Apr 30, 2015  · Synaptic neurotransmission is known to be an energy demanding process. At the presynapse, ATP is required for loading neurotransmitters into synaptic vesicles, for priming synaptic vesicles before release, and as a substrate for various kinases and ATPases. Although it is assumed that presynaptic sites usually harbor local mitochondria, which may serve as energy powerhouse to.

Apr 02, 2012  · Background Dendritic spines are small membranous protrusions on the neuronal dendrites that receive synaptic input from axon terminals. Despite their importance for integrating the enormous information flow in the brain, the molecular mechanisms regulating spine morphogenesis are not well understood. NESH/Abi-3 is a member of the Abl interactor (Abi) protein family, and its overexpression.

the combination of this assay with total internal reflection fluorescence microscopy may represent a promising tool for high-resolution study of the mechanisms of vesicular release at the presynapse.

The calyx of Held is a type of giant glutamatergic presynaptic terminal in the mammalian auditory brainstem that transmits afferent information from the cochlear nucleus to the medial nucleus of the trapezoid body (MNTB). It participates in sound localization, a process that requires very high temporal precision. Consistent with its functional role, the calyx shows a number of specializations.

Our results show that the structure and electrical properties of basal dendrites can partially normalize the somatic contribution of EPSPs generated at different dendritic locations, which is.

This can be accounted for by changes in the synaptic structure and surrounding neuropil, rather than by a change in AMPAR properties. Our findings raise the possibility that structural alterations.

Aug 29, 2012  · How size and shape of presynaptic active zones are regulated at the molecular level has remained elusive. Here we provide insight from studying rod photoreceptor ribbon-type active zones after disruption of CAST/ERC2, one of the cytomatrix of the active zone (CAZ) proteins. Rod photoreceptors were present in normal numbers, and the a-wave of the electroretinogram (ERG)—reflecting their.
