Simple Summary: This study used the superlet transform and the cluster depth test to compute the time–frequency representation (TFR) of the oscillatory differences between neural activities recorded by magnetoencephalography with optically pumped magnetometers while participants were listening to congruent and incongruent Chinese semantics. Then, the differences were parameterized based on the definition of local events. The results showed the TFRs of the differences in oscillatory activity occurring during various semantic processing tasks. The specific times, frequencies, and brain regions in which these differences occurred were demonstrated in detail. These results revealed the specific manifestations of the differences in neural oscillation activities during the cognition of semantically congruent and incongruent stimuli, which also revealed the potential causes of the differences in N400m neural activity and mismatch activities from the perspective of neural oscillations. Neural oscillations observed during semantic processing embody the function of brain language processing. Precise parameterization of the differences in these oscillations across various semantics from a time–frequency perspective is pivotal for elucidating the mechanisms of brain language processing. The superlet transform and cluster depth test were used to compute the time–frequency representation of oscillatory difference (ODTFR) between neural activities recorded by optically pumped magnetometer-based magnetoencephalography (OPM-MEG) during processing congruent and incongruent Chinese semantics. Subsequently, ODTFR was parameterized based on the definition of local events. Finally, this study calculated the specific time–frequency values at which oscillation differences occurred in multiple auditory-language-processing regions. It was found that these oscillatory differences appeared in most regions and were mainly concentrated in the beta band. The average peak frequency of these oscillatory differences was 15.7 Hz, and the average peak time was 457 ms. These findings offer a fresh perspective on the neural mechanisms underlying the processing of distinct Chinese semantics and provide references and insights for analyzing language-related brain activities recorded by OPM-MEG.
