functioning. Cognitive Functioning The cerebral cortex is divided into four lobes as well as into left and right hemispheres. Martinez (2010‚ pp.237) states that‚ “The cerebral cortex is the anatomical origin of the mind’s higher-order functions—reasoning‚ intelligence‚ creativity‚ and problem-solving—as well as the coordination of sensory input and motor control that helps us relate skillfully to our environments.” By segregating each structure of the cerebral cortex a greater understanding is achieved

language faculty seems to be located in certain areas of the left hemispheric cortex in most healthy adults. A special branch of linguistics‚ New medical imaging techniques such as PET and fMRI have allowed researchers to generate pictures showing which areas of a living brain are active at a given time. In the past‚ research was primarily based on observations of loss of ability resulting from damage to thecerebral cortex. Indeed‚ medical imaging has represented a radical step forward for research

Underneath the cerebrum lies the brainstem‚ but behind that is where the cerebellum can be located. On the other hand the outermost layer of the cerebrum is the cerebral cortex that happens to contain four lobes which include the frontal lobe‚ parietal lobe‚ temporal lobe‚ and the occipital lobe. However the human brain can be broken it many more parts but it will always trace back to these six parts. Although this is

Which of these is/are (a) component(s) of the somatic nervous system? Ventral roots Motor cortex Ventral horn All of these are component of the somatic nervous system Mechanoreceptors that respond to changes in blood pressure are called Baroreceptors Assessing spinal nerve damage may involve the use of a vibration fork that is tapped along

The human brain has five divisions. They start forming in the vertebrae embryo as the tissue that eventually develops into the central nervous system. The first developments of the brain are three swellings that appear at the anterior end of a fluid filled tube. These swellings eventually become the forebrain‚ midbrain‚ and hindbrain. What happens is‚ the forebrain swelling grows into two different swellings and so does the hindbrain swelling. This is what makes up the five divisions of the brain

The means by which the brain performs are referred to as neuroprocesses‚ which are related to learning and memory. The brain is the center of every function of the body that controls functional learning and memory and how the two are interdependent. Learning occurs when the memory is stimulated. The memory is activated once learning has taken place. With knowledge at the center of attention‚ it is imperative to stimulate the brain through lifelong learning to achieve longevity and quality of life

THE CENTRAL NERVOUS SYSTEM Every behavior begins with biology. Our behaviors‚ as well as our thoughts and feelings‚ are produced by the actions of our brains‚ nerves‚ muscles‚ and glands. In this chapter we will begin our journey into the world of psychology by considering the biological makeup of the human being‚ including the most remarkable of human organs—the brain. We’ll consider the structure of the brain and also the methods that psychologists use to study the brain and to understand how it
