The relationship between the blood-oxygenation-level dependent (BOLD) signal and its underlying neuronal activity is still inconclusive. The task of completely understanding this relationship has been encumbered not only by the complexity of neuronal responses, but also by nonlinear characteristics of the vascular response that are not correlated to neural activity. Repeated stimuli inducing replicable neural responses led to successively smaller BOLD amplitudes and delayed BOLD onset latencies… CONTINUE READING
