Nat Neurosci: Science has found that electrical stimulation through the scalp can improve a person's memory

People's memory ability weakens with age, how can it help people, especially the elderly, improve their memory?

In a study published Aug.

Brain networks and regions have their own pulses of electrical activity, and brain cells use electrical impulses to communicate with

Corresponding author Robert Reinhart of Boston University and colleagues collaborated on improving these two types of memory in 150 subjects aged 65-88 years: When subjects heard and immediately recalled a list of 5 20 words, the researchers used electrodes embedded in their hats to transmit an electric current

To determine whether this approach can improve memory, the researchers turned to a form of brain stimulation called transcranial alternating current stimulation (tACS), a non-invasive method of stimulating the brain by transmitting electrical current through electrodes on the surface of the scalp

The researchers used a new form of tACS that can target specific small areas

The trial recruited 150 volunteers, aged between 65 and 88, and the volunteers were divided into 3 groups

Based on previous research, they targeted two specific brain regions with two different stimulation

The authors argue that further research is needed in the future to determine whether these effects can last more than a month, and whether these specific methods can also enhance memory function

But when the frequency of transformation (i.

"I was deeply impressed and surprised by this paper," said

Hanslmayr added that there are a few factors that make this study unique

There are a few more questions

He added that the team is also expanding this work and investigating whether tACS can help people with conditions like Alzheimer's disease, as the study suggests that brain stimulation may bring the greatest benefits

Metz Xiaobian saw this research and thought of Chinese acupuncture, acupuncture, especially the stimulation of electric needles, which is quite similar to this, through electric needle stimulation, may also be able to improve memory, this study is more scientific and reasonable
