Information theoretic measures on target and inputs

Primary	px0	px1	Dx	I(T;X)
	0.1	0.3	3.36	1.36
	0.1	0.6	15.89	2.27
	0.1	0.9	50.72	2.32
Modulatory	py0	py1	Dy	I(T;Y)
	0	0.1	3.04	1.80
Target	Unimodal/multimodal proportion = 2/1
	Information content [entropy, H(T)] = 2.32

Relationships between spontaneous and driven activation probabilities for primary (p_x0, p_x1) or modulatory (p_y0, p_y1) inputs, Kullback-Leibler divergence measures for primary (D_x) or modulatory (D_y) inputs, and mutual information between target and primary [I(T;X)] or modulatory [I(T;Y)] inputs. The information content of the target [target entropy H(T)] is included for comparison.
