Want to get to know the best parts of the brain? If your answer is yes, then this blog will give you all the information about it.
The human brain is divided into two hemispheres, one for each hemisphere. Although these hemispheres are always in contact, the two hemispheres are responsible for their own activities.
What does the cerebral hemisphere mean?
The human brain is divided into two hemispheres, one on the right and one on the left. All animals have such brains. The cerebrum is the part of the brain responsible for conscious thoughts and voluntary actions and is made up of these two hemispheres. Therefore, the two hemispheres of the brain are called the cerebral hemispheres.
The cerebral hemispheres are divided into six areas.
Gray matter, white matter, and lobes make up each hemisphere of the brain that performs different functions:
- Cerebral Cortex: The cerebral cortex is the outer gray matter layer of the brain, which is composed of the outer gray matter layer of each hemisphere. According to decades of neuroscience research, the cerebral cortex is responsible for almost all cognitive thinking. This outer layer of the brain can be damaged by brain injury, which can impair cognition. The dense layer of white matter beneath the cerebral cortex gets its pigmentation from clusters of neurons with white myelin sheaths that give it its color. According to a new study, neuroscientists know less about the white matter of the brain than they do about the cortex. However, it appears to play an important role in the central nervous system by serving as a link between the brain and brain stem and vice versa. Because of this, white matter connects the cerebral cortex to the rest of the peripheral nervous system.
- Frontal Lobe: Each hemisphere of the cerebral cortex has a frontal lobe, which is responsible for controlling cognition and voluntary action.
- Parietal Lobe: Sensory information such as temperature, smell, and touch are processed by the parietal lobe of the cerebral cortex of each hemisphere.
- Temporal Lobe: The temporal lobes of the cerebral cortex are also important in processing sensory data, especially auditory data related to music and speech. They also surround the hippocampus and the amygdala, two parts of the limbic system that help control learning, memory and emotional responses.
The primary visual cortex of the cerebral cortex, which is responsible for processing information from the physical visual field, is located in the occipital lobe. 6. 6. .
- Corpus Callosum: The corpus callosum is a bundle of soft tissue that connects the two hemispheres of the brain. Above the cerebellum is a single canal of the corpus callosum, which connects the two hemispheres of the brain.
What is the difference between the right and left hemisphere?
According to scientists, the lateralization of the cerebral hemispheres is true. In other words, according to neuroanatomy, both hemispheres of the brain work together to perform their different functions.
- The other side of the body is controlled by both hemispheres and vice versa. When it comes to movement, the brain works in a mirror image, meaning that each hemisphere controls a side of the body that is different from the other. When the left side of the body is active, MRI clearly shows increased activity of cortical receptors in the right hemisphere. When the left side works, the left hemisphere and the right side of the body also work.
- Left and right hemispheres have clear perceptual accentuation. The left and right hemispheres of the brain have been shown to be responsible for different aspects of cognitive processing. The left hemisphere is known to be responsible for language functions such as grammar and speech. Scientists also believe that the left hemisphere is better at seeing difficult objects and applying neutrality and moral principles to situations. On the other hand, the right hemisphere appears to be important for understanding abstract or discrete stimuli and integrating them into a coherent whole. Both sensory stimuli and abstract concepts can be considered in this context. Both hemispheres must work together to develop comprehensive knowledge and problem solving.
- Left and right people can connect. Note that the hand can affect the hemispheric combination between the two hemispheres. For example, in right-handed people, the left hemisphere is dominant in language processing. Language is handled by both hemispheres, say those who prefer to use their left hand. In some cases, the right hemisphere is more active.
A common misconception is that different parts of the brain control completely different processes, which is not true. Conventional opinion suggests that the left hemisphere is responsible for math and science, while the right hemisphere is responsible for creativity and artistic expression. The scientific evidence does not support the idea of functional asymmetry in any way.
