The Emotional Gatekeeper: A Computational Model of Attentional Selection and Suppression through the Pathway from the Amygdala to the Inhibitory Thalamic Reticular Nucleus
Fig 4
Rapid flexible modulation of attention by emotion.
Axis and subplot labels are as in Fig 3. A, Plan map. B, Salience map for appetitive (positive) stimuli. C, Salience map for aversive (negative) stimuli. D, E, F, Sensory map, including sensory cortex (D), sensory TRN sector (E) and sensory thalamus (F). G, Input to sensory thalamus (stimuli and distractors). H, Reinforcement signals and Conditioned Stimuli (CSs). During the testing phases, the rate at which the plan (A) shifts from feed (blue) to fear (red) is dependent on the rate of build-up of the plan cortical expectation violation (EV) signal. Here the cortical expectation violation (EV) signal builds up rapidly in comparison with Fig 3, causing the plan to shift after a single expectation violation (A). The speed of resetting of cortical plan representations (A) determines how often there is a temporal window of opportunity for bottom-up emotion-related signals (green arrows, B and C) to determine plans (A) and sensory attention (D, F).
