Claim One:
1. An apparatus for recording neural activity, comprising: (a) a micro electrode array configured for application to a target tissue area of the brain for which neural activity is to be recorded, with said micro electrode array comprising a plurality of electrodes, arranged in at least a two dimensional array, with the electrodes positioned so that recorded signal information from adjacent electrodes overlap one another; (b) multiple sub-array active circuits, each sub-array active circuit electrically coupled to a plurality of the electrodes of the micro electrode array and which receives data and control signals for performing recording and stimulation; (c) a computer processor having data and control signal lines connected to said multiple sub-array active circuits for controlling stimulation of said micro electrode array and processing signals from said micro electrode array; and (d) a non-transitory memory storing instructions executable by the processor; (e) wherein said instructions, when executed by the computer processor, perform steps comprising: (i) determining a weighting matrix, which spans an area of multiple electrode positions surrounding a center electrode position, for the micro electrode array based on a given electrode configuration; (ii) collecting neural signals from the micro electrode array; (iii) applying the weighting matrix to a window of collected neural signals to generate a superposition signal for the center electrode and its boundary area of recording power density; (iv) moving the window of the weighting matrix for different center electrode positions within the micro electrode array; and (v) recording neural activity for multiple electrodes in the micro electrode array to which said weighting matrix is applied in the moving window.
