ANU researchers have developed a new device that could potentially unravel the mysteries of the left and right brain by measuring ear temperature.
The device, which may also have medical applications, offers scientists a cost-effective way of testing which side of the brain is active when performing different tasks. Scientists know that, depending on what kind of work the brain is doing, one side is likely to be more active - broadly speaking, language skills, for example, are handled by the left side of the brain and spatial questions are dealt with in the right - but brain scans can be an expensive research tool.
