According to the passage, zones in the brain that were inactive before ----.
The loss of one sense encourages the development of the
four others. This has now been demonstrated convincingly
in a study by a team of doctors. During five days,
volunteers taking part in the study were blindfolded and
asked to carry out exercises designed to stimulate the
sense of touch. When their brains were then tested using
an MRI, an area of the visual cortex was shown to have
been activated as if, being underused, this area was
brought in to help the subjects when they had to rely on
touch. About 24 hours later, after the blindfolds came off,
the participants lost this aptitude. Previously, scientists had
always believed that the brain was organized into distinct
and highly-specialized systems. This new study, however,
shows that the human brain has the ability to reorganize
itself. In addition, the rapid reversibility of the process
suggests that it is not based on the creation of new
nervous connections but on the activation of previously
inhibited zones.
