all-in-one solution that sets new standards in neuroscience lab equipment
Straight to:
LOOP-IT enables state-dependent and closed-loop controlled experiments without prediction, Temporal Interference Stimulation and neuromuscular stimulation – all simultaneously and synchronously and within one box.
The simultaneous application of non-invasive brain stimulation (NIBS) and EEG has significantly advanced our comprehension of NIBS-induced local and network effects, as well as the functional role of brain oscillations. The manipulation of individual parameters, such as intensity, frequency, and phase, can influence the outcomes of NIBS. State-dependent NIBS allows researchers to precisely control these parameters and influence brain activity with high temporal and spectral precision.
The system ensures minimized constant delays between data acquisition, analysis, event detection, and derived parameters for the output module (e.g., tES current source, trigger of TMS).
Functioning as a multi-channel stimulator for 2 or 4 transcranial and / or peripheral stimulations, our current sources exhibit low noise, high temporal precision, and galvanic isolation. This setup is specifically designed for temporal interference stimulation as well as pairing transcranial and neuromuscular stimulation, providing a comprehensive solution for advanced neuroscience research.

The device can be operated from the mains or via the battery pack.
