Using the patch clamp technique, a researcher measures a single channel in a membrane. the receptor channel passes 3 pa (picoamperes) of ionic current over a period of 8 msec at -60 mv; 1 pa = 10 -12 ampere. based on your knowledge of nerve transmission, this movement of ions willa. stimulate a change in a postsynaptic membrane if 50 channel events are combined. b. stimulate a change in a postsynaptic membrane if three channel events are combined. c. not stimulate a change in a postsynaptic membrane. d. generate a current resulting in membrane depolarization. e. stimulate a change in a postsynaptic membrane
