Researchers from the University of Basel have now shown in a study that regular caffeine intake can change the gray matter of the brain. The researchers observed changes in the gray matter, as they report in the journal Cerebral Cortex.
What chemical does caffeine replace in the brain?
In your brain, caffeine is the quintessential mimic of a neurochemical called adenosine. Adenosine is produced by neurons throughout the day as they fire, and as more of it is produced, the more your nervous system ratchets down.
Does caffeine affect brain long term?
The authors say that effects of caffeine can build up over time and lead to measurable changes in the brain: If you’re blocking adenosine receptors with caffeine over the long term, this can result in “adaptive changes and lead to chronic alterations of receptor expression and availability,” the authors write.
What part of the brain is affected by caffeine?
Our data showed that caffeine reduced CBF in the whole brain but increased BEN across the cerebral cortex with the highest increase in lateral prefrontal cortex, the default mode network (DMN), visual cortex, and motor network, consistent with the beneficial effects of caffeine (such as vigilance and attention) on …
How long does it take for the brain to recover from caffeine?
Most Caffeine addiction symptoms can be resolved in 7-12 days of consumption reduction. During that period, the brain will naturally decrease the number of adenosine receptors on each cell in response to the sudden lack of Caffeine.
Does caffeine deplete serotonin?
Chronic caffeine intake has been shown to increase the receptors of serotonin (26-30% increase), GABA (65% increase), and acetylcholine (40-50%). This may contribute to the elevated mood and perceived increase in energy we feel after a coffee (which makes espresso a handy pre-workout drink).
What are the long term side effects of caffeine?

Does caffeine affect dopamine?
Caffeine makes the brain more sensitive to dopamine, but it doesn’t actually increase levels of the chemical in the brain.
