Sensory neuroscience is the study of how the brain processes sensory information, such as sight, sound, touch, etc. Some of the main aspects of our work are:
- Spike-based computation. The brain computes using precisely timed but discrete events called spikes. This mode of computation is different from both traditional analogue and digital computation, and presumably offers benefits compared to them. However, despite several interesting hypotheses and specific models, there is as yet not comprehensive theory of this form of computation.
- Auditory system. As we are interested in computation with precisely timed spikes, the auditory system is a natural one to study as the role of precise temporal information is so well established there.
- Realistic environments. We are interested in how sensory processing is done in realistic rather than laboratory environments. Specifically, rather than using simplified stimuli such as pure tones, we prefer to analyse the processing of complex stimuli such as natural sounds in a noisy background. We are also interested in the problem of processing a continuous stream of sensory data rather than the typical laboratory problem of responding to a brief, precisely delineated stimuli.
We are interested in both fundamental research into these problems, and applications in areas such as robotics and automatic speech recognition.
