Bilinearity in Spatiotemporal Integration of Synaptic Inputs
Figure 5
Shunting coefficient in branched dendrites measured in experiments.
The data marked by grey squares were collected from 7 neurons in our experiments, and lines connect data from the same neuron. The data marked by black squares are the average of the data marked by grey squares. The error bar indicates one standard deviation. In all figure panels, the locations of the inhibitory input (I) and excitatory inputs (E1 and E2) are marked by a blue dot and red dots, respectively. The I path is marked by green. (A) The inhibitory input I at an oblique branch: is nearly constant for two distal E1 and E2 on the same branch. (B) As in (A) except that E1 and E2 are more proximal than I.
is significantly different at E1 and E2 sites. (C) The inhibitory input I at the trunk:
is nearly constant between E1 at the trunk and E2 at the oblique branch. (D) The inhibitory input I at an oblique branch:
is significantly different between E1 and E2, where E1 is on the same branch as I and E2 is on a different branch.
