Presynaptic Terminals
Research News and Information
Definition of 'Presynaptic Terminals'The distal terminations of axons which are specialized for the release of neurotransmitters. Also included are varicosities along the course of axons which have similar specializations and also release transmitters. Presynaptic terminals in both the central and peripheral nervous systems are included. Common names: Presynaptic Terminals; Presynaptic Terminal; Terminal, Presynaptic; Terminals, Presynaptic; Nerve Endings, Presynaptic; Ending, Presynaptic Nerve; Endings, Presynaptic Nerve; Nerve Ending, Presynaptic; Presynaptic Nerve Ending; Presynaptic Nerve Endings; Synaptic Terminals; Synaptic Terminal |

Extrasynaptic GABAA receptors: form, pharmacology, and function.
12 Oct 2009 
GABA is the principal inhibitory neurotransmitter in the CNS and acts via GABA(A) and GABA(B) receptors. Recently, a novel form of GABA(A) receptor-mediated inhibition, termed "tonic" inhibition, has been described. Whereas synaptic GABA(A) ... Read more...
Rapid assembly of functional presynaptic boutons triggered by adhesive contacts.
5 Oct 2009 CNS synapse assembly typically follows after stable contacts between "appropriate" axonal and dendritic membranes are made. We show that presynaptic boutons selectively form de novo following neuronal fiber adhesion to beads coated with ... Read more...
Stringent specificity in the construction of a GABAergic presynaptic inhibitory circuit.
30 Sep 2009 GABAergic interneurons are key elements in neural coding, but the mechanisms that assemble inhibitory circuits remain unclear. In the spinal cord, the transfer of sensory signals to motor neurons is filtered by GABAergic interneurons that act ... Read more...
