Fig. 5: Gain control.
From: Sub-optimal modulation of gain by the cognitive control system in young adults with early psychosis
Gain-mediated relationships between stimulus responses in the visual cortex (inputs, x axes) and task responses in the AI (outputs, y axes) using beta estimates extracted from interference > baseline and neutral > baseline t-contrasts. Top row A, B shows parameter estimates extracted from SPM contrasts in VC and AI for neutral (blue lines) and interference (red lines) conditions, with line of best fit across participants. Middle and lower rows show local (C, D) and global (E, F) sigmoid-shaped activation functions, whose local tangents yield the state-dependent input-output gain functions.
