Angelman syndrome: current understanding and research prospects.

30 Oct 2009 Angelman syndrome is a neurogenetic disorder characterized by developmental delay, severe intellectual disability, absent speech, exuberant behavior with happy demeanor, motor impairment, and epilepsy, due to deficient UBE3A gene expression that may ... Read more...

Stability of electrical coupling despite massive developmental changes of intrinsic neuronal physiology.

3 Aug 2009 Gap junctions mediate metabolic and electrical interactions between some cells of the CNS. For many types of neurons, gap junction-mediated electrical coupling is most prevalent during early development, then decreases sharply with maturation. ... Read more...

Inhibitory regulation of electrically coupled neurons in the inferior olive is mediated by asynchronous release of GABA.

26 May 2009 Inhibitory projection neurons in the deep cerebellar nuclei (DCN) provide GABAergic input to neurons of the inferior olive (IO) that in turn produce climbing fiber synapses onto Purkinje cells. Anatomical evidence suggests that DCN to IO synapses ... Read more...
