Fig 8. Changing the temperature of the system.
The linear relationship νinh(νexc) in (a) can keep the offset of the response function constant (solid line in (b)), while only changing the slope of activation functions and thereby the temperature of a network (dashed line line in (b)). This relationship also reflects the relative strengths of afferent excitatory and inhibitory weights. (c) Three example activation functions with constant offset for different background rates. Colors correspond to those in panel a. Here, we emphasize the binary-state interpretation by plotting p(z = 1|Iin) = νoutτref (cf. Fig 1c).
