“…This also defines hippocampus-PPC-PFC function. Perception is shaped by learning, memory, expectation, and attention (Bernstein,2010;Gregory,1987), processes which the hippocampus-PPC-PFC is engaged in (Sieb, 2013(Sieb, ,2015. Perception also has features conditioned by the hippocampus-PPC-PFC: constancy (the ability to recognise the same event from widely varying sensory inputs-Atkinson, Atkinson & Smith,1990;Bernstein,2010), grouping (humans naturally perceive events as organized sets of qualia- Banerjee,1994;Goldstein,2009;Gray,2006;Weiten,1998;Wolfe et al,2008), contrast (perceived qualia can be affected by the qualities of context- Corsini,2002;Kushner,2008;Popper,2010), experience (with experience, organisms can learn to make finer perceptual distinctions and learn new kinds of categorization-Sumner,2015), motivation (Block & Yuker,2002;Coon & Mitterer,2008;Sieb,2013;Weiten,2010), and expectation (a predisposition to perceive things in a certain way- Coon & Mitterer,2008;Hardy & Heyes,1999;Sieb,2013;Sonderegger,1998;Weiten,2010).…”
