The Dynamic Brain

Speaker
Professor Peter Robinson (Double Australian Research Council Federation Fellow)

The brain’s activity varies around the clock in response to stimuli, light inputs, and the build-up and clearance of sleep-promoting chemicals – somnogens. Signatures of brain activity have been observed for over a century and are widely used to probe brain function and disorders, often via the electroencephalogram (EEG) recorded by electrodes on the scalp, or through functional magnetic resonance imaging (fMRI), which measures a combination of blood volume and deoxygenation.

Learn more about a quantitative physiologically based model of the working brain is described that responds correctly to the day-night cycle, somnogens, caffeine and pharmaceuticals, and generates activity in the cortex consistent with brain imaging measurements. Successful applications to numerous experiments are described, including EEGs, seizures, sleep deprivation and recovery, fatigue, and shift work. Aside from its scientific uses, this working brain model is currently finding clinical and industrial applications to brain function measurement and to prediction and monitoring of alertness.
