Applications:

• The CHEPS thermode’s ability in heat and cold pulses enables recording of both contact heat evoked potentials (CHEPs) and cold evoked potentials (CEP) via EEG. CHEPS allows delivery of sharp and rapid thermal stimulation, essential for the recording of evoked potentials.
  The TSA 2 device can be fully synchronized with the EEG application via TTL IN and OUT, allowing intuitive EEG data analysis.

• CHEPS for TSA 2 allows the delivery of repeated fast painful stimuli, at the frequency required for Phasic Temporal Summation, a phenomenon in which repeated and equal-intensity noxious stimuli cause an increase in the pain experienced. Temporal summation in an important protocol in pain research and can be used to assess central sensitization and better understand the mechanisms of chronic pain in various etiologies.

• CHEPS for TSA 2 is available in fMRI configuration, with accelerated rates, to apply precise and immediate thermal stimulation in the fMRI environment. The CHEPS thermode can be also used in combination with other neuroimaging techniques. External Control capabilities allow the precise and timed implementation of the fast heat and cold stimulation in complex and sophisticated experiments, to be combined with other types of stimulation, psychological or physical tasks, and more.
