Using cutting - edge 3D microscopy, researchers from the National Heart, Lung, and Blood Institute and Yale University examined the subcellular architecture of presynaptic terminals in retinal bipolar cells of live goldfish. (sciencedaily.com)
The mechanism of presynaptic facilitation, therefore, may include activation of one or more serotonergic neurons, which enhance the release of a neurotransmitter by increasing the intracellular concentration of cyclic AMP in the terminals of the sensory neurons. (science.sciencemag.org)
We isolated NMDA - R EPSC responses for cortical layer 4 → layer 2/3 (L4 → L2 / 3) projections by recording neurons in L2 / 3 while electrically stimulating presynaptic neurons in L4 during constitutive pharmacological block of other ionotropic glutamate receptors (AMPA and kainate receptors) and GABA receptors.
