Information. The cerebrum is divided into 2 hemispheres (right and left) by a deep groove known as the longitudinal fissure. What separates the cerebellum into two hemispheres? The lateral fissure extends in three directions, rostrally as the anterior ramus, superiorly as the ascending ramus, and caudally as the posterior ramus. This groove separates the temporal lobe from the parietal lobe. The longitudinal fissure separates the two cerebral hemispheres and the transverse fissure is what separates the cerebrum from the . It is the largest white matter-based (myelinated axon) structure in the brain. However, the most characteristic feature of the reptilian forebrain is the so-called dorsal ventricular ridge (DVR), a mass of neural tissue that protrudes into the lateral ventricle (Figure 1).The cerebral hemispheres in birds are organized in a pattern similar to that in reptiles . The cerebrum controls somatosensory, motor, language, cognitive thought, memory, emotions, hearing, and vision. BI 335 . The transverse cerebral fissure separates the cerebral hemispheres from the cerebellum and contains the horizontal slip of dura called tentorium cerebelli. the two regions of the cerebral hemispheres, one in each hemisphere, that are anterior to the central fissures parietal lobe the two regions of the cerebral hemispheres, one in each hemisphere, that are posterior to the central fissures and superior to the lateral fissures temporal lobes B) The cerebral hemispheres account for about 83% of total brain mass.
