Abstract:
Progressive nuclear palsy (PSP) is a parkinson-like extrapyramidal disorder with pathological evidence of brain stem demyelination. We studied brain stem auditory (BAEP) and somatosensory (SSEP) evoked potentials in 8 patients with progressive supra-nuclear palsy to look for evidence of such central demyelination. We found minor alterations in BAEPs and frequently abnormal SSEPs, suggestive of brain stem white matter involvement in this disorder. Evoked potentials may assist in the differentiation of PSP from other parkinsonian conditions.

Propagation of Action Potentials
Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions. When a stimulus, like a touch or a signal from another neuron, triggers the neuron, sodium channels open, allowing sodium ions to...
