4/11/2023 0 Comments Ohsu soundsourceWe propose a model by which spatial encoding during cueing is inferred from the relative activity between the two hemispheres, and how spatial cueing is associated with repulsion of auditory space. We demonstrate excitatory neurons are the principal encoders of cue-modulation, and that spatial contrast between hemifields increase with task-engagement. We recorded more than 900 cortical units and show auditory responses to spatially mapping stimuli can broadly be classified as functionally inhibitory or excitatory to sounds. We present evidence of sound source spatial separation being reflected in behavioral reaction times. We trained two ferrets on a behavioral task involving spatially cued auditory attention. SoundSource is part of Oregon Health Sciences Universitys hearing services. to a hissing or white noise hum when there is no external sound source. Here we hypothesize that continuous mapping of auditory spatial responses during cued attention might reveal improved spatial tuning. of Otolarynology/Head and Neck Surgery in the OHSU School of Medicine. Our guarantee to you OHSU SoundSource guarantees we will act with integrity and treat all customers with respect. The goal of SoundSource is to help people of all ages hear for life. We provide total hearing solutions to enrich and enhance your listening experience. Additionally, auditory neurons show broad tuning which is surprising given the existing behavioral evidence of high spatial accuracy. OHSU SoundSource is dedicated to hearing. Normal spatial hearing is known to be dependent on auditory cortex, but how auditory cortex represents sound location is still a matter of debate. The ability to localize sounds have clear behavioral benefits. Elia Formisano (examinateur, Maastricht University)
