Annual Review of Neuroscience, 1996
Synaptic vesicle exocytosis is rapid and highly localized, which are features that arise from the organization of the presynaptic active zone, where vesicle fusion occurs. Colocalization of calcium channels with the proteins making up the vesicle docking machinery at the active zone, combined with the low affinity and high cooperativity of the calcium ...

Synaptic assembly of the brain in the absence of neurotransmitter secretion.
Science, 2000Brain function requires precisely orchestrated connectivity between neurons. Establishment of these connections is believed to require signals secreted from outgrowing axons, followed by synapse formation between selected neurons.

Neurotransmitters in the retina
Current Eye Research, 1996Processing of visual information within the retina depends in large measure upon a complement of chemical neurotransmitters which are released at synaptic contacts between individual neurons. Numerous investigators have participated in the identification of many of these transmitters and their assignment to specific neuronal subpopulations. However, it

Neurotransmitters as morphogens
1988Publisher Summary This chapter presents considerable evidence for morphogenetic functions of neurotransmitters during embryonic development, a role that may derive from their appearance early in evolution, still evidenced today by their presence in primitive organisms.

Homeostatic control of presynaptic neurotransmitter release.
Annual Review of Physiology, 2015It is well established that the active properties of nerve and muscle cells are stabilized by homeostatic signaling systems. In organisms ranging from Drosophila to humans, neurons restore baseline function in the continued presence of destabilizing ...

Neurotransmitters in the cerebellum
2001An overview is given of the neurotransmitters of the intrinsic and afferent fiber systems of the cerebellar cortex, with emphasis on recent immunocytochemical data. As in other brain regions, the fast excitation and inhibition appear to be mediated mainly by glutamate and GABA, respectively. However, some fiber systems are heterogeneous with respect to

Archives of General Psychiatry, 1982
The most predictable anxiolytic effects of neurotransmitters are linked to the activation of a gamma-aminobutyric acid (GABA)-ergic subsystem associated with specific benzodiazepine receptors. Recent studies have indicated that subtypes of benzodiazepine receptors may be associated specifically with anxiolytic actions.

During early development, neurotransmitters are important stimulants for the development of the central nervous system. Although the development of different neuronal cell types during early zebrafish (Danio rerio) development is well-studied, little is ...

Biofeedback and Self-Regulation, 1990
In this article definitions of stress and distress are proposed and the relationships between stress and activities of neurohormonal systems explored. The idea is developed that stress is a condition where expectations--whether genetically programmed, established by prior learning, or deduced from circumstances--do not match the current or anticipated ...

Historically, 3,4-dihydroxyphenylalanine (DOPA) has been considered to be an inert amino acid that alleviates the symptoms of Parkinson's disease by its conversion to dopamine via the enzyme aromatic L-amino acid decarboxylase. In contrast to this generally accepted idea, we propose that DOPA itself is a neurotransmitter and/or neuromodulator in ...
