![]() Parietal Lobe: processes sensory information (temperature, touch, taste) while allowing for visuospatial processing (tracking objects and avoiding collisions) Frontal Lobe: controls executive functions, cognitive abilities such as problem-solving, planning and decision-making, as well as personality As a result, each hemisphere contains four lobes: frontal, parietal, occipital and temporal. The brain is almost symmetrical, with only slight morphological inconsistency. Conversely, the right hemisphere takes charge of creativity, imagination, intuition and spatial awareness.Īs the two sides constantly communicate through the corpus callosum, a collection of nerve fibers between linking the two halves, you’re able to engage both hemispheres simultaneously, necessary for countless cognitive feats and voluntary movements. The left hemisphere is credited for logic, analytical, reasoning, language and numerical skills. This explains why victims of right-hemisphere strokes experience paralysis or sensory impairment on the left side of the body. The left hemisphere controls the right side of the body, whilst the right hemisphere controls the left side of the body. The cerebrum is split into two halves (hemispheres), colloquially referred to as the left and right sides of the brain. Delving deeper into the cerebrum, we find that this organ can be further separated into more minor constituents. While acting as this communication hub, the brain stem also controls automatic functions like breathing, temperature, digestion, swallowing, and sleep cycles. The brainstem connects the cerebrum and cerebellum to the spinal cord, thus relaying their messages and instructions throughout the body. Without this “little brain,” you would be unable to enact virtually all physical movement. However, it’s integral for motor control as well as maintaining balance and posture. Tucked neatly away, the cerebellum accounts for only 10% of brain mass. The cerebrum controls higher functions like reasoning, speech, and emotion, as well as touch, sight and hearing, and many other responsibilities. The wrinkled appearance is the evolutionary consequence of forming hills (gyri) and valleys (sulci) to maximize computational power given limited volume.Īs this part is approximately 85% of total brain weight, it’s no surprise it has a long list of jobs to do. When most people picture the brain, they’re looking at the cerebrum. ![]() There are three main areas of the brain: the cerebrum, the cerebellum, and the brain stem. While we’re nowhere close to a comprehensive understanding of this three-pound organ, we can localize certain functions and aspects to specific regions, including memory. There are 86 million neurons in the brain, forming a dense network of pathways. After all, this is the organ that built the pyramids, painted the Sistine Chapel, wrote Shakespearean sonnets, and landed on the moon. The brain is far more intricate than a few bits and pieces stitched together. Working in unison the brain allows for a person to control their memories. These parts of the human brain serve in the creation of memories, storing memories, and the retrieval of memories. Consisting of three main areas: cerebrum, cerebellum, and the brain stem.
