Brain stimulation might enhance mathematical abilities according to recent research findings.
In a groundbreaking study, researchers at the University of Oxford have employed Transcranial Random Noise Stimulation (tRNS) to enhance the brain's capacity to learn math more efficiently. This non-invasive brain stimulation technique, which targets specific brain regions, has shown significant potential in improving math skills, particularly for those who struggle in the subject[1][2][3].
The study focused on the dorsolateral prefrontal cortex (dlPFC) and the posterior parietal cortex, two brain regions crucial for learning, memory, and problem-solving. By improving the connectivity between these areas, tRNS allows for more efficient processing of mathematical information[1][3].
The mechanism behind tRNS's improvement involves enhancing neural connectivity, modulating neurochemicals, and increasing neuroplasticity. By benefiting individuals with weaker natural brain connectivity, tRNS allows for more efficient processing of mathematical information[1][3]. Learning gains have also been linked to lower levels of GABA, an inhibitory neurotransmitter that affects learning capacity. Reducing GABA levels can enhance neuroplasticity, allowing the brain to adapt and learn more effectively[1][5].
The potential implications for education are significant. tRNS could be a valuable tool in addressing math learning disparities by providing targeted interventions for individuals with weaker brain connectivity, thereby reducing educational inequality[1][3]. As a non-invasive and painless method, tRNS could potentially be more accessible and cost-effective compared to other interventions, making it a viable option for educational settings[5].
However, while tRNS shows promise, further research is needed to fully understand its long-term effects and to integrate it effectively into educational systems. The study, published in PLoS, suggests that we might be able to change the brain itself to help people learn better, particularly those who are least proficient in math[1].
The experiment, which lasted for five days and included math challenges involving both calculation and memorization, involved 72 students who wore caps fitted with electrodes and received mild, painless electrical currents over specific brain areas[1]. The study found that students with weaker brain connections who received stimulation over their prefrontal cortex made a significant improvement of 25-29% in math skills[1].
tRNS might especially help people whose brains aren't wired for fast math learning. Traditional education approaches to fix these gaps have focused on better teaching, but this study suggests that biology plays a significant role. The math skill gap affects jobs, income, health, and trust in society, making it crucial to address this issue effectively[6].
Integrating insights from psychology, neuroscience, and education could help more people reach their potential and reduce long-term inequalities. However, experts caution that we don't fully understand how consumer-grade brain-stimulators interact with individual brain shapes and chemistry. As research progresses, tRNS could revolutionise the way we approach math education, helping to close the gap and create a more equal learning environment for all.
