The analysis of two small studies by the Neuromodulation Research Facility suggests that habitual caffeine consumption may impede the brain’s ability to undergo plasticity, challenging assumptions about caffeine’s role in promoting neural adaptability. The research, involving 20 participants, indicates that individuals who abstain from caffeine exhibit stronger long-term potentiation effects, crucial for information assimilation and neural adaptation. However, caution is warranted due to the study’s limited sample size and self-reported caffeine dosages. Further, well-controlled studies are needed to elucidate the precise impact of caffeine on plasticity.
