zmarz and Keller, 2016), and the observation that top-down inputs from motor areas of cortex appear to carry movement related predictions of sensory input to sensory areas of cortex (Audette et al, 2021; Leinweber et al, 2017).…”
