Visual and other sensory perceptions are a result of multiple coordinated neuronal activities in the brain. To understand these “neuronal routes”, it is important to record or create a map of the brain while the brain is active and working. Researchers at Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University have developed a cranial window for visualizing and mapping neuronal traffic to understand how the sensory pathways work.
The conventional cranial window: A cranial window can be created by thinning or removing a piece of the skull. A blood flow imaging technique allows to track oxygen in the blood by measuring the active and inactive areas of the brain in response to various external stimuli. The disadvantage of this method is reduced stability in an awake, pulsing brain, and removal of a piece of the skull can have other detrimental effects.…
