To decode brain signals
Every second, we are flooded by input from a multitude of sources: sight, sound and touch to name a few. In order to organize and efficiently process this constant avalanche of data, our brain is made up of approximately 100 billion nerve cells or neurons, which communicate via small electric impulses in order to properly decode this information. This remarkable effort is maintained by a constant supply of fresh blood which keeps the neurons well-nourished and prepared to quickly respond to the next task at hand.
How exactly does the brain achieve this delicate balance between neural activity and cerebral blood supply (neurovascular coupling)? How are disruptions in this balance related to diseases of the brain? These are some of the questions the investigator Kevin Whittingstall, Canada Research Chair in Neurovascular coupling, wants to answer.
The goal of Doctor Whittingstall’s research is to reliably detect even the most subtle changes in neurovascular coupling. For this, he and his colleagues are developing methods that can simultaneously track neural activity (fMRI) and blood flow (EEG) in the brain with great spatial and temporal precision. Importantly, these measures are non-invasive and can be safely repeated without any adverse effects to the individual.
The tools developed in doctor Whitingstall’s laboratory will help in better understanding how neurovascular coupling behaves in healthy brains, as well as how it is affected in patients with neurological disorders (e.g. brain tumours). In collaboration with neurosurgeons and neurologists, this will lead to safer and more accurate measures for the detection and treatment of neurological disorders in the brain.
