In Brief
Where Caffeine Hits the Brain
For the first time now, scientists from the Forschungszentrum Jülich research centre were able to demonstrate that the invigorating effect of caffeine predominantly affects the highly developed regions of the cerebrum. By way of an imaging marker and the method of positron emission tomography (PET), the researchers have shown that caffeine blocks out adenosine, a ‘tired maker’, from specific nerve cell receptors. This results in activation of the nerve cells and hence in triggering of cognitive processes. Knowledge about this mechanism can constitute an important step towards the prevention and treatment of both Parkinson's and Alzheimer's disease. Studies have shown that regular consumption of caffeine reduces the risk of developing these diseases.
