NeuralAct is a tool to visualize cortical activity on a 3D model of the cortex. It runs under Matlab, is stable, robust, and well documented.
To visualize neural activations, NeuralAct takes as input the 3D coordinates of the recording sensors, a cortical model in the same coordinate system, and the activation data to be visualized at each sensor. It then aligns the sensor coordinates with the cortical model, convolves the activation data with a spatial kernel, and renders the resulting activations in color on the cortical model. NeuralAct can plot cortical activations of an individual subject as well as activations averaged over subjects. It is capable to render single images as well as activation videos.
