Crossmodal Links between Vision and Touch in Spatial Attention: A Computational Modelling Study
Figure 2
Exemplary network response to a visual target on one hand (the right hand) in basal conditions. Only the response to a visual target on one side is shown, since in condition A the network behaves in a similar way for targets on any side and modality. The target stimulus is maintained, from the onset time of application, throughout the entire simulation. Panel (a) shows network activity in steady-state conditions, that is, after the transient response to the stimulus has exhausted. The x and y axes of the unimodal areas represent the spatial coordinates of neurons RF center; the colour denotes the level of activation of the neurons. Panel (b) shows the temporal pattern of the activated neurons; the blue vertical dashed line indicates the onset time of the target stimulus. The left panel displays only the response of the visual neuron on which the stimulus is centred.
