Total duration of stimulus vector in seconds. |

Based on the provided stimulus boxcar function, a neural activation function is generated that enters the Balloon model to generate a BOLD response. The microtime resolution ensures a high-precision generation of the response. More details can be found in Buxton et al. (2004).
Vector representing the values of the BOLD signal for the given stimulus vector and microtime resolution.
