Dopamine & DAT (Dopamine Active Transporter) The central dogma of biology involves the transcription of DNA to mRNA and the subsequent translation of the mRNA to protein. This experiment focused on identifying the Dopamine Active Transporter, commonly abbreviated as DAT. DAT is a consists of 12 transmembrane domains. It is responsible for mediating the reuptake of dopamine from the synaptic cleft back into the cytosol. With dopamine being one of the key neurotransmitters, it is associated with a

Parkinson’s disease is associated with a lack of dopamine in the brain. It affects thousands of people, generally the older population, causing tremors and muscle rigidity (Yahr). Currently, there is no cure and people turn to medication, deep brain stimulation, or fetal brain implants. Every patient is different and reacts differently to the array of treatments. The problem with dopamine is that it cannot simply be injected into the person to serve as a cure because it cannot cross the blood brain

Dr. Shailesh Kantak spoke about the benefits of using Transcranial Direct Current Stimulation (tDCS) to stimulate the brain to alter neurons and increase learning. Brain plasticity occurs in a clinical setting through challenge and dose, where the brain changes to adapt to learning. tDCS has been found, in a cheap and portable way, to be able to stimulate the human brain and temporarily change the functional output in the brain. Cathodal stimulation slows down the brain excitability and anodal increases

The way the cerebral cortex is organized is through different regions that receive and analyze the sensory information. The first is the primary visual cortex, also called the striate cortex, which receives the visual information. The primary visual cortex is located in the back of the brain in the occipital lobe. Then there is the primary auditory cortex which receives the auditory information. This cortex is located in a fissure (a major grove in the surface of the brain) that’s on the said of

Background Glioma is a tumor of the brain that originates in the center of the brain section. The cells that make up a glioma are glial cells, which are the most common cell component of the brain. The gliomas form when the glial cells divide and recreate out of control too rapidly. There are three types of glial cells that can create a glioma astrocytes, oligodendrocytes and ependymal. Each type creates a different type of glioma, and if mixed together can be classified as a mixed glioma (Glioma)

Another portion of the brain related to synesthesia is the mirror neuron system. This system is particularly linked to mirror-touch

Regulatory Behavior Paper Debra Sebastiano PSY/340 May 18, 2015 Professor Mark Schmitz The nervous system is accountable for organizing the body's daily actions. It not only controls the upkeep of regular roles but also the body's capability to deal with emergency circumstances. When talking about the nervous system we are talking about three overall functions, the first function is the sensory function, the second is an interpretative function and the third is a motor function. The sensory

The nervous system is quite complex and includes many types of neurons that have many different functions. However, it is very well organized, and despite its complexity, the organization is actually quite elegant and reflects the functions of its component neurons. The central nervous system is composed of the brain and spinal cord and functions mainly to process information and determine the appropriate responses.The peripheral nervous system is composed of all of the sensory and motor neurons

collaboration of different body systems. The nervous system sends the impulse to muscles and triggers senses to occur. The skeletal system provides support of the body and the muscular system enables movements to take place. The task of eating a hamburger in response to its smell involves the nervous system, skeletal system, and muscular system. The smell of the hamburger triggers impulses of the nervous system. The afferent division of the peripheral nervous system, which involves sensory triggers

of cells with similar functions. Tissues are commonly categorized by the function of the cells that make them up. There are four types of tissues in the human body which are nervous, epithelial, muscular, and connective. The main components that make up nervous tissue are nerve cells or neurons. An important structure of nervous tissue are the neuroglial cells. Neurons are a specialized type of cell that receive and transmit information as electrical or chemical signals. Neurons pass on the information
