How does the brain handle long-term stress?
People differ enormously as to what they consider to be stressful and how they respond to it. In general, short periods of moderate stress can actually be a good thing for the brain.
BrainFacts/SfN
When are children’s brains viewed as “adult brains”?
There is no magical age at which brain development suddenly stops. The brain is constantly changing, even in adulthood and old age.
BrainFacts/SfN
How much can a person learn in a lifetime?
The amount of information the brain can store in its many trillions of synapses is not infinite, but it is large enough that the amount we can learn is not limited by the brain’s storage capacity.
BrainFacts/SfN
Is every dementia the same as Alzheimer's disease?
Dementia is a description of any progressive disorder that takes away a person’s cognitive and functional abilities.
BrainFacts/SfN
What does it mean to have synesthesia?
Synesthesia is a condition in which stimulation of one sense automatically evokes a perception in an unstimulated sense.
BrainFacts/SfN
Why do some people toss and turn during sleep if your body is "paralyzed" to keep you from reenacting dreams?
Tossing and turning generally occurs during very brief arousals from sleep during the night.
BrainFacts/SfN
How does the brain handle multitasking?
When two tasks demand competing attention, there is generally a switching that occurs between the neural processes involved, rather than concurrent processing as may be expected with true multitasking.
BrainFacts/SfN
What is brain plasticity, and can it help relieve psychiatric or degenerative brain disorders?
Brain plasticity (from the Greek word ‘plastos’ meaning molded) refers to the extraordinary ability of the brain to modify its own structure and function following changes within the body or in the external environment.
BrainFacts/SfN
What is transcranial magnetic stimulation, and what is it used for?
Transcranial magnetic stimulation (TMS) is a method for electrically stimulating the brain from the outside of the skull.
BrainFacts/SfN
Do cell phones cause brain cancer?
Over the past two decades there have been many studies aimed at detecting a risk of brain cancer associated with cell phone use.
