Week 2 Task: Brain Development

It is still not fully understood whether or not the action of certain tasks is actually dependant on both of the brain hemispheres, because they both appear to have control over some tasks. An example of this, is the left hemisphere which is said to be responsible for the analytic part of the tasks, such as reading and making calculations. Within many individuals, it is also the dominant centre of language

According to the theory of lateralisation developed by Robert Sperry and Robert Ornstein, the cerebral cortex in the two hemispheres perform the same motor and sensory functions but each of the hemisphere is specialized for different tasks. As the brain develops, the left hemisphere is superior in doing tasks that involve speech, language, reading, and writing. The right hemisphere shows superiority in tasks that involves creativity, intuition, facial recognition, non-verbal imagery, musical recognition, sense of direction, play and sports, learning experience and risk-taking. Lateralisation is developed for the task that is done, that is the right hemisphere is used for a particular function. This decision is influenced by genetics, childhood learning experiences and

Right hemisphere specialises in special judgements and the left can describe its perceptions in words. Normally they work together as one.

*. By repeatedly obtaining brain scans of the same children for up to four years, researchers found that the children’s brains experience undergo dramatic anatomical change between the ages of 3 and 15.

The right side of the brain is responsible for putting information together eg. information recived from eyes-if you see a flower information goes from eyes to the right side of your brain , firing neurons, putting information together so you are able to say "I can see a flower".The left side of the brain analyses information which is collected by the right side of the brain. It

The largest part of the brain "the cerebrum" is divided in to two hemispheres, each hemisphere have different functions and responsibilities in memory, reasoning and language. The two hemispheres are in close communication with each other via corpus callosum .

According to (Woolfolk & Margetts, 2013), the brain begins to mature even before birth and it continues to mature throughout life. According to (Jetha & Segalowitz, 2012) all the brain functions do not mature at the same rate. A child with highly advanced verbal skills may develop gross and fine motor control more slowly and have trouble learning to write clearly (Jetha & Segalowitz, 2012). Learning differences are also related to genetics, temperament and environment (Thierry, 2008). As child born it has a function govern like their heartbeats, eating and sleeping.

In class on 9/18, we discussed the structures of the brain and how each part works. The brain has so many parts that it is almost impossible to remember all the parts and their functions. The brain is very complex, but the most interesting thing that was talked about was the two different hemispheres. We discussed how the right hemisphere controls the left side of the body and vise versa I found it very interesting that the left side of the brain controls more of our logic and grammar, and the right side of the brain controls more emotional expressions. When Dr. Yarnell discussed her story of her friend and her friend’s husband getting in a fight I think the way she told her to help resolve it was very interesting. Her response was to move into her left side

The results of this study show us the brain is not in fact symmetrical and the two hemispheres in the brain work in different ways. The left hemisphere is known to play the dominant role, which is in control of all complex behavioural and cognitive processes as for the right hemisphere it only plays a minor role. This report will further analyse how different the two hemisphers is the dominant side of the brain.

From the ages of two and six years of age the average brain gains ten percent in mass (Manis, 2016). Between the ages two and three, the average child possesses almost fifty percent more synapses than the average adult. However, pruning during childhood and adolescents reduces these levels to the normal adult levels. During early childhood, children also improvement in their neural networks. This is caused by increased growth of dendrites and myelination of axon pathways during early childhood. The part of the brain that shows the most growth during early childhood is the prefrontal cortex. The prefrontal cortex is responsible for problem solving, decision making, and goal setting. Working memory, inhibition of responses or thoughts, and shifting between mental states or rules and tasks is also handled by the prefrontal cortex. These specific areas are especially important during early childhood. These tasks are important because they allow the child to learn how to perform tasks, and promote future academic

In spite of this when glancing further into the human mind, both hemispheres share special lobes which each possess distinct abilities. Firstly, there is the frontal lobe which can be located at the foremost part of the skull and manages a persons emotions, reasoning, problem solving, speech and movement (motor cortex). Secondly is the temporal lobe that can be pinpointed near the bottom of the skull right above the cerebellum, and has to do with the perception and recognition audio stimulants and memory (hippocampus). Next is the occipital lobe found at the very back of the skull, as it handles an individuals many aspects of vision. Lastly, there is the parietal lobe that takes charge of the perception of stimuli like touch, temperature,

The cerebral cortex is split into two cerebral hemispheres (the left and right hemispheres). Sometimes the right hemisphere is related to creativity and the left hemisphere is related to logic abilities. It is divided into four sections called lobes, the frontal lobe, parietal lobe, occipital lobe, and temporal lobe. This is the largest part of the brain. The cerebral cortex is associated with determining intelligence, influencing your personality, motor function, planning and organization, processing sensory information and language processing. The cerebral cortex has sensory as well as motor areas therefore it is responsible for processing sensory information and motor functionality responses.

The left hemisphere controls the right half of the body that controls language and logical tasks. The right hemisphere controls the left half of the body creativity and emotions. Split-brain reveals that depending on what side of the brain is damaged, the two brain hemisphere may have information sharing problems, due to the separation of the corpus callosum . "a split-brain patient looking at an image through the left eye may not be able to name the picture because the information is only available in the largely nonverbal right hemisphere".

Infant learning and brain development is fragile and contingent upon numerous intrinsic and extrinsic factors. The most critical time frame for infant brain development is from the second trimester to the first three months of life (Marshall, 2011). During this time, neural pathways are forming, areas of the brain are maturing, and brain development is rapid. From infancy until the age of 3 years, neural pathways are still being formed in response to stimulation and for this reason, it is extremely important for caregivers and parents to be aware of the many factors that can influence brain development in infants (Marshall, 2011).

Activities within the head are like unseen milestones. They happen in stages and in different parts of the brain. Among other milestones is the peaking of visual cortex at about three months and at nine month the hippocampus which is responsible for memories become fully functional. The completion of these internal milestones helps to prepare the child for the environment. At t his point the child becomes like a sponge ready to absorb everything it comes into contact with. Patricia Kuhl of the University of Washington studies the auditory maps and finds that the auditory starts out waiting ready to pick up anything it is exposed to but reaches completion at twelve months. This explains why it is easy for children to pick up a new language. Even though the brain is quick to take on new jobs, it is very organized as found out by Patricia Kuhl. Each neuron knows its job and do not intervene
