Narcolepsy is a disease that involves an alteration in the generation and organisation of sleep. The main symptoms are excessive daytime sleepiness and cataplexy, followed by hypnagogic hallucinations, sleep paralysis and disrupted nocturnal sleep. The prevalence of typical narcolepsy oscillates between 25-50: 100.

It guides the surgeon and minimises the risk of injury. This paper describes the different techniques available for IONM in spine surgery (somatosensory evoked potentials, motor evoked potentials, neurography, electromyography, reflexes and dermatomic evoked potentials), which neurophysiologists employ depending on the nerve structures at risk.

IONM uses different neurophysiological techniques during surgery time, thus avoiding possible lesions to the neurological structures, making surgery safer and better. We describe two types of IONM: mapping techniques and monitoring techniques, as well as their advantages, disadvantages and complications. We look into the more useful techniques in this field, as well as providing orientation about its use according to the surgical areas and the neurological structures under risk.

- Nonsystemic vasculitic neuropathy (NSVN) is an inflammatory condition affecting small blood vessels supplying nerves, often presenting as mononeuritis multiplex.
- A case of a 36-year-old woman with NSVN showed initial symptoms of tingling and weakness, with neurophysiological tests revealing low amplitude in the right median nerve and evidence of axonal damage.
- The study highlights that early ischemic nerve damage can cause misleading patterns in nerve conduction studies, indicating the need for repeated tests to accurately assess changes over time in suspected vasculitic neuropathies.
Objective: Predictable movements induce oscillatory changes over the contralateral motor cortex that begin before the movement, but their significance has not been fully established. We studied non-phase-locked changes in cortical oscillatory activity in a S1-centred double-stimulus go/no go paradigm with random interstimulus interval.
Methods: About 58 reference-free EEG channels were analyzed by means of Gabor transforms in a group of 10 healthy subjects.
