AMPA receptor kinetics are uniform over the entire neuron. Amplitude versus time constant of desensitization for 32 patches from E16–E18 nMag neurons. There was no correlation between patch amplitude and desensitization at these ages, indicating that synaptic and nonsynaptic receptors were indistinguishable in kinetic characteristics. Correlation coefficient is 0.05. Inset, Representative traces from data points, marked by grayand black circles in main figure, which showed a 50-fold variation in amplitude (left), are identical in time course when peak responses are normalized (right).
