1 and can activate Ca action potentials
2 Na action potentials support backpropagating impulses
3 The physiology of these receptors has been studied in outside-out patches from the proximal apical dendrites. It was found that a CNQX-sensitive component of the synaptic current evoked by fast aplication of glutamate could be isolated (and was presumed to be the result of AMPA channel opening). It was calculated that AMPA channels had a mean elementary conductance of 10 pS (estimated by non-stationary fluctuation analysis) and was found that the channels had a low permeability to Ca2+. The reversal potential for AMPA receptors was found to be about 0 mV with an almost linear peak current-voltage relationship
4 The physiology of these receptors has been studied in outside-out patches from the proximal apical dendrites. It was found that an APV-sensitive component of the synaptic current evoked by fast aplication of glutamate could be isolated (and was presumed to be the result of NMDA channel opening). It was calculated that NMDA channels had a main conductance state conductance of 45 pS and it was confirmed that the channel was permeable to Ca2+. The NMDAR-mediated conductance was blocked by Mg2+ in a voltage-dependent way and by Zn2+ in a non-voltage-dependent fashion
5 which is important for the induction of long term changes in synaptic strength"
