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.
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.
Impairments in the production of neurotransmitters may lead to depression in some patients, preliminary results show, opening new avenues for research.
