Biomagnetism is the phenomenon of magnetic fields produced by living organisms; it is a subset of bioelectromagnetism.In contrast, organisms' use of magnetism in navigation is magnetoception and the study of the magnetic fields' effects on organisms is magnetobiology.
Magnetoencephalography (MEG) is a functional neuroimaging technique for mapping brain activity by recording magnetic fields produced by electrical currents occurring ...
Birds have iron-containing materials in their upper beaks. There is some evidence that this provides a magnetic sense, mediated by the trigeminal nerve , but the mechanism is unknown. Cartilaginous fish including sharks and stingrays can detect small variations in electric potential with their electroreceptive organs, the ampullae of Lorenzini .

Electromagnetic Source Imaging is a functional imaging technique, which uses Electroencephalography (EEG) and/or Magnetoencephalography measurements to map functional areas of the Cerebral cortex. [1]

TMS can be used clinically to measure activity and function of specific brain circuits in humans, most commonly with single or paired magnetic pulses. [8] The most widely accepted use is in measuring the connection between the primary motor cortex of the central nervous system and the peripheral nervous system to evaluate damage related to past or progressive neurologic insult.
Cortical stimulation mapping is an invasive procedure that has to be completed during a craniotomy.Once the dura mater is peeled back, an electrode is placed on the brain to test motor, sensory, language, or visual function at a specific brain site.
