We developed a biologically inspired model for detection and pursuit of small targets against complex backgrounds and tested it in a closed-loop flight arena. A winner-takes-all network of local feature detectors based on insect Small Target Motion Detector (STMD) neurons was used to direct the gaze of a camera mimicking the viewpoint of the pursuer in a(More)
OBJECTIVE Simultaneous electrical stimulation of multiple electrodes has shown promise in diversifying the responses that can be elicited by retinal prostheses compared to interleaved single electrode stimulation. However, the effects of interactions between electrodes are not well understood and clinical trials with simultaneous stimulation have produced(More)
OBJECTIVE Different frequency bands of the local field potential (LFP) have been shown to reflect neuronal activity occurring at varying cortical scales. As such, recordings of the LFP may offer a novel way to test the efficacy of neural prostheses and allow improvement of stimulation strategies via neural feedback. Here we use LFP measurements from visual(More)
Retinal implants for restoring partial vision to people with degenerative photoreceptor diseases consist of an array of electrodes implanted on the retina which can be driven according to images captured by a camera via stimulation electronics. In the past two decades this technology has progressed from prototypes, through clinical trials, through to the(More)
