The CCT (Cervical Central Time) for median nerve somatosensory evoked potentials (SSEPs) refers specifically to the time intervals between two critical peaks that are observed in the waveform generated during the testing. In the case of median nerve SSEPs, the CCT is measured from the positive peak labeled P14 to the negative peak labeled N20.

These peaks are important because they reflect the electrical activity in the central nervous system that occurs after stimulation of the median nerve at the wrist. The P14 wave usually represents activity in the cervical spinal cord or brainstem, and the N20 wave corresponds to activity in the somatosensory cortex. Thus, the timing between these specific peaks provides information about the conduction of sensory signals through the central nervous system and can be used to assess function during surgical procedures.

Understanding these specific time points is crucial for monitoring and ensuring the integrity of neural pathways during surgeries that may present risk to nerve function.
