Abstract

A prosthetic visual or aural sensing system has light or sound sensing means 10 providing a sequence of electrical signals, a store 18 to store the signals, read means 17, 19, 20, 21 for reading out the stored information in a sequence which differs from the write sequence, and an implant including electrodes 37 contacting the brain cortex and means to stimulate electrodes 37 sequentially in dependence on the signals read from store 18. The read/write sequence difference is provided by a PROM 21 controlling the write or read address sequence of store 18 and allows non-critical positioning of electrodes 37 since it can be programmed to stimulate the most appropriate electrodes so that a coherent picture is produced. Sensor 10 and electrodes 37 may each comprise a matrix of from 256 to 5000 elements. Data signals, power, and clock pulses may be coupled to the implant inductively. Sensing means 10 may be provided by a hand camera or built into spectacles or implanted. The video data fed to store 18 may define only black or white levels, or also intermediate grey levels. <IMAGE>
