Figure 8. Spine Ca2+ transients are controlled by mGluR1 or M1 muscarinic receptor inhibition of SK channels.

Figure 8

mGluR1 or M1 muscarinic receptors inhibit SK channels, which removes a negative feedback regulation of NMDARs within dendritic spines thereby enhancing Ca2+ influx. Facilitated Ca2+ influx through NMDARs and Ca2+ influx through VSCCs are both required for the induction of LTP by STDP.
