Essays on Cerebral Cortex

The brain is the most important organ in the human body since it is the one responsible for the interpretation of senses, intelligence, controlling behavior and movement. However, most of the neuroscientists have been unable to conclusively determining the relationship between the various parts of the brain and the outward behavior. For instance, many neurosurgeons have used studies on the preferred hand in the prediction of the dominant part of the cerebral hemisphere. According to Weiten and McCann (2013), cerebral hemispheres are identical in appearance. However, they differ significantly in terms of the structure and functions. The brain lateralization ...

Speech Disorders

Formation of speech is one of the basic characteristics of the general development of the child. Speech for the child is the most important means of communication with the outside world, interacting with others, as well as information for the development of cognitive activity and thinking. Therefore, the development of speech is closely connected with the formation of all other mental abilities. Signs of the backlog in the development of speech is a reason for immediate treatment and a visit to the doctor (pediatrician, child neurologist, otolaryngologist, a child psychiatrist, a speech therapist, psychologist). This is especially important, because ...

Abstract

The phenomenon of apparent motion occurs when two stimuli are separated by a flash or a blank in which the brain creates the effect of movement. It can be compared to the effects of moving pictures, for example, in which a series of still photographs are put together in such a way that the image appears to be moving. The purpose of this research is to assess the phenomenon of apparent motion in terms of the interstimulus interval, the gap between two stimuli that most accurately conveys movement to the perceiver. The study used five different dot spacings, and ...

A. The human cerebral cortex is divided into three main areas: sensory, motor and associated areas (Association Cortex, 2016). Sensory areas belong to the peripheral nervous system. They extend from the spinal cord to the receptor cells located in all parts of the body. The primary function of sensory area to carry impulses from the receptor cells to the brain for interpretation. These impulses can be those of sensations like touch, pain, smell, taste and sight. The motor area or the primary motor cortex is located in the interior part of the brain at the central sulcus. Its pyramidal ...

While most people are familiar with a number of leading theorists in psychoanalysis, particularly Sigmund Freud, and possibly Adler and Jung, most people would not be familiar with Karen Horney, considered to be the “fist psychoanalytic feminist” (Hergenhahn & Henley 525). Horney disagreed with several concepts introduced by Freud, especially his focus on unconscious sexual motivation and the division of the self into 3 parts: id, ego, and superego. She believed that social experiences had a greater influence on the creation of self. During the Depression, she found that her clients’ problems were caused by unemployment and the inability to ...
