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.
Each cerebral hemisphere is divided into four lobes; the frontal, parietal, temporal, and the occipital. The Frontal Lobe is the most anterior lobe of the brain.Its posterior boundary is the fissure of Rolando, or central sulcus, which separates it from the parietal lobe.Inferiorly, it is divided from the temporal lobe by the fissure of Sylvius which is also called the lateral fissure.he Frontal Lobe is the most anterior lobe of the brain.
