[...] Increased oxygen consumption might reflect neural inputs (e.g. synaptic activity at dendrites) or it might reflect neural outputs (e.g. action potentials at axons). Viswanathan et al. used a creative experimental design to distinguish between these possibilities. They used dual microelectrodes to simultaneously measure local oxygen levels, spiking activity and local EEG signal (or field potentials) in the cat visual cortex. They found that oxygen levels correlated most closely with the local EEG signal, which is known to reflect dendritic inputs rather than axonal outputs. For a review of this connection please check out my Method of the Month feature. [...]
