Followup to see if this would help in stroke will not occur under current stroke leadership.

Working with animal models, Mexican
researchers have crossed the electroencephalic barrier, introduced a
nanogel to brain tissue and achieved the growth of neurons within the
gel, demonstrating a technique to promote regeneration of brain tissue.
After six years of research with materials engineering
and bioengineering, the first nanogel for neuron growthhas reached the
experimental stage and could be applied as a treatment for neurodegenerative diseases such as Alzheimer's and Parkinson's, in addition to its use during nuclear magnetic resonance or CAT scans to improve the visibility of the brain.
Dr. Victor Castaño, from the Centre of Applied Physics and Advanced
Technology (CFATA) of the National University of Mexico (UNAM) explained
that the nanogel is a biocompatible material that can be injected into
the brain and through external excitation promotes the spontaneous
growth of neurons.
"We wanted to improve and advance the generation of biomaterials for regenerating brain tissue.
During the experiments, we crossed the electroencephalic barrier that
keeps the brain isolated from the body; by crossing it, we could
introduce the nanogel, which then acted without harming the body. Within
the gel, neurons began to grow; this wouldn't have been possible in any
other way.
"Also, with the help of lase tweezers, we took two light phases and
stimulated the neuron by pulling it and putting it to exercise. This
gave us favorable results in increased neuronal tissue," explained Dr.
Castaño, member of the Commission of Biomedical Specialty, from the
Engineering Academy of Mexico (AIM).
The Ministry of Health reports that in Mexico more than 500 thousand
people suffer from Parkinson's and 850 thousand from Alzheimer's, both
neurodegenerative diseases that damage brain nerves.
