A. The Transcranial <t>Electrical</t> Stimulation with Temporal Interference (TES T!) system comprised the Temporal Interference Brain Stimulator for Research (TIBS-R) with components including the Intelligent Current Source (JCS), electrode connector box (ECB), and high-pass filter (HPF). Current was delivered through two pairs of stimulating electrodes (four electrodes total) embedded in the hd-EEG net. All other hd-EEG recording channels (252) passed through a low-pass filter (LPF) before reaching the recording amplifier. The dual HPF and LPF system allowed for simultaneous TES-TI and hd-EEG recording. Trigger (TRIG) outputs from the TIBS-R allowed for identification of when stimulation occurred. B . TES 15kHz -TI 1Hz consisted of one pair of electrodes delivering high frequency alternating current (E 1 : 15,000 Hz) and the other pair delivering high frequency alternating current with an offset (E 2 : 15,0001 Hz) to create amplitude modulation at the difference frequency (1 Hz) deep in the brain. C . Simulated temporal interference electric field in grey matter for an individual participant. Maximum electric field values occurred in deep, left ventromedial prefrontal cortical regions with values exceeding 0.7 V/m. D . (Top) A single stimulation protocol with three-minute periods before (PRE), during (STIM), and after (POST) stimulation. Three channels of example EEG data during ten seconds within each three-minute period shown. (Bottom) Representative example of the set of stimulations during NREM sleep, with ten stimulations occurring within the first hours after sleep onset.

Article Snippet: Fetal, infant, and toddler (FIT) neuroimaging researchers study early brain development to gain insights into neurodevelopmental processes and identify early markers of neurobiological vulnerabilities to target for intervention.. However, the field has historically excluded people from global majority countries and from marginalized communities in FIT neuroimaging research.. Inclusive and representative samples are essential for generalizing findings across neuroimaging modalities, such as magnetic resonance imaging, magnetoencephalography, electroencephalography, functional near-infrared spectroscopy, and cranial ultrasonography.
