To explore cognitive development in terms of the specialisation of function in specific cortical structures, one must outline association between structural differentiation and functional specialisation. The typically developed adult brain shows predictable associations between specific cortical areas with particular cognitive functions. Prior to maturation, the developing brain demonstrates increasing differentiation in both structure and function of cells, with structural changes directly affecting functional capacity. The structural differentiation[1] of neural pathways through the processes of dendritic growth, myelination and encapsulation result in cortical areas highly efficient in supporting particular types of information, or specialised functions. The underlying reasons for the organisation…
The human brain is one of the most complex and fascinating parts of the body. The major regions of the brain are separated into three layers called the central core, the limbic system, and the cerebral hemispheres or otherwise called the forebrain, midbrain, and hindbrain. The forebrain houses the cerebrum, thalamus, and hypothalamus. The midbrain houses tectum and tegmentum. The hindbrain houses the cerebellum, pons, and medulla. From here the brain is divided into five major divisions. They are called the telencephalon (forebrain), the diencephalon (forebrain), the mesencephalon (midbrain), the metencephalon (hindbrain), and the myelencephalon (hindbrain).…

The command center of the human nervous system is the brain. The sensory organs send information to the brain, which then sends output to the muscles. The largest part of the brain is the cerebrum. Underneath the cerebrum lies the brainstem, and behind that sits the cerebellum. The outmost layer of the cerebrum is called the cerebral cortex, which has four lobes. There is a frontal lobe, parietal lobe, temporal lobe, and occipital lobe. The brain develops from three sections known as the forebrain, midbrain, and hindbrain. There are two hemispheres, the left and the right. These two hemispheres are connected by a bundle of nerve fibers called the corpus callosum.…
Cerebrum- is the anterior and largest part of the brain, consisting of two halves or hemispheres and serving to control voluntary movements and coordinate mental actions.…
Brain development in infants is influenced by a number of different factors, including nutrition, their genetics, interactions with their parents, physical activity, and other experiences. In the past, scientists believed that children's brains were predetermined to a great extent in terms of how they would develop. However, scientists now know that an infant's experiences help determine how connections are formed and which pathways will develop in the brain. rather than being predetermined, an infant's brain is a work in progress, influenced not only by his or her genetics, but also the surrounding world.…
The largest portion of the human brain is the cerebrum. Also known as the cortex, the cerebrum is involved with higher brain functions like thought and action. The cerebral cortex has four lobes – the frontal lobe, the parietal lobe, temporal lobe, and the occipital lobe (“Brain Structures and their Functions,” n.d.; “Frontal Lobe - The Brain Made Simple,” n.d.).…
The process of trying to quit smoking is harder than one could ever imagine. This addiction will have you on a terrible emotional roller coaster where you’ll begin to have mixed emotions about what to do. People already smoke cigarettes for totally different reasons, such as loosing weight, relieving stress, and to control unwanted feelings. In the beginning your negative emotions will begin to over power the positive. On one hand your intellect knows that smoking cigarettes is a terrible thing to do to your body and your environment, and you want to quit, but on the other hand the biological brain has been formed to seek gratification and avoid grief. When it comes to trying to quit smoking several brain functions and structures are involved with this process as well as your environment and heredity. This paper will discuss the brain structures and functions that are involved with your behavior and emotions to drive people to smoke and quit smoking. And it will also discuss weather or not smoking is hereditary and how much effect the environment has on an individual who is trying to quit smoking.…
To begin with, the changes that the young brain undertakes to create a complex organ are ultimately much faster and mature by the end of the long session. The neurons used to send signals around the body consist of nerve fibers, which slowly become insulated with Myelin, boosting the Axon’s transmission speed up to a hundred times (Dobbs 2011). The dendrites, which are root-like stems connected to the cell body, begin to grow richer and stronger as they use heavier synapses to pass information to another (Dobbs 2011). The less commonly used synapses consequently begin to weaken. It is called synaptic pruning, which causes the brain’s cortex to become thinner yet more proficient (Dobbs 2011). “Physiologically, adolescence brings a peak in the brain's sensitivity to dopamine, a neurotransmitter that appears to prime and fire reward circuits and aids in learning patterns and making decisions” (Dobb 2011)…

The first eight years of a child’s life are not only the most important years of a child’s life, but also the most rapid period of human development throughout a human life. These years are critical to the emotional and physical growth of a child. By the age of four, half of a person’s intelligence potential has already been developed and early childhood experiences can have a lasting effect on personality, behavior, and learning. (Early, 2001) These first eight years of life are broken down into the first two years, early childhood, and middle childhood. Throughout these three stages of life, the brain does most of its developing and determines the life that person will lead. The developing of a child’s brain falls upon the interactions and experiences a child has with its parents and any other primary caregivers in the beginning of life.…
With the changing of society through technology, it is hypothesized that Digital Native’s (current generation that has grown up on technology) brains are physically different than other generations due to the stimuli they received growing up on technology. It was previously believed that your brain could not be physically changed after about the age of three. But through studies and research it has been proven differently. Research has shown that in fact the brain is constantly creating new brain cells and reorganizing itself. One of the earliest experiments on testing brain altering was done in a study on rats. It was shown that when rats were put in different environments, their brain sensory areas and layers changed quite quickly. Also, steady growth in brain alteration was monitored throughout the entire testing. There are also other many other studies in which it shows the brain can adapt and change to different situations.…
