The role of receptor subtype diversity in the CNS.
The molecular characterization of neuroreceptors and voltage-gated ion channels has revealed that receptor subtype heterogeneity is a common feature of chemical and electrical signal reception. The use of distinct genes encoding receptor subtypes is a favoured mechanism for generation of this diversity. We propose that the significance of the multiplicity and diversity of signal reception proteins is to increase the information-handling capacity of neurons. This may contribute to neural plasticity.
