Rheoencephalography (REG) a technique[1] of continuous registration of cerebral blood flow. An electronic device called a rheoencephalograph is used in rheoencephalography.[2] Electrodes are attached to the cranium at specific points on the head and allow the device to continuously measure the electrical conductivity of the tissue located between the electrodes. A rheoencephalograph is also used for brain blood flow biofeedback.[3]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
