NMDA receptor. NMDA receptors (NMDAR), glutamate receptors are the predominant molecular device for synaptic plasticity and to control the memory function.
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of a large number of closely spaced turns of wire that create the magnetic field.
Summary Magnetsâ¢ â¢ All magnets have a north pole and a south pole.Like magnetic poles repel each other and â¢ unlike magnetic poles attract each other. A magnet is surrounded by a magnetic fieldthat exerts a force on other magnets.ummary Magnetsâ¢ â¢ All magnets have a north pole and a south pole.Like magnetic poles repel each other and â¢ unlike magnetic poles attract each other.
