Neurulation refers to this folding process whereby the neural plate is transformed into the neural tube, and this takes place during the fourth week.

Cranial and caudal neuropores become progressively smaller until they close completely (by day 26) forming the neural tube.

It is distinct from the mesoderm underneath the neural tube which is called the chordamesoderm that becomes the notochord.

Neural activity is constantly changing.

Some problems are good for neural nets we know that others, neural nets are hopeless on them.

It's actually a tube.

You have tube worms.

I took the tube.

And religion reconfigures our neural pathways.

This is what's called neural placicity.

And those are the neural structures.

These signals are called neural activity.

That was the neural firing rate.

And this sequence of neural activation is hypothesized to be the neural basis of those sequence of movements.

That's a fluorescent tube refined.

These are called tube worms.

This is an inorganic tube.

Trillions of neural connections have changed configuration.

And these are made of this kind of tube electricity tube, we call it in Holland.

Sixpence a small tube, and a shilling for the large tube, containing four times as much.

The neural plate will form opposite the primitive streak from ectodermal tissue which thickens and flattens into the neural plate.

These are neural connections that can be strengthened.

And over time, these neural pathways become hardwired.

Giant tube worms, 10 feet tall.

Test tube holders make it easier to hold test tubes. By using a holder, there is a safe distance between ones hand and the test tube when the tube is hot. Typically, test tube holders are used to hold test tubes over open flames.

If you, say, wanted to get from Regent's Park station to Great Portland Street, the Tube map would tell you take the Tube, go to Baker Street, change over, take another Tube.
