Our remarkable capacity for imagination requires complex neural networks.
-
Does this brain appear to be rotating? Rapid, involuntary eye movements paired with sharp contrast patterns in an image may cause the brain to perceive motion where there is none.
-
Do lost connections between brain regions guarantee impaired function? Imaging techniques show normal functional activity in people with missing links, spurring scientists to say: not necessarily.
-
Have you ever wondered what life would be like without the sense of smell? Learn more about a rare condition called congenital anosmia and how the brain processes smell.
-
How do nerve cells in the brain influence their neighbors?
-
The brain uses some unconventional means to communicate.
-
Much faster than a traditional MRI, MEG can be used to provide even more information about brain activity.
-
Optical imaging relies on shining weak lasers through the skull to visualize brain activity. These techniques are inexpensive and relatively portable. They are also silent and safe: Because only extremely weak lasers are used, these methods can be used to study everyone, even infants.
-
PET is one of the most important techniques for measuring blood flow or energy consumption in the brain. This method of measuring brain function is based on the detection of radioactivity emitted when positrons, positively charged particles, undergo radioactive decay in the brain.
-
Insulation covering wires preserves the strength of the electrical signals that travel through them. The myelin sheath covering axons serves a similar purpose.
