I will describe previous research and then investigate how REM and memory are associated in young people and in older people. In some ways, the sleep patterns of these two groups are very similar, but in some ways they are not. 1a. In the normal brain, REM sleep is the stage of sleep during which the body tends to be very relaxed, with little to no movement of the muscles. However, it is possible to observe occasional slight movements, called twitches, while one is in the REM stage of sleep. Despite

After reading “The Myth of Multitasking,” I found multitasking to have a negative impact on the quality of how work is done. Rosen expresses many reasons why multitasking has a negative impact on today’s individual. When it comes to a 21st century average adult, being busy is just how it works, which is why we feel so pressured to multitask all the time. Though in this day and age, deadlines are always around, it doesn’t give us an excuse to allow ourselves to do inefficient, low quality work. Even

Introduction Functionality of Upper limb is fundamental for the execution of basic activities of daily living (ADL) like eating, drinking and personal hygiene. One of the most common sequelae in central nervous system injury is impaired upper limb function, which is affected in more than 80% of stroke cases (1) . Stroke is the leading cause of disability in adults in the United States, affecting an estimated 730,000 people per year. It is therefore a major and increasing health care problem and

Genetics of Late Onset Alzheimer’s Disease Late-onset Alzheimer’s disease (LOAD) is a frightening and expensive disease. Studies show that in 2010 over $215 billion dollars were spent on dementia care, and the condition is among one of the highest diseases that people currently fear getting, second only to cancer (PBS). Scientists are actively searching for clues to determine cause of this disease. Due to the fact that the genetics and risk factors of late-onset are not fully understood, scientists

Understanding how opioids work in the brain is essential. Opioids connect to receptors in the brain, then they send signals to the brain of the opioid effect which blocks pain, slows breathing, and has a general calming and anti-depressing effect. The chemical structure of opioids mimics that of a natural neurotransmitter which is why the activation occurs. However, opioids are unable to activate nerve cells as natural neurotransmitters do, leading to abnormal messages being transmitted through the

and assistances the transferring of neural messages from the brain to the spinal cord. (In the lower part of the brain stem) 2. Cerebellum The cerebellum is responsible for voluntary activities like running, writing, and drawing. It is essential for balance and coordination. (In the lower area of the brain near the occipital lobe, and the pons) 3. Thalamus The thalamus identifies different sensory information that is transferred to the brain by sensory organs such as ears (auditory), eyes (visual),

Addiction Abstract Brain development of the decision making and critical thinking portions of the brain is not complete until adulthood. Since these portions of the brain are under developed in adolescence and early adulthood riskier behavior is seen during these periods of life than are after the brain completes development. An example of a risky behavior seen in adolescence and young adulthood is drug abuse. Drug abuse is thought to affect the development of the microglia cells in the brain, and increase

Personal Reflection While being in AP Psychology I have realized many different things about the brain and how people's lives can be very affected by different disorders. We have discussed serious mental disorders that people are unwillingly faced with. From people having a simple anxiety disorder to someone suffering with schizophrenia, the brain has the ability to do incredible, yet devastating things. Throughout my experience in the class, it has influenced the ways that I see many

Anatomy of the Facial Nerve The facial nerve is the seventh cranial nerve; it emerges from between the medulla and the pons, and travels through a 30mm intraosseus canal in the skull until it exits via the stylomastoid foramen and the “motor root” of the facial nerve forms the parotid plexus, splitting into 5 terminal branches i.e. temporal, zygomatic, buccal, marginal mandibular and cervical branches and innervates the muscles of facial expression, stapedius muscle, stylohyoid muscle and the posterior

Abstract This investigation explores both short and long term effects of psychedelic drugs on the brain, citing research from fifteen peer-reviewed sources. Within the paper are biological explanations of how psychedelics trigger various effects by interacting with serotonin and dopamine receptors. Following this are case studies in psilocybin mushrooms, salvinorum A, and dextromethorphan. Medical studies administering these psychoactive substances to participants illustrate classic hallucinogenic
