The research on rats suggests that adolescent brains may be particularly vulnerable to alcohol-induced memory impairments and learning difficulties. The study conducted with young adults confirms this thesis; when tested under alcohol, people in their early 20s performed worse on a task which involved immediate and delayed recall than people in their late 20s. This data clearly shows the vulnerability of younger subjects to alcohol-induced memory impairments. Young people often experience blackouts-episodes of anterogate amnesia, during which they are likely to engage in risky behaviours, such as vandalism, unprotected intercourse, or violence. Later they have no recollection of their actions. It is suggested that alcohol affects memory formation as it disrupts brain plasticity and interferes with the changes in circuitry which are essential for the learning process. Alcohol use damages hippocampus, the brain region which is crucial for memory formation.
Moreover, repeated exposure to alcohol in adolescence may result in long-lasting changes in brain function later in life (White, 2003). The study conducted with adolescent alcohol abusers reveals that despite their relatively short periods of drinking, young people experienced severe cognitive impairments weeks after they stopped drinking. These changes are due to sensitivity of adolescent hippocampus to the neurotoxic effects of long-lasting use of alcohol. The data suggests that the subjects who abuse alcohol in their early adolescence are more vulnerable to hippocampal damage in the future.
Use of alcohol in adolescence severely affects the establishment of new memories as well as memorization skills and learning capacities. Due to common blackouts, adolescent drinkers are likely to engage in risky behaviours. Moreover, extensive alcohol ...Download file to see next pagesRead More

Exploring the Brain Responses
...Exploring the Brain Responses Aim The aim of these two experimental studies is to show that the brain responds differently to a treatment of the conditions set. Introduction This is a cellular biology study of the brain through some experiments. The experiment carried out will show how our behavior and the environment affect our brain. The two experiments are done on the human and rat using an inducement of rTMS and stimulants respectively. The experimental study has the hypothesis of the inducement of either the rTMS or the stimulants triggering the dopamine production. In the two experiments, the brain is induced with rTMS for patients with...

The Brain. Mesencephalon. Myelencephalon
...? Brain is the most complex organ inside the human body. It is the control unit of the entire body and directs all the internal and the external actions. The brain is divided into five major structures each of which is described below. Mesencephalon: The Mesencephalon is located in front of the pons and in between the forebrain and the hindbrain. It is a very important part of the brain as it plays a crucial role in proper coordination of spinal cord and the brain in the central nervous system. It is subdivided into two regions: tectum and tegmentum. Tectum and tegmentum are the dorsal and ventral parts of Mesencephalon respectively. The tectum is made up of a number of pairs of nuclei which have a particular function. Tectum... is...

This is a disease which can bring alteration to the chemistry of a brain and can affect the personality of a person in a bizarre manner. Here, the person who is schizophrenic has malfunctioning in the working system of nervous system. According to (Fisher,2000)“Schizophrenia results in varied and abnormal responses compared to those of normal, healthy individuals. The brain of individuals with the disease endures such changes that their basic functions and operations are altered”. With the emergence of schizophrenia, the patient displays delusion, hallucination, depression...

The Brain and Consciousness
...The Brain and Consciousness Brain stem The brain stem connects the nerves flowing up from the brain stem in the back bone to the functioning centersof the brain. While the brain stem is broken down into many different sub-areas, the main function seems to be to connect the thought centers of the brain with the pathways / organs / muscles which are affected by those thoughts. While this analogy is limited, if the brain is a computer, the brain stem could be through of as the CPU. All the sensory input coming from the body, and the thoughts being sent out, responsively and proactively, are...

Caffeine and the Brain
...than those of prescribed drugs. Caffeine produces similar symptoms like those caused by prescribed stimulants. Even a small dose can affect the brain and nervous system. It also acts on the heart, bladder and muscular movements. Ingesting small doses, however, does not result in problems. Persons who take coffee everyday take a longer time to get a certain effect when compared with non drinkers or occasional users. Larger doses can result in nervousness, palpitation, nausea, insomnia and headache. There are other adverse effects associated with larger doses. Persons using the drug for the first time and ingesting large doses may end up having caffeine jitters, convulsions and even tachycardia. Taking extra large doses...

Lateralization of the Brain
...Here Here Here Here Lateralization of the Brain A recent study by Marc Schmidt (2008) investigatesthe role of lateralization in the brain as it relates to information processing systems. It has been suggested that brain lateralization is an adaptive strategy that allows for multi-tasking, or the operation of two tasks at once. We will examine Schmidt’s study and will determine its contribution to the investigation of brain lateralization as a task adaptation. The author describes research that supports the hemispheric specialization, or lateralization, of the vertebrate brain. This feature is also found in many other species, but most reliably in...

Stuttering and the Brain
...s School Topic Stuttering and the Brain About 55 million people around the world are suffering from stammering disorder, and researches on various levels have been going on for years now to find out concrete reasons behind the disorder1. Despite persistent efforts, the causal connections with a 100% validity rate haven’t been able to drawn by the researchers. However, up till now researchers have established that those people who often stammer are found to be using the right side of their brain instead of the left side, which implies that the left side of the brain remains disrupted causing implications for the brain. Also the auditory cortex remains affected where the...

Motivation and the brain
...Motivation to quit smoking Smoking can be described as a practice in which tobacco or bhang is inhaled in the body after the substance has been burned. Many inhale these substances for recreational purposes. Nevertheless these substances are addictive and if someone becomes deep smoker, he/she has a higher susceptibility to various diseases that are caused by substances in tobacco e.g. nicotine and cannabis. Some of the diseases that are associated with the vice include heart disease, cancer, high blood pressure etc. Many of the addicts have tried to quit to no avail. This has agitated a deep research to determine parts of the body that are involved in increasing motivation to quitting smoking (Noonan, 2011). Brain plays...

The Brain
...Brain and Neurology Brain and Neurology Brain Size and Consciousness: The assertion regarding human brain to be more conscious when the size of brain is relatively larger can be arbitrary. This can be well-understood in the context of mammals. Considerably, elephants have larger brains and monkeys have smaller sized brains but this does not state that monkeys are less conscious than elephants. Similarly, humans in the early ages had relatively larger brains than in the present time. This does not affect the consciousness of humans but rather the intellect and capability of gaining more knowledge. In case, the humans are more likely to gain their brain sizes, they will end up in having increased capability of becoming knowledgeable... of...

Motivation and The Brain
...Motivation and the Brain affiliation The brain is the central coordination engine for the whole body systems, it has various structures and functions that are necessary to initiate and sustain the motivation for healthy eating (Wickens, 2005). Food consumption is mediated by a complex connection of vital body chemicals such as serotonin and endorphins that are markers for pleasure and satiety. These two chemicals combined are essential in determining the level of motivation for the ingestion of food. The brain functions to sustain the equilibrium of serotonin and endorphins activities as a way of promoting positive eating habits. There are a number of intrinsic and extrinsic...
