John, let's sort out electrical units for you, The unit of EMF or PD is the Volt after an Italian who 'invented' the first battery The unit of current is the Ampere after a Frenchy who was first to measure current flow The unit of resistance is the Ohm, after an Austrian G.S. Ohm who first recognised this property in a conductor.
1 Calcarin's fissure: extends from the occipital of the cerebrum to the occipital fissure. 2  Callosomarginal fissure: found in the mesial surface of the cerebrum. 3  Central sulcus or Rolando's fissure: separates the brain's frontal and parietal lobes. Medial longitudinal fissure or Longitudinal fissure: which divides the cerebrum into the two hemispheres. 2  Fissure of Bichat: found below the corpus callosum in the cerebellum of the brain. 3  Broca's fissure: found in the third left frontal fold of the brain.
Structure [edit]. Sulci are one of three parts of the cerebral cortex, the others being the gyri and the fissures. The three different parts create a larger surface area for the human brain and other mammalian brains. When looking at the human brain, two-thirds of the surface is hidden in the grooves.The sulci and fissures are both grooves in the cortex but they are differentiated by size. A sulcus is a shallower groove that surrounds a gyrus.ulci are one of three parts of the cerebral cortex, the others being the gyri and the fissures. The three different parts create a larger surface area for the human brain and other mammalian brains.
