The passage around this formula
The empirical question of what n should be was addressed directly by Logothetis, Pauls, Augath, Trinath and Oeltermann, who recorded neural signals and BOLD simultaneously in monkey visual cortex. They found that local field potentials gave a better estimate of the BOLD response than multi-unit spiking did, and that at recording…
