Scientist Developed A Method To Treat Brain Disorder Without Surgery

Treating a brain disorder is usually through surgery but Scientist have now found a way to treat brain disorder without surgery.

The closest method to non invasive brain treatment is Electrical brain stimulation. Electrical brain stimulation is a promising method with which to modulate neural excitability. It is a method that will so be made obsolete by a none invasive method known as Temporal interference (or TI).

Temporal Interference Could Be a To Treat Brain Disorder Without Surgery

Researchers at Imperial College London are developing a new method of brain stimulation which they hope could alleviate symptoms of neurological conditions such as Parkinson’s, without the need for surgery

Called temporal interference (or TI) the method uses varying electric fields of different frequencies to subtly ‘nudge’ brain activity

Temporal Interference is the brainchild of Dr. Nir Grossman , an Imperial scientist, who has won many awards,  he has won the prize at the 2018 Science & PINS Prize for Neuromodulation. The idea as a whole is simple and it requires applying small overlapping electric fields to the scalp. It also uses electric fields of different frequencies to subtly ‘nudge’ brain activity.

How It Works

Dr Nir Grossman

Dr Nir Grossman pictured) is investigating a new a new way to stimulate the brain which he hopes could offer an alternative for huge number of patients in need

When the electrodes with small current are attached to the scalp, it generates two electric fields with different frequencies. These electric fields are rapid enough to change the activity of brain cells. But when these fields intersect, the amplitude of their combined currents changes at a low frequency, and this can stimulate brain cells and subtly alter their activity.

According to Dr. Grossman, the technique could offer an alternative for a huge number of patients in need, without the need for surgery and the associated complications, or interfering with higher functions.

During the experiment of this technique on mice, scientists found that TI can target and stimulate cells in the hippocampus, a region deep in the brain which plays important roles in memory and cognition, without affecting the cortex. It can potentially alter the fields’ intersection point, thus changing the focus of the stimulation and potentially stimulating regions deep in the brain without affecting the surrounding brain areas.

Any Risk?

Dr Grossman said, “As TI uses well-known electrical fields and doesn’t require us to change the brain – chemically or genetically – like other methods, we hope this will speed up its clinical deployment.”

“This type of non-invasive stimulation could offer a huge benefit to a large number of patients in need of neural therapy.”
