Summary
... In chapter 3 we investigated the relation between the coding of attention and reward in area V1 with a curve-tracing task where we varied the amounts of reward associated with the curves. Similar to previous studies (Platt & Glimcher 1999; Leon & Shadlen 1999; Ikeda & Hikosaka 2003; Sugrue et al 20 ...
