Posterior parietal cortex

processed only by the spinal cord, resulting in a fast reflex action by the body. The second pathway is known as the spinothalamic pathway where the noxious stimulus is transmitted from the spinal cord to the thalamus and finally to the somatosensory cortex in the brain. As it involves the brain this the pathway involved with pain perception.…

et al, 2003). It is a hierarchical model which governs the control and coordination of information processing. The executive functions emerge from infancy and develop swiftly during the preschool years. Dynamic brain changes within the prefrontal cortex (PFC) are consequently closely associated with the development. Throughout the essay, I am going to focus on the childhood development of cognitive flexibility, inhibition control, planning, and working memory among the broad range of executive…

Parkinson’s disease is a hazardous disease and one of the most common diseases in US, about one million people live with it. It is a progressive movement disorder which means that the symptoms may get worse over time. Till now the cause is not identified or known .There is no cure but there are treatments to reduce the symptoms by medications and surgery. WHAT IS PARKINSON’S DISEASE? It is a brain disorder affecting brain cells in the brain. Parkinson’s affects neurons in an…

such extraordinary cognitive abilities, such as self-awareness, when many other species use tools, hunt, live in unstable environments, engage in group living and navigate complex social hierarchies, and perform elaborate mating displays (Flinn et al., 2005). The gorilla represents a particularly difficult anomaly for these models; despite documented tool use (Breuer et al., 2005) and social group living (Cipolletta, 2004), gorillas fail to consistently demonstrate mirror self-recognition…

part of the brain is called the cerebrum. The cerebrum is divided into two cerebral hemispheres, which develop from the forebrain. The hemispheres have the cerebral cortex which contains ten billion nerve cells. Underneath is the brainstem, and behind that is where the cerebellum is. The outermost layer of the cerebrum is the cerebral cortex is divided…

The Central Nervous System is the most important organ system in the human body because it is how we control our body. It consists of the spinal cord, nerve cells, and parts of the brain (Organ System Skit). “The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain” (How Does the Nervous System Work? NCBI). In addition, when the body wants to move, the brain sends a message to the…

One of the many diseases caused by faulty cell-to-cell communication is Alzheimer’s disease. This disease causes many cells in the brain to die. Therefore, as more and more of the cells die, it causes the brain to shrink. What causes the brain cells to die, which then causes the brain to contract, is the unusual twist of the protein called tau. Tau is a protein in the brain that delivers nutrients and other important elements to the brain cells. The effect of the twisted protein inhibits the…

Positron emission tomography (PET): is an anatomically based measurement that utilizes small radioactive tracers that are able to identify and determine glucose and metabolic levels within the organs of the body. This type of tomography could be used in a concussion assessment to determine the metabolic activities and glucose levels of the brain, as these levels are important and often become altered following a concussion. Functional magnetic resonance imaging (fMRI): is an anatomically…

ACTH-1-39: Product Description ACTH 1-39 is a synthetic polypeptide hormone that consists of 39 amino acids. ACTH 1-39 is commonly referred to as Adrenocorticotropic hormone, corticotrophin, or ACTH. The molecular formula for ACTH 1-39 is C207H308N56O58S1 and a molecular mass of 4541.11 kilo Daltons. The structure of ACTH 1-39 corresponds to the full-length structure of ACTH. The natural Adrenocorticotropic hormone (ACTH) is naturally synthesized by the anterior pituitary gland and its release…

Neurodevelopmental disorders are disorders wherein impairments in neural development lead to deficits in various cognitive and/or social abilities (Reynolds & Goldstein, 1999). Historically, researchers have often assumed that human cognition is served by numerous “modules”, each of which performs a specific cognitive function. It is typically argued that each module is supported by a specific brain region whose evolutionarily-defined characteristics confer neural properties that facilitate…
