AMPA receptors are thought to be a tetrameric assembly of the subunits GluR1-4. We have examined whether two coexpressed subunits (GluR1/2) combine at random to form channels, or preferentially assemble with a specific stoichiometry and spatial configuration. The subunits carried markers controlling ion permeation and desensitization, and these properties(More)
Fragile X is a synapsopathy--a disorder of synaptic function and plasticity. Recent studies using mouse models of the disease suggest that the critical defect is altered regulation of synaptic protein synthesis. Various strategies to restore balanced synaptic protein synthesis have been remarkably successful in correcting widely varied mutant phenotypes in(More)
Kainate receptors (KARs) are heteromeric ionotropic glutamate receptors (GluRs) that play various roles in the regulation of synaptic transmission. The KAR subunits GluR5 and GluR6 exist under different splice variant isoforms in the C-terminal domain (GluR5a, GluR5b, GluR5c, GluR6a, GluR6b). The differential role of KAR subunit splice variants is presently(More)
microliter, a value not so different from the volume density of transistors. Each synapse requires around 3 to 4 μm of wire (axon and dendrite) to support it, and each transistor on a microprocessor chip is supported by about 30 μm of wire. Again, the numbers are not so different and the wire diameters are also close to the same (on the order of 100 nm).(More)
