On page 229, Fig. 4a–c reproduced poorly because of a printer's error. The correct version is below.

Kinetics of activation of receptors containing wild-type α (a) , αV285I (b) or αV285A (c). Clusters of single-channel currents recorded at the indicated ACh concentrations from HEK cells expressing adult human nAChRs containing the indicated α subunits. Currents are shown at a bandwidth of 10 kHz, with channel openings as upward deflections.
