Abstract The neurotransmitter serotonin (5-HT) plays a central role in brain development,
regulation of mood, stress reactivity and risk of psychiatric disorders, and thus alterations in …

Serotonin is known to play a role in brain development prior to the time it assumes its role as
a neurotransmitter in the mature brain. Serotonin regulates both the development of …

Brain serotonergic circuitries interact with other neurotransmitter systems on a multitude of
different molecular levels. In humans, as in other mammalian species, serotonin (5-HT) …

Neurotransmitters are released from neurons and mediate neuronal communication.
Neuromodulators can also be released from other cells and influence the neuronal …

Serotonin (5-hydroxytryptamine, 5-HT), the “happy hormone,” has a phylogenetically ancient
role in neural transmission (Turlejski, 1996). Because the serotonergic system has a …

The use of the artificial sweetener, aspartame, has long been contemplated and studied by
various researchers, and people are concerned about its negative effects. Aspartame is …

Background: Neurotransmitters such as monoamines appear in the embryo before the
neurones are differentiated. They may have other functions than neurotransmission during …

Brain monoamines, and serotonin in particular, have repeatedly been shown to be linked to
different psychiatric conditions such as depression, anxiety, antisocial behaviour, and …

The hypothesis explored in this review is that the high levels of serotonin in the blood seen
in some autistic children (the so-called hyperserotonemia of autism) may lead to some of the …

Abstract Development passes through sensitive periods, during which plasticity allows for
genetic and environmental factors to exert indelible influence on the maturation of the …
