How Caffeine Affects Neurotransmitters and Profoundly Changes Your Brain What caffeine does is to block the adenosine receptors (specifically the A1 receptors making it an A1 antagonist) by mimicking adenosine, thus preventing them from detecting the real stuff. In other words, caffeine renders the adenosine inert, making us feel more awake and alert as a result.lutamate is one such ‘excitatory’ neurotransmitter which has an important role in ‘long-term potentiation’. What this means, is that glutamate increases the strength of the connection between neurons that fire at the same time.
