Fig. 7. Signaling dynamics of dopamine systems subjected to noise. Noise frequencies are 100 Hz, 40 Hz and 10 Hz in rows
1, 2, and 3, respectively. Left column:
w
1
=
0.01s;
w
2
=
0.01s; right column:
w
1
=
0.01s;
w
2
=
0.2s. The lowest sub-panel
for each example shows a train of 10 signals; the center sub-panel visualizes the discrete Gaussian noise applied to the system,
while the upper sub-panel shows the system response (DA-e level) to the signal train. Smoother lines in upper sub-panels show
results for the unperturbed system, while more ragged lines show results for systems exposed to noise. Unit for
x
-axes: seconds
(s); units for
y
-axes, from bottom to top: signal strength; percentage of noise to baseline; DA-e ratio to baseline.
