During epileptic seizures, the brain’s excitatory neurons go haywire, generating extreme amounts of electric activity. There are already electronic devices available that help to prevent and mitigate seizures, but so far they’re only effective in some patients while having all the downsides of a serious implantation.
The graphene flakes that the team used are less than a micrometer (one millionth of a meter) in size, and it was shown that they are able to interfere with signals passing through excitatory neural synaptic junctions.
