CREATE
ARTIFICIAL
‘BRAIN’
A groundbreaking method
has enabled the study of
complex, living brain tissue
To simulate layers of
the brain’s neocortex,
the neurones were
laid down in layers.
Each layer has been
coloured differently
with a dye
he ultimate science
fiction B-movie conceit
is a fully functioning
brain in a jar. Now bioengineers
at Tufts University, Boston, have
brought the idea closer to reality
after creating 3D brain-like tissue
and keeping it alive for more than
two months.
Until now researchers have
grown neurones in Petri dishes
for study. However, this method
can only produce growth in
two dimensions and so is
