Dr Joseph Sollini
Appointment
  • Research Associate
  • The Ear Institute
  • Faculty of Brain Sciences
Research Summary
Joseph's work focusses on sound segragation processing in auditory cortex.  Specifically this work aims to understand how the brain is able to rapidly aquire the statisics of a background or target sound to aid sound segregation.  During his PhD he probed the relationship between spectral content and spatial location, demonstrating increasing frequency difference increased the ability of auditory cortex to treat sound location independently.  This was not true at the level of inferior colliculus suggesting this segregation mechanism is applied just before or in the auditory cortex.

During Joseph's first post-doc (at Imperial College London with Dr Paul Chadderton) he demonstrated the role of prior exposure to a sound background enhances subsequent detection of a target sound in that background.  Optogenetic manipulation demonstrated this "build-up" to the properties of the background required auditory cortex.  He also demonstrated that auditory cortex can use simple receptive field properties, such as frequency tuning to sound onset and offset, to build complex receptive fields to more abstract sound properties (such as frequency sweep direction).

Joseph's current work (UCL Ear Institute  with Dr Jennifer Bizley) focusses on speech segregation in auditory cortex.  In addition, to contiuning work on the investigating the mechanisms of stimulus build-up to backgrounds.
