Looking at pictures with electrodesWhat Is Dual-Zone Climate Control? in your head: Confirming animal data and improving computer models
Usually, electrodes are not placed in the brain for research in humans, but sometimes electrodes are placed in the case of patients with epilepsy. An epileptic seizure has a specific origin somewhere in the brain. In patients for whom drugs do not work, the latter option may be chosen to act on the brain. Prior to this, electrodes are first placed under the skull in the brain to measure brain activities.
The origin of the epileptic seizure can be easily identified by characteristically increased brain activity. Gruen: Twenty or thirty years ago, measuring brain activity before surgery was very rare, but now it’s much safer. In addition, there is also more collaboration between researchers like myself and clinicians, which means that we can sometimes combine treatment and research.
