Gamma-frequency band activity coupling with pO2 responses. Each data point represents an hourly averaged response from animals injected with either vehicle (black) or IL-1β (red), normalised to the animal’s pre-injection response. Coupling between gamma neural activity and the corresponding pO2 response is maintained in vehicle-treated animals (black line is line of best fit), whereas there is no correlative relationship seen between these parameters in IL-1β-treated rats. n = 4 animals for each group; six responses per animal (one per hour post-injection)
