People who struggle with mathematics could be helped by using electrodes to “excite” certain areas of the brain, a study has suggested.
Test subjects were asked to do sums while being exposed to high-frequency, random electrical noise stimulation, also called tRNS.
The team, from the universities of Surrey and Oxford, Loughborough University and Radboud University in the Netherlands, sent a mild electrical current to the brain through two electrodes on the scalp
“What we have found is how this promising neurostimulation works and under which conditions the stimulation protocol is most effective,” said Prof Roi Cohen Kadosh, head of the school of psychology at the University of Surrey.
“This discovery could not only pave the way for a more tailored approach in a person’s learning journey but also shed light on the optimal timing and duration of its application.”
Test subjects were split into four groups, including a learning group and an overlearning group – in which people practised maths “beyond the point of mastery” while being exposed to tRNS.
The other two groups were exposed to a placebo, which researchers said was similar to real stimulation but without significant electrical currents.
Brain activity was measured via an electroencephalogram (EEG) recording at the start and end of the stimulation.
The team found the ability of those whose brains were less “excited” by maths during the assessment had improved after stimulation.
“Previously, we have shown that a person’s ability to learn is associated with neuronal excitation in their brains,” said Prof Cohen Kadosh.
“What we wanted to discover in this case is if our novel stimulation protocol could boost, in other words excite, this activity and improve mathematical skills.”
There was no change in those who performed well in the initial assessment, or in those included in the placebo groups.
The study, published in the journal Plos Biology, used 102 people and assessed their mathematical skills beforehand.
Tips to stay safe during hot weather
- Stay hydrated: Drink plenty of fluids, especially water. Avoid alcohol and caffeine, which can increase dehydration.
- Seek cool environments: Use air conditioning, fans, or visit community spaces with climate control.
- Limit outdoor activities: Avoid strenuous activity during peak heat. If outside, seek shade and wear a wide-brimmed hat.
- Dress appropriately: Wear lightweight, loose and light-coloured clothing to facilitate heat loss.
- Check on vulnerable people: Regularly check in on elderly neighbours, young children and those with health conditions.
- Home adaptations: Use blinds or curtains to block sunlight, avoid using ovens or stoves, and ventilate living spaces during cooler hours.
- Recognise heat illness: Learn the signs of heat exhaustion and heat stroke (dizziness, confusion, rapid pulse, nausea), and seek medical attention if symptoms occur.

Why your domicile status is important
Your UK residence status is assessed using the statutory residence test. While your residence status – ie where you live - is assessed every year, your domicile status is assessed over your lifetime.
Your domicile of origin generally comes from your parents and if your parents were not married, then it is decided by your father. Your domicile is generally the country your father considered his permanent home when you were born.
UK residents who have their permanent home ("domicile") outside the UK may not have to pay UK tax on foreign income. For example, they do not pay tax on foreign income or gains if they are less than £2,000 in the tax year and do not transfer that gain to a UK bank account.
A UK-domiciled person, however, is liable for UK tax on their worldwide income and gains when they are resident in the UK.
