Title: John David Durrant: Innovator in Auditory Evoked Potentials
Introduction
John David Durrant is a notable inventor based in Allison Park, PA (US). He has made significant contributions to the field of auditory evoked potentials, particularly through his innovative patent. His work focuses on the analysis of brain electrical activity, which has implications for understanding auditory processing.
Latest Patents
Durrant holds a patent titled "Steady state measurement and analysis approach to profiling auditory evoked potentials from short-latency to long latency." This invention relates to methods and systems for profiling evoked potentials in brain electrical activity. It applies steady state response concepts to analyze longer latency responses that reflect activity in brain regions beyond the brainstem, extending to the cortex. The use of repeated stimuli within a single analysis window produces a quasi steady-state response, allowing for high-resolution spectral analysis. Response amplitudes are measured at repetition rates from 80 to below 1 Hz, utilizing trains of repeated tone-burst stimuli. An amplitude measure, defined as the harmonic sum, is incorporated into the spectral power of the response, which includes both the fundamental frequency and its harmonics. Additionally, time ensemble averaging can be employed to enhance the signal-to-noise ratio.
Career Highlights
Throughout his career, Durrant has worked with reputable organizations, including Intelligent Hearing Systems and the University of Pittsburgh. His experience in these institutions has contributed to his expertise in auditory research and innovation.
Collaborations
Durrant has collaborated with notable colleagues such as Abreena Iris Tlumak and Rafael E Delgado. These partnerships have further enriched his research and development efforts in the field of auditory evoked potentials.
