Paragraph 2
The diagram of the fly's brain's
pathways looks like a scientific work of
. It is a stunning,
web of neurons. The diagram is known as a connectome. To create it, the
sliced the fruit fly brain into 7,000 microscopic slivers. Each of these was studied using an electron
that imaged cells that were four-millionths of a millimetre
. The researchers classified more than 8,400 different cell
. If the neural pathways were unravelled, they would stretch for 150 metres. The human brain has 86 billion neurons and trillions of
. Current
could not create a connectome of our brain. That map is still
away.
