Picture this: the prince has won his way past the dragon, past the huge walls of briars. He paces slowly through the sleeping castle, toward the tower where the princess lies, in a deep, deep sleep.
New study finds it's not just dopamine-producing cells, but likely ones that secrete norepinephrine, as well, that kick-start the movement disorder
Chronic stress makes people sick. But how? And how might we prevent those ill effects?
Seeing your life pass before you and the light at the end of the tunnel, can be explained by new research on abnormal functioning of dopamine and oxygen flow
The U.S. government raises a red flag about a potentially dangerous chemical in plastics--and Canada announces it will ban it
Study shows that sleep deprivation leads to a rewiring of the brain's emotional circuitry
It’s Halloween. You’re listening to some creepy, scary music. Maybe it sounds like something like this* – SCARY! You are lying still, attending to the emotional qualities of the music.
It is now known to cause developmental problems, weight gain and neurodegeneration
The male and female responses to stress are biologically different. What does that mean for treating PTSD, depression and other disorders?
Two decades ago it was discovered that the brain has "pleasure centers." These centers are now seen as belonging to a system of pathways that appear to play a role in learning and memory
Light and deep sleep differ physiologically, deep sleep having much in common with being awake. Studies with cats now suggest that the two states of sleep are induced by different biochemical secretions
Nerve cells communicate by secreting neurotransmitters. These chemical messages are translated by "second messengers" within the cell into transient and longer-lasting physiological actions
Chemical messengers mediate long-range hormonal communication and short-range communication between nerve cells. The two systems differ in directness, but some messenger molecules are common to both
What can we learn about consciousness from anesthetized patients?
By studying the brain's physical processes, scientists are seeking clues about how the subjective inner life of the mind arises
The search for biological underpinnings of depression is intensifying. Emerging findings promise to yield better therapies for a disorder that too often proves fatal
Biologists finally are unraveling the medical mysteries of migraine, from aura to pain
Late in life the human brain suffers attrition of certain neurons and undergoes chemical alterations. Yet for many people, these changes do not add up to a noticeable decline in intelligence
