“…A similar approach based on sensory stimulation was recently proposed to assess consciousness in infants. 50 As they point out, peripherally evoked activity requires an intact thalamocortical system, which could not be the case for some unconscious patients.…”

“…In the bottom left quadrant, cortical dynamics are normal (so we risk overfitting), and we don't even know if our subjects possess consciousness. This includes human fetuses and newborns (Frohlich et al, 2023a ) and other animal species, especially those that are only distantly related to humans (Birch, 2022 ). Next, the bottom right quadrant includes subjects with abnormal cortical dynamics whose level of consciousness is uncertain, namely, DoC patients.…”

“…For many years, OPMs have been employed in MEG, starting from primary sensory systems with partial coverage and just 1-3 subjects [13]. Now, their practical scope spans medical applications, such as mapping of epileptic activity [14], fetal brain activity registration [15], measuring peripheral nervous system activity [16], contactless measurements of retinal activity [17] to purely neuroscientific endeavors. OPMs also open new possibilities to research of deep brain structures, such as hippocampus and cerebellum [18] and proceed in investigation of the motor system when the subject is in motion [19,20].…”

Nowadays, optically pumped magnetometers (OPMs) are gaining popularity in magnetoencephalography (MEG). However, like all sensors that work with biomagnetic signals, they are highly demanding to a low level of external magnetic field in the experimental environment. In the current paper, we proposed the experimental comparison of OPMs signal quality by recording their signal in two different magnetically-shielded rooms (MSRs) with different types of active suppression. Firstly, we conducted experiments in MSR in absence of additional local active shielding (only with one embedded into the walls). Next, we built the adaptive system of active suppression (ASAS), lightweight and portable, in another MSR and tested OPMs there. For this purpose we used sensors of two generations (Gen-1 and Gen-3) of commercial OPMs manufactured by QuSpin Inc. and tested them with standard signals generated by phantom and test coil. The results showed that MSR with installed ASAS in it enable OPMs to work optimally and give reliable results, while OPMs tested in the MSR containing SQUID system and active shielding embedded into the MSR walls, show unstable signal with low reproducibility. This study will undoubtedly facilitate research groups in building their own OP-MEG systems and understand the nature of false sensor deterioration.
