Using ultrafast and ultrahigh field magnetic resonance imaging (fMRI), researchers at the Champalimaud Foundation and the University of Minho have found evidence of resonant waves in rat brain activity. This means that the brain seems to be a resonant chamber where distant brain areas show correlated activations due to collective wave modes [1].

Many theoretical works have proposed models based on standing waves to explain the macroscopic patterns observed [2-5], though the nature of such activations remains unclear. To delve deeper into this mechanism and understand how distant areas exhibit signal correlations, and how they are implicated in brain function, experimental evidence required a better temporal resolution of the fMRI spectras to show the spatial pattern oscillations and prove the hypothesis that these macroscopic patterns result from the distinct or independent transient oscillation modes at...
