👉 Seisactinomyxon is a term used in biological medicine, specifically referring to a type of tumor that occurs due to an abnormality in the structure or function of nerve cells in the brain. This condition can be caused by mutations within the genetic material of these neurons, leading to abnormal signals from the brain's sensory and motor cortex. Seisactinomyxon is characterized by changes in the structure of the brain, including abnormal patterns of activity and connectivity between different areas of the brain.
