Research project

New methods for assessing the control of blood flow in the brain

Staff

Lead researcher

Professor David Simpson

Prof of Biomedical Signal Processing

Research interests

  • His research interests are in biomedical signal processing with applications in neurophysiology and cardio-vascular and cerebro-vascular control. Specific topics are:
  • Blood flow control in the brain (how does the brain regulate is own blood supply and how to detect impairment of this function).
  • Auditory evoked potentials (methods to detect the small electrical responses of the brain to auditory stimulation for the assessment of various hearing disorders).

Collaborating research institutes, centres and groups

Signal Processing Audio and Hearing Group

Our aims are to understand and develop technological innovation in complex signaling and human acoustics.
