How do changes in the activity of cortical synaptic circuits lead to the onset of neuropsychiatric and neurodegenerative diseases? (albany.edu)

We reported that synaptic activity reduces the intraneuronal pool of Aβ (Tampellini et al. (lu.se)

Horizontal cell outputs inhibit (ie, reduce transmission at) nearby unilluminated receptor-bipolar cell synaptic junctions. (medscape.com)

Specific molecular complexes in the cell's outer shell, so-called 'receptors', receive the signal by binding the neurotransmitters. (technologynetworks.com)
A researcher at Vanderbilt University Medical Center, with colleagues from Japan and Oxford University in England, has solved the molecular structure of a mysterious glutamate receptor. (vumc.org)

Chen N, Ren J, Raymond LA, Murphy TH (2001) Changes in agonist concentration dependence that are a function of duration of exposure suggest N-methyl-D-aspartate receptor nonsaturation during synaptic stimulation. (yale.edu)

These data suggest that stimulation of glutamate D1 pyramidal neurons from the medial prefrontal cortex to the basolateral nucleus of the amygdala is both necessary and sufficient to produce the antidepressant effects seen with ketamine treatment. (bipolarnews.org)
