Galvaanijärjestelmä

Galvaanijärjestelmä refers to a group of organs and tissues in the human body responsible for the process of electroreception, though it is far less developed and functional compared to electroreceptive organs found in some fish and amphibians. In humans, this system is not a distinct, anatomically defined organ system like the nervous system or circulatory system. Instead, it is thought to be a vestigial or rudimentary capacity, potentially linked to sensory pathways or cellular electrical activity that has not evolved into a primary sensory modality.

The concept of a human galvaanijärjestelmä is largely theoretical and debated. Some researchers suggest that certain electrical fields generated by the body's own cells might be perceived at a very subtle level, though this perception is not consciously recognized or integrated into our sensory experience in the way vision or hearing are. Unlike animals that use electroreception for navigation, hunting, or communication, humans do not appear to possess specialized electroreceptors capable of detecting external electric fields with any significant acuity.

While the term "galvaanijärjestelmä" is used, it is important to note that it does not represent a fully developed biological system in humans. Research in this area is ongoing and focuses on understanding the fundamental electrical properties of biological tissues and whether any residual or latent electroreceptive capabilities exist. The prevailing scientific view is that humans are not electroreceptive in a functional sense.
