The human brain is a complex organ that is responsible for controlling and coordinating the body's functions and behaviors. It is divided into two hemispheres, the left and the right, which are connected by a bundle of nerve fibers called the corpus callosum. Despite having many similarities, the two hemispheres have some differences in their functions and roles in the body.
The left hemisphere is responsible for controlling the right side of the body and is often referred to as the "logical" hemisphere. It is responsible for language and communication, as well as analytical and logical thinking. This hemisphere is also involved in tasks such as reading, writing, and math. In general, the left hemisphere is more focused on verbal tasks and is responsible for processing language, both written and spoken.
On the other hand, the right hemisphere is responsible for controlling the left side of the body and is often referred to as the "creative" hemisphere. It is involved in tasks such as spatial awareness, recognition of patterns and visual images, and understanding music and art. This hemisphere is also responsible for processing nonverbal information, such as facial expressions and body language.
Both hemispheres work together to create a well-rounded and complete understanding of the world around us. For example, when we read a book, the left hemisphere processes the words and the right hemisphere interprets the emotions and imagery depicted in the story. Similarly, when we play a musical instrument, the left hemisphere processes the notes and rhythms while the right hemisphere interprets the emotion and expression in the music.
In conclusion, the two hemispheres of the brain have distinct functions that are essential for our overall cognitive abilities. While the left hemisphere is responsible for language and logical thinking, the right hemisphere is responsible for processing nonverbal information and creativity. Together, they work to create a balanced and comprehensive understanding of the world around us.

There are few direct studies of differences in brain development between girls and boys, and few to none on ethnicity. Social competence in children and adolescents. Right Brain By Hemispheric lateralization is the idea that both hemispheres are functionally different and that certain mental processes and behaviors are mainly controlled by one hemisphere rather than the other. Below the arachnoid mater is the cerebrospinal fluid, or CSF. Trends in cognitive sciences, 10, 117-123. Neuroscientists are suggesting that social priming influences activity and processing in the amPFC, and that this area of the prefrontal cortex modulates mimicry responses and behavior.

The pons helps control breathing rhythms. The peripheral nervous system PNS is composed of spinal nerves that branch from the spinal cord and cranial nerves that branch from the brain. Each lobe may be divided, once again, into areas that serve very specific functions. Clinical neuropsychology of attention. The brainstem connects to the spinal cord and consists of the medulla oblongata, pons and midbrain.

Brain Lateralization Psychologists now consider functions like language, spatial processing, and certain broader tasks to have lateralization. Left hemisphere damage has many effects on language production and perception. More specifically here is a nice list of the stages of learning to read from birth to 13 years old: As for a second language, there are numerous studies that show babies have amazing ability to absorb language during age 1-3 years old — if you have the opportunity to raise your child in a bilingual environment go for it! The frontal lobe is divided into a lateral, polar, orbital and medial part. Structures such as the amygdala, cingulate gyrus, hippocampus, hypothalamus, ammillary body, nucleus accumbens, orbitofrontal cortex, and thalamus are all structures of the limbic system. The skull is formed from 8 bones that fuse together along suture lines. This area has been found to be underactive in people with autism and the degree of under-activation is highly correlated with the degree of social impairment Schultz et al. Just because you have a classroom full of students who are about the same age doesn't mean they are equally ready to learn a particular topic, concept, skill, or idea.

Doctoral dissertation, University of North Carolina at Wilmington, Wilmington, NC. Although this simple task is automatic for you, it takes a lot of concentration for them. Such changes are not found for children with dyslexia, and their reading skill does not become automatic and effortless. Yuan from the University of Arizona found that larger prefrontal cortex volume and greater PFC cortical thickness were associated with better executive performance. Reading to your children early and often is a great way to help introduce them to language.

The ability to read is also enhanced by the development of the auditory cortex and the development of skills involved in remembering what is taught and applying that knowledge to real problems. So one would think there would be a pair of vertebral veins and internal carotid veins. The internal carotid arteries branch into the skull and circulate blood to the front part of the brain. Through the central nervous system, the brain sends and receives signals throughout the body. Hi Emil, could I use certain parts of this beautifully written article to show parents in my neighbourhood, to pay more attention to what the school system is doing to their children?

Some studies have suggested that the larger brain, higher white matter volume and disrupted gray matter cellular columns may contribute difficulty that a person with autism has in integrating information and generalizing this information to new situations Schultz et al. It is the largest white matter structure in the brain and allows the two hemispheres to communicate. Forty Studies that Changed Psychology: Explorations into the History of Research. Not all functions of the hemispheres are shared. And by the same organ we become mad and delirious, and fears and terrors assail us, some by night, and some by day, and dreams and untimely wanderings, and cares that are not suitable, and ignorance of present circumstances, desuetude, and unskillfulness. Other functions relate to vision, hearing, touch and other senses.
