The largest independent organ in the brain

#Cerebrum Structure#

The cerebrum is the largest part of the human brain and accounts for 85% of its weight. It also performs many important functions. The cerebrum, which is structurally divided into left and right hemispheres that are responsible for different aspects such as cognition, emotion and sensory processing, is split in two.The cerebrum is made up of several major structures including the basal-ganglia and limbic system. The outermost layer of cerebrum is the cerebral cortex. It is divided into 4 main lobes.

1. **Frontal Lobe**: The frontal lobe, located at the front of your brain, is responsible for higher cognitive functions, such as problem solving, reasoning, and emotional regulation. It is also important for voluntary motor control.
2. The parietal cortex is located behind the frontal cortex and processes sensory information such as temperature, pain, and touch. It integrates sensory input for spatial awareness and navigation.
3. **Temporal Lobe**: Located on the sides, the temporal is involved in the formation of memories and emotions. The temporal lobe contains the hippocampus. This is a memory-building structure.
4. **Occipital Lobe**: The occipital is located at the rear of the brain and is responsible for processing visual information. It is responsible for interpreting signals from the eye and allows the perception of colors, shapes and motion.
Asymmetry in functional terms
The concept of functional asymmetry or lateralization is one of the most fascinating aspects to the cerebrum. Each cerebrum hemisphere has a different function. In most right-handed people, the left side of the cerebrum is responsible for processing language, while the right side is more concerned with spatial reasoning and creativity. This division of work allows for a more efficient processing information.



#Limbic System#

The limbic system is often considered a part of the cerebral cortex. It plays an important role in emotions and memory. The limbic system contains the amygdala which is essential for processing emotions, and the hippocampus, an important structure for memory and learning. The interaction between the cerebrum, limbic system and our emotions is crucial.Cerebrums are also known for their ability to undergo Neuroplasticity. This is the brain's capacity to reorganize by creating new neural connections over time. This adaptability allows people to develop new skills, recover after injuries, or even change their behavior in response to experiences. Neuroplasticity emphasizes the dynamic nature and importance of mental engagement and learning.

The brain plays a role in a number of cognitive functions including:
Attention: The ability to concentrate on a specific stimulus while ignoring other stimuli.
Memory: The processes that are involved in encoding information, storing it, and retrieving it.
**Language** : The ability to express and receive language, which is primarily located in the left hemisphere for most people.
**Executive Functions**: Higher-level processes, such as decision making, planning and social behavior are controlled by the frontal cortex.
Brain disorders can lead to significant impairment. Brain function can be impaired by conditions such as Alzheimer's, strokes and various dementias. The symptoms can vary from memory loss, difficulty speaking and emotional regulation to personality changes and personality disorders.



#Conclusion#

The cerebrum, as the largest organ of the brain and the most independent one, is essential to our everyday functioning and quality of life. The complex structure of the cerebrum allows us to interact, think and feel about our environment. Understanding the role played by the cerebrum sheds light not only on human cognition and behavior, but also highlights the importance of brain function and the ability of the brain to grow and recover throughout life. Understanding the intricate workings of our brains and ourselves is possible by understanding the cerebrum.
