Unformatted text preview: Quiz 1: Wednesday, April 9, 2008 Figure 1 shows the structure of a dendritic tree with an excitatory synaptic input applied at the
end of one branch. The synaptic conductance is g2 and the reversal potential is Ee. C1, C2, and C3
refer to cables 1, 2, and 3 with electronic lengths L1, L2, and L3. (31, 62, and 63 are input
conductances looking into each cable from the indicated directions. 613 is the output
conductance (also called the terminating conductance) of cable C2. Voltages V0, V1, and V2 are
as shown in Figure 1. Assume that the input conductance of an semiinfinite extension of each
cable, Gun, is identical for each cable. Our goal is to compute V0, the voltage response at the
"soma" in response to the excitatory dend ritic input. A. Solve for V2 in terms of g2, 62, and E8.
B. Solve for V1.
C. Solve for V0. ...
