1. A system for signal processing, comprising: a selection circuitry that receives data sets sampled at different time from voxels recorded from magnetic resonance imaging (MRI) of a subject and selects a plurality of data units from each data set that corresponds to regions of interests in the data set; and a coordination detection circuitry including (i) a plurality of channels and (ii) a spiking neural network comprising a plurality of neurons, each channel coupled to a corresponding neuron of the spiking neural network, the coordination detection circuitry receives, via the channels and spiking neural network, the selected data units corresponding to the regions of interests over time, each neuron of the spiking neural network generating a train of spikes based on the received data units over time, the coordination detection circuitry detects a coordination of the regions of interests including the neurons over time, classifies an activity of the subject based on activities of the neurons including at least trains of spikes that are fed back to the spiking neural network for recursively driving the neurons in the spiking neural network, and detects a brain injury of the subject based on the classified activity.
