  • Patent number: 9705239
    Abstract: A flexible electrode assembly comprises a central portion having electrical contacts disposed thereon and a plurality of elongated portions extending radially outwards from the central portion. One or more of the elongated portions has an electrode disposed in the vicinity of a distal end thereof. The electrodes are electrically coupled to respective ones of the electrical contacts disposed on the central portion. An apparatus for measuring electrophysiological signals in a human or animal body that incorporates the flexible electrode assembly is also disclosed.

  • Patent number: 8075137
    Abstract: Disclosed herein is a method of producing a stimulus for electrophysiological assessment of a visual field. The method comprises the steps of: generating a pseudorandom sequence of elements selected from at least two different element types, wherein elements of the sequence are assigned equal time intervals; and displaying the pseudorandom sequence. Each element of a first element type is associated with a baseline value, the baseline value being constant throughout a respective assigned time interval. Each time interval assigned to an element of a second element type is divided into a plurality of portions, each successive portion being associated with a display value of the element, wherein display values associated with, adjacent portions differ from one another, and further wherein display values associated with at least two of the portions are different from the baseline value.

  • Publication number: 20110218456
    Abstract: For electrophysiological assessment of visual function using a head mounted stereo display (e.g. virtual reality goggles) for displaying a stimulus which is used to generate a retinal or cortical response. In particular, a method for objective electrophysiological assessment of visual function of at least one eye of a subject includes presenting a visual stimulus to at least one eye of the subject, recording at least one of a retinal response and, a cortical response generated as a result of the presenting; analyzing said response and, as a result of said analyzing, forming a map of the visual function of the at least one eye of the subject 6. The invention also relates to as system for such electrophysiological assessment.

  • Publication number: 20030158497
    Abstract: This invention relates to the electrophysiological assessment of visual function using a head mounted stereo display (eg virtual reality goggles) for displaying a stimulus which is used to generate a retinal or cortical response. In particular, the invention relates to a method for objective electrophysiological assessment of visual function of at least one eye of a patient, which method comprises presenting a visual stimulus to at least one eye of the patient, recording at least one resultant response, selected from the group consisting of a retinal response and a cortical response, generated as a result of the presenting; analysing said response; and as a result of said analysing, forming a map of the visual function of the at least one eye of the patient. The invention also relates to as system for such electrophysiological assessment.
