Generate fMRI from neurotransmitter consumption As mentioned in this answer, it's possible to generate an fMRI BOLD signal from neurotransmitter consumption. What equation would be appropriate for this use?
The simplest equation for getting a BOLD signal from neurotransmitter that I could find was in "Tracing Problem Solving in Real Time: fMRI Analysis
of the Subject-paced Tower of Hanoi", which itself references many other publications where it was used:

$$H(t)= m \times(t/s)^a\times e^{-(t/s)}$$

The parameters $s$, $a$ and $m$ don't have an explicit meaning. Heuristically, from the text:


  $m$ is the magnitude of the response and $s$ is a time scale. The function
  peaks at time $a \times s$. The parameter a determines the shape of the
  function such that the larger $a$ is the more narrowly the function will
  be distributed around its peak.


So it seems you have to fit it to some previous data in the area you're trying to generate data from before it can be used.
