Crossmodal Links between Vision and Touch in Spatial Attention: A Computational Modelling Study
Figure 5
Exemplary temporal patterns of neuron responses to a visual target delivered either on one side or on the other side in condition D (a tactile cue of 30 milliseconds preceded any target stimulus; stimulus onset asynchrony = 90 milliseconds). Only the responses to a visual target are shown since, in condition D, responses on each side do not differ significantly across modalities. Panel (a) displays the response of neurons in the cued side to a visual target on that side. Panel (b) displays the response of neurons in the uncued side to a visual target on that side. In each panel, the displayed curves are the time response of the unimodal neuron on which the target stimulus is centred, the time response of the bimodal neuron, and the time response of the inhibitory neuron. The blue vertical dashed line denotes the onset time of the target stimulus, maintained throughout the rest of the simulation.
