Title and Abstract:
Neurovascular coupling revisited: secondary synaptic activity and not thalamic inputs drives hemodynamic response

In a series of experiments in humans and small animals we investigated the relationship between the electrical and vascular signals measured during neuronal activity. We used macroscopic electrical (MEG in humans, EEG in rats) and vascular measurements (diffuse optical imaging (DOI)).
In different experiments we modulated neuronal activity with parametric electrical stimuli (humans and rats) as well as with cortical infusion of GABA and use of different anesthetics (rats). The results indicate that the secondary postsynaptic activity in superficial cortical layers—not the initial activity in layer IV— drives the hemodynamic response.
