The PATHWAY system offers advanced models, including the CHEPS (Contact Heat-Evoked Potential Stimulator) and ATS (Advanced Thermal Stimulator). Utilizing contact thermal probes, this system evaluates cold and warm detection thresholds, as well as cold pain and heat pain detection thresholds. It also determines tolerance thresholds and applies supra-threshold painful stimuli at predetermined temperatures. The CHEPS model provides a rapid rise time of up to 70°C/s. Available probes include standard and MRI-compatible CHEPS probes (27 mm diameter), standard and MRI-compatible ATS probes (30 mm x 30 mm), and an additional standard ATS probe (16 mm x 16 mm).
