4. Non-invasive brain stimulation improves memoryScientists at Northwestern University have successfully used a non-invasive brain stimulation for the first time that can be used like a scalpel to make specific improvements in precise memory.
Memories are usually stored in the brain and “remembered” through a series of synapses that pass from neuron to neuron. If the strength of these synapses is weak, the brain starts to lose the ability to remember.
Using an MRI, scientists were able to determine where memory-related brain networks were located and stimulated them with non-invasive electromagnetic stimulation. The brain stimulation lasted 24 hours and correlated with brain activity changes.
This non-invasive stimulation gives scientists a better understanding of memory improvement. Previous brain stimulation only lasted a short amount of time and have short-lived effects on thinking abilities.
