A study from the University of Surrey shows that transcranial Random Noise Stimulation (tRNS) can significantly improve math abilities in young adults with lower brain connectivity. This non-invasive method could be a promising solution for individuals at risk of falling behind in mathematics.
Participants who received tRNS on the dorsolateral prefrontal cortex (dlPFC) performed better during a five-day math training compared to those who received a placebo or stimulation in other brain regions. The improvements were particularly notable in individuals with lower pre-existing connectivity between key brain regions involved in learning.
The study also noted a link between success in learning and lower levels of GABA, a neurotransmitter that influences learning ability. These results support the use of brain-based interventions to address learning gaps in mathematics and reduce inequalities.
