Differential Presynaptic Localization of Metabotropic Glutamate Receptor Subtypes in the Rat Hippocampus
Subtype-specific antibodies were used for immunohistochemistry combined with lesioning of the three major hippocampal pathways to establish the precise localization of presynaptic mGluRs in the rat hippocampus, suggesting that transmitter release is differentially regulated by 2-amino-4-phosphonobutyrate-sensitive mGLURs in individual synapses on single axons according to the identity of postsynaptic neurons.
GABAB-receptor subtypes assemble into functional heteromeric complexes
A new GABAB receptor subtype is described, GABABR2, which does not bind available GABAB antagonists with measurable potency and exhibits a significant increase in agonist- and partial-agonist-binding potencies as compared with individual receptors.
Molecular cloning and characterization of the rat NMDA receptor
A complementary DNA encoding the rat NMDA receptor has been cloned and characterized and it has been found that this protein has a significant sequence similarity to the AMPA/kainate receptors.

Immunohistochemical localization of Ih channel subunits, HCN1–4, in the rat brain
The results indicate that HCNs are localized not only in somato‐dendritic compartments but also in axonal compartments of neurons and further suggest unexpected roles of Ih channels in the brain.

The results suggest that HES-1 may play an important role in mammalian development by negatively acting on the two different sequences while Hes-3 acts as a repressor in a specific type of neurons.

It is proposed that glutamatergic synapses with an irregular edge develop in order to increase the circumference of synaptic junctions leading to an increase in the metabotropic to ionotropic glutamate receptor ratio at glutamate release sites.

The results reveal the complex cell surface distribution of voltage-gated ion-channels, and predict its role in increasing the computational power of single neurons via subcellular domain and input-specific mechanisms.
