One of the ubiquitous features of neurons is that there is a complex and diverse structure of dendrites converging to the neural soma [].The connections between neurons are distributed over dendrites and manifested by different types of synaptic receptors [].The NMDA (N-methyl-D-aspartate) receptor (NMDAR) is a … WebThese receptors are permeable to calcium ions, and activation results in a calcium influx into post-synaptic cells, which results in the activation of several signaling cascades. Disruption of this gene is associated with focal epilepsy and speech disorder with or without cognitive disability.
