Card 19 / 30: Which of the following is true about transmission of EPSPs along dendrites.
A)
EPSPs become smaller in amplitude and shorter in duration as they move along passive dendrites
B)
Potentials travel more readily away from the soma than towards it
C)
Inhibitory inputs shunt EPSPs more readily when then are near the cell body than when they are in distal dendrites
D)
At dendritic branch points the length constant can either increase, decreaor stay the same
E)
EPSPs from distal dendrites are often larger than expected from passive propagation both because synapses are stronger at distal locations and because they can stimulate action potentials in the dendrites
