Synapses in the mouse neocortex can release multiple packages of neurotransmitters, suggesting that connection strength is more flexible than previously thought.

In a first-of-its-kind study, researchers monitored subsecond changes in levels of the neurotransmitters in the human brain, unlocking new insight into their function.

Clues about the biological mechanisms that contribute to a person’s chance of contemplating or attempting suicide

The biochemical mechanisms in the brain underlying suicidal behavior are beginning to come to light, and researchers hope they could one day lead to better treatment and prevention strategies.

Inhibiting nerve cells that produce the neurotransmitter made it harder for baby mice to recover from bouts of slowed breathing.

Male rodents exposed to nicotine had changes in sperm genome methylation and produced pups and grandpups with abnormal behavior.

Researchers have identified what makes synapses strong or weak in fruit flies.

Host slugs given Prozac to increase their serotonin levels no longer avoid parasitic nematodes, the same behavior seen in infected slugs.

Researchers unveil the neural basis of alertness in larval zebrafish.
