Unformatted text preview: Once NMDA is active Ca2+ enters the cell (in addition to Na+ and K+). This can lead to certain forms of associative LTP. NMDA receptors may also be involved with LTD. 7-8. What’s a major difference between ionotropic receptors and metabotropic receptors? Ionotropic receptors double as an ion channel; metabotropic receptors require an intracellular signal cascade. 9-10. List two characteristics of electrical synapses. (Ex. How is their structure/function different from chemical synapses?) Gap junctions Little delay of signal...
