WHAT ARE THE BRAIN AND BEHAVIOUR NON-INVASIVE TECHNIQUES?
In this article I will complete the topic
of the brain and behaviour in simple information.
(EEG) takes electrical recordings from the scalp. Small changes in electrical activity in the
brain are picked up by electrodes. The
changes are shown on a computer screen.
The changes in patters are often known as brain waves. EEGS are useful – they have found that we
have five stages of sleep, can help to detect epilepsy, damaged brain tissue
and tumours. EEGs also helped to identify the functions of the two hemispheres
of the brain. However, EEGs have largely
been replaced by brain scans.
Brain Scans can study cortical
functioning. They include –
CAT scans (computerised axial tomography) – An x-ray beam goes through an individual’s head and a level of radioactivity is detected. The level is lower when the X-ray passes through dense material. CAT scans are…
