The Different Lobes of the Brain and its Structure

A peer-reviewed scientific publication called Brain Disorders & Therapy is renowned for its quick distribution of top-notch research. Authors in academia and business can publish their original research on an open access basis in this high impact factor journal for brain disorders. It provides the International Scientific Community with its typical papers on brain research.

Brain:- The brain interprets information from the outside environment and manages all bodily activities. Senses which include sight, touch, taste, smell, and hearing, provide information to the brain. The brain interprets this information, enabling us to give the input it receives meaning. Along with the spinal cord, the brain is a component of the Central Nervous System (CNS). The brain's lobes include: There are four lobes in each cerebral hemisphere, each of which has a specific purpose. The frontal, parietal, temporal, and occipital lobes are the four lobes of the brain.

The frontal lobe: Behind the forehead, in the front of the brain, lie the frontal lobes. Cognitive processes, such as problem-solving, decision-making, attention, intelligence, and voluntary behaviours, are related with their primary roles. The motor cortex, which is in charge of organising and coordinating motions, is located in the frontal lobes. Additionally, it has the Broca's Area, which is crucial for language production, and the prefrontal cortex, which initiates higher-lever cognitive processing.

Occipital lobe: The occipital lobes collect sensory input from the retinas of the eyes, which are subsequently encoded into various visual data. They are placed at the back of the brain, behind the temporal and parietal lobes, and below the occipital bone of the skull. The occipital lobes perform a variety of tasks, such as measuring size, depth, and distance, figuring out colour information, recognising objects and faces, and mapping the visual environment. It houses the main visual cortex, which transmits sensory data regarding location, spatial information, motion, and the colours of objects in the field of vision after receiving it from the retinas.

Parietal lobe: Between the frontal and occipital lobes and above the temporal lobes, at the top of the brain, is the parietal lobe. It is crucial for combining data from the body's senses so that we may create a cohesive picture of the environment around us. Through somatosensory input, these lobes enable us to perceive our bodies. Reading comprehension, number representation, and visuospatial processing can all benefit. It consists of the somatosensory cortex, which collects and interprets sensory data before incorporating it into a mental map of the body.

Temporal lobe: The temporal lobes are called thus because they are situated close to the head's temples on both sides of the brain. Understanding, language, memory development, face and object recognition, vision, and the processing of auditory information are some of these lobes' primary roles. Both the left and right hemispheres of the brain contain a temporal lobe. The left temporal lobe, which is the most dominating part, connected to language, learning, memorization, word production, and verbal memory.
