Method and system for generating sensory data onto the human neural cortex
US 6536440 B1

Abstract

A non-invasive system and process for projecting sensory data onto the human neural cortex is provided. The system includes a primary transducer array and a secondary transducer array. The primary transducer array acts as a coherent signal source, and the secondary transducer array acts as a controllable diffraction pattern that focuses energy onto the neural cortex in a desired pattern. In addition, the pattern of energy is constructed such that each portion projected into the neural cortex may be individually pulsed at low frequency. This low frequency pulsing is formed by controlling the phase differences between the emitted energy of the elements of primary and secondary transducer arrays.

 A non-invasive system for projecting sensory data in a part of a human brain, the system comprising:

a primary transducer array configured to emit acoustic energy as a coherent signal source toward the human brain;

a secondary transducer array positioned between the primary transducer array and the human brain; and

a sensory data processing system coupled to the secondary transducer array, wherein the sensory data processing system sends an acoustical pattern signal to the secondary transducer array, the secondary transducer array producing a diffraction pattern for the emitted energy from the primary transducer array, the diffraction pattern altering neural firing timing in the brain.
