Brain stimulation shown to boost memory - study
Published in Saudi Press Agency on 05 - 11 - 2006


Stimulating the brain with gentle
electric currents during sleep boosts memory, German scientists
said on Sunday.
When they applied several currents that mimic natural slow
oscillating brain waves in sleep they enhanced the memory of
medical students who had done a word-learning task.
"It leads to improved memory retention," said Jan Born, a
neuroscientist at the University of Luebeck.
The scientists, whose results were published online by the
journal Nature, believe brain stimulation could help people with
memory problems and Alzheimer's disease.
"This is an alternative way to intensify or to improve sleep
and its memory function," Born told Reuters.
He and his team asked the students to learn a list of paired
words in a standard memory test before they fell asleep. The
researchers stimulated their brain while they slept. After they
woke up, the students had to recall the words they had
memorised.
If the currents were applied to the scalp during deep sleep,
the first few hours of nocturnal sleep, the students recalled a
greater number of words than if they had been given a sham brain
stimulation.
"This is proof that this slow oscillation has a real
function during sleep -- to build and consolidate memory," said
Born.
"It is an eight percent increase overall. This is a striking
increase," he added.
The students did not feel any sensation from the currents to
the frontal cortex of the brain or any adverse side effects. The
currents forced the brain more into the deep slow-wave sleep to
improve the memory function, according to the scientists.
Memory function in the medical students was already very
good before they received the brain stimulation but the currents
managed to improve it.
"There is growing evidence that you can very effectively
manipulate brain function by different types of electrical
simulation," Born said.
He believes the natural slow oscillations and those induced
by the electrical currents affect the hippocampus area of the
brain which plays a part in memory.
"The slow oscillations during slow-wave sleep trigger a kind
of replay of these memories in the hippocampus," he added.
The hippocampus is one of the first regions of the brain
that is damaged in patients with Alzheimer's disease, a
degenerative illness that robs people of their memory and
cognitive ability.
