The cerebrum or the cortex is the largest part of the human brain. The cerebrum is divided into four sections which are the front lobe, parietal lobe, occipital lobe, and the temporal lobe. The frontal lobe is associated with reasoning, planning, movement, emotions, and problem solving. The frontal lobe also recognizes sarcasm and irony. It is located at the front part of the brain. The partial lobe is located at the back of the frontal lobe and on top of the temporal lobe. It associated with orientation and recognition of a perception of stimuli. The occipital lobe is located at the very back part of the brain. Its main functions are visual processing and visual integration. Lastly the temporal lobe is located at the sides just below the temple. Because of its unique location near the ears, it is where the auditory cortex is located. It plays a role in hearing, organization, and memory.
The cerebellum is a region of the brain that plays an important role in motor control. It is located at the posterior base of the brain. Like the cerebrum, the cerebellum is covered by cortex and consists of two hemispheres, each of which is divided into lobes. The hemispheres are separated from one another by a thin structure called the vermis, or "worm." The anterior lobe is the second oldest part of the cerebellum. It receives proprioceptive input from the spinal cord and controls the anti-gravity muscles of the body. The posterior lobe is the newest part of the cerebellum. It is involved in the coordination of muscle movement via the inhibition of involuntary movement.The flocculonodular lobe consists of the flocculi, the most ancient part of the cerebellum, and the nodulus, the narrowest and most inferior part of the vermis. This lobe is involved in the maintenance of equilibrium.
The brainstem is located at the juncture of the and the spinal column. It is anterior to the . The brainstem is the region of the that connects the with the spinal cord. Motor and sensory travel through the brainstem allowing for the relay of signals between the brain and the spinal cord. The brainstem controls several important functions of the body which are alertness, arousal, breathing, blood Pressure, digestion, and heart rate. Components of the brain stem include the medulla and the pons. The medulla contains the brain regions that control breathing, the heart, swallowing, , and defecation. Just above it is the pons, which is the characteristic bulge of the brain stem. Its main roles are to relay sensory information between the and the , also helps regulate , and controls arousal.
` How does information in flow through the brain? Information flows from the outside world through our sight, hearing smelling, tasting, and touch sensors. Memory is simply ways we store and recall things we've sensed. There are three stages in the retrieval of the memory. In the first stage we must change the information so that we may put the memory into the encoding process. The second memory stage or process if storage. This entails that we maintain information over periods of time. Finally the third process is the retrieval of information that we have stored. We must locate it and return it to our consciousness. We also have two types of memory which are short term and long term memory. In short term memory it allows recall for a period of several seconds to a minute without rehearsal and its capacity is also very limited. Long-term memory can store much larger quantities of information for potentially unlimited duration
It is always best to keep your brain healthy because everything we do, see, feel, smell and touch all originate in the brain. Without the brain the body couldn't function. For example your stomach wouldn't know when it was full or hungry if we didn’t have a brain. In order to maintain a healthy brain it is good to use them every day, challenge them with puzzles and brain teasers so we can have use of our brains as long as possible. Any damage to the brain does not only erase memories but also may deceive the brain. Without a brain you would be like a corpse.
