Putative human LIP equivalent as assessed with fMRI (Koyama et al. 2004). (A) The oculomotor task consisted of horizontal saccades in response to the shift of the fixation target. Upper row: horizontal target displacement. Lower rows: eye movement recordings in horizontal and vertical direction. (B) BOLD signal associated with saccades in monkeys. Increased neural activity is found in the lateral wall of IPS (left image: coronal section; right image: horizontal section). (C) BOLD signal associated with saccades in humans. Increased neural activity is found in the medial wall of IPS (horizontal section). (D) Saccade-related activity superimposed on 3D renderings of a macaque brain (left) and a human brain (right). Monkey area LIP is situated in lateral IPS, the putative human LIP equivalent is located in medial aspects of posterior IPS. (Adapted from Koyama et al. 2004, with kind permission.)
