Spatial Orientation Laboratory - University of Rochester

Research in this laboratory focuses on two areas of study.

1. We are interested in quantifying how human auditory, visual, and vestibular inputs interact in the processing of spatial localization and motion, as well as how spatial concordance is adaptively maintained across modalities. A variety of measures (physiological and psychophysical forms of "pointing") are employed, including a novel laser projection system and eye and/or head position monitors. Early experiments have demonstrated more accurate auditory localization capability than commonly reported, and unique attributes of visually modulated plasticity in human auditory spatial maps. We have also learned that ocular tracking of smoothly moving auditory targets is surprisingly robust, and can interact with vestibular signals much like visual targets can, implying similar smooth motion signals in central pathways. An applied area of interest is how these different sensory cues relevant to spatial location and motion deteriorate with aging.
2. We continue to study the spatial properties of the primate (including human) linear and angular vestibulo-ocular reflexes (VORs) and how they are controlled. Of particular interest is the characterization of adaptive plastic changes that occur whenever persistent mismatches are detected between reflex outcome (e.g. eye movements to maintain ocular fixation) and the sensory feedback the brain receives (image slip or error) during natural movement. Such conditions challenge the system during development, aging, and disease. An additional interest is how linear acceleration inputs of otolith origin are effectively parsed in order to distinguish head tilt relative to gravity from translational motion. This is crucial for the system to properly drive reflexes, behaviors, and perceptions relevant to these different interpretations of sensory input.

Qualifications include a PhD (or MD) with emphasis in neuroscience, biomedical engineering, biopsychology or related fields, and a facility with neurophysiologic and psychophysical methods.

Post-Doctoral Position Available Immediately in the Auditory Processing Laboratory

Applications are invited for a postdoctoral research scientist to join an active NIH-funded auditory neurophysiology laboratory at the University of Rochester. The successful candidate will use a multidisciplinary approach to study the organization and function of the anatomical pathways in the brain that are responsible for spatial hearing. Research expertise in electrophysiological, neuropharmacological, or computational approaches to brain function is desireable.

Interested candidates should send cover letter, curriculum vitae, and contact information for three references to:
