Researchers uncover novel neurotransmitter system in the brain

Neurotransmitters are chemicals that transmit signals between neurons or from neurons to other cells. They interact with specific receptors found in the brain of humans and animals, controlling a variety of biological processes, e.g. fear, anger, pleasure, memory, energy, appetite and sleep.

Study analyzes the effect of maternal smoking on newborns’ body size and proportion

Although quitting smoking during the 1st trimester of pregnancy reduces the risk of low birth weight, it isn't enough to protect the unborn child from being born shorter and with smaller brain size, a new study from the University of Eastern Finland shows.
