The lake is about 205 ft. deep and boosts of having more than 51 recreational spots. Not only this, it is a home to several species of fish including Salmon fish, catfish, northern pike and many others. With that, Lake Oahe ranks at number 10 on our list of top 10 largest man made lakes in the world.
The postsynaptic density (PSD) is a protein dense specialization attached to the postsynaptic membrane. PSDs were originally identified by electron microscopy as an electron-dense region at the membrane of a postsynaptic neuron.
We now know that these dense postsynaptic thickenings represent a fibrous specialization of the submembrane cytoskeleton that adheres to the postsynaptic membrane at sites of close apposition to the presynaptic terminal.ntil recently, many of the major proteins in the highly insoluble postsynaptic density fraction remained uncharacterized. Modern immunological and microsequencing methods now make it possible to define more precisely the molecular composition and function of this intriguing organelle.
