Many people have consumed caffeine in some sort of way, whether its through coffee, soda or chocolate. However, many of us do not know that it is a highly addictive stimulant. Caffeine is good for increasing alertness, happiness, energy and increased task performance. It does this by stimulating the central nervous system and directly affecting the body’s metabolism. However, having too much caffeine can cause problems such as, but not limited to, insomnia, irregular heart rhythms, dehydration, and headaches. The article being examined, “Separating neural and vascular effects of caffeine using simultaneous EEG-fMRI: Differential effects of caffeine on cognitive and sensorimotor brain responses,” was published in NeuroImage in 2012, focuses …show more content…

The researchers had to interpret their findings with warning. As for the visual task, there was no significant effect for caffeine in the occipital electrodes. However, there was a shorten latency in the auditory oddball task which is linked to the improvements in task performance. The shorten latency suggests that caffeine is responsible for the neuroexcitatory action on brain areas involved in attention and decision-making functions, which was observed with the behavioral results of this task (Diukova 2012). The findings from this study are relevant to the field of clinical neuroscience because the methodology of using EEG and fMRI was able to show regions such as the superior frontal gyrus, which is responsible for self-awareness; in addition, it was able to show the left sensorimotor cortex, which is responsible for much higher cognitive function. This methodology could come in great use for pharmacological and/or disease studies in the future. In addition, having these types of technology can help us advance our knowledge and research of the affects of caffeine on the brain, as well as many other
