A team of scientists from the University of Lethbridge's Canadian Centre
for Behavioural Neuroscience (CCNB)
has confirmed the first ever successful example of brain cell re-growth in an adult rat.
This breakthrough may offer hope for effective treatments for
dementia-related diseases and conditions, such as
Alzheimer's, stroke, substance abuse, and the side effects of some cancer therapies where brain cells die.
The scientists explained that current research
on the reliability of a precise method to re-grow damaged cells in the hippocampus
and while successful in rats,
requires significant further research to be useful to humans in the future.
Sutherland said:
We took the approach that we should look for a simple way
to prove that cells can be re-grown and restore lost functions.
The hippocampus is very similar in rats and humans,
and generally is the part of the brain where cells governing memory die first,
or are affected by illness or injury.
Another important fact about this part of the hippocampus is
it has the ability to produce
a small number of new brain cells, even in adults,
so we knew that the process to make cell re-growth happen was there,
but was not able to be turned on or increased at will.

N.B.
The hippocampus is a seahorse-shaped area of the brain
which is responsible for short- and long-term memory.
