Functional magnetic resonance imaging (fMRI) based on blood oxygen leveldependent (BOLD) contrast is widely used for probing brain activity1. Neurovascular coupling constitutes the physiological basis for BOLD2, 3. Neurons, astrocytes and vessels cells are the main components of the neurovascular unit and work in concert to maintain the homeostasis of the brain microenvironment4, 5. The anatomical techniques demonstrated that astrocytes were connected the synaptic cleft with smooth muscle cells through multiple end feet. The morphology of astrocytes place them as likely a potential mediator, relaying synaptic activity between neurons and vasculature6. The goal of my doctoral project is to identify the astrocytic contribution to the BOLD fMRI signal by simultaneous BOLD fMRI and neuronal/astrocytic calcium signal recording.
