The goal of this thesis was to show that brain perfusion SPECT can help to clarify important issues regarding the prodromal MCI stage of AD and relapsing NMO. Specifically‚ this thesis shows: 1. That based on recently published literature‚ brain perfusion SPECT is a valid biomarker of neuronal injury in MCI due to AD in both clinical and research settings‚ equivalent to FDG-PET but less expensive and more accessible worldwide (Chapter 2). 2. That brain perfusion SPECT combined with graph theoretical

substance acts on the brain. A popular definition of addiction is progressing from liking the substance to needing the substance and constantly seeking it out despite any negative consequences the user may experience. There is still much research to be done in the field of addiction especially alcoholism. The mechanism alcohol utilizes is disinhibition of GABA in the brain. GABA is an inhibitory transmitter and when it is being disinhibited it is being released more into the brain. This increase of

During the growth and development of the brain‚ the physical structures and neural pathways of the brain can change dramatically. Various regions of the brain may grow‚ new synapses may be created‚ or unused synapses may be pruned off. The ability of the brain to change and adapt has been called plasticity. In the TED talk “The Growing Evidence of Brain Plasticity”‚ Dr. Michael Merzenich makes a case for brain plasticity and proposes ways this ability can be used to help various mental disorders

The Ten Principles and Brain Development At birth there are about 100 billion brain cells produced and they are beginning to connect with each other. At the first week of age‚ brain development starts with conception. It is important to reach the age of an infant and practice the ten principals. In the early years‚ young brains produce almost twice as many synapses as they will need. By age two‚ the number of synapses a toddler has is similar to that of an adult. By three the child has twice

TWENTY-FIVE BRAIN-FRIENDLY STRATEGIES 1. Music alters brain chemistry. It can be used to energize‚ calm‚ or increase effective functioning on tasks. It can be used as a call back‚ as a timer‚ a transition‚ or to constructively increase suspense or tension. 2. Start class sessions with a greeting‚ an overview‚ or some other class ritual. 3. Begin each class session with meaningful information and activities rather than taking attendance‚ making announcements‚ or doing other “housekeeping” chores

Pink Brain‚ Blue Brain In the article “Pink Brain‚ Blue Brain”‚ scientist conducted a case study where adults bought in their children that were aged around 11 months old. The purpose of the study was to explore the differences between boys and girls. During the study‚ it was determined that our brains are actually a work in progress‚ meaning that they change based on the experience that we have encountered; mostly starting at the early childhood. It was once thought of that boys were mostly physically

The introduction briefly talks about the hindbrain‚ its location‚ structure and highlights its main functions. It also talks about how the hindbrain is divided. The next topic is about Structure and Function. It first starts with the functions of the hind brain and then mentions each and every function of the brainstem‚ that it‚ the medulla‚ pons and the cerebellum. It also mentions the functions of the cranial nerves. The next section is on Injury and Disorder. Here it is mentioned‚ as a list‚

Something that surprised me the most in this radio interview about the teenage brain was how adolescents have a higher risk of substance addiction compared to adults (Jensen & Gross‚ 2015). Substances are more toxic and permanent on teenage brains than adult brains (Jensen & Gross‚ 2015). Originally‚ I thought that adults would get addicted faster because they often resort to caffeine to wake up‚ cigarettes to manage hassles‚ and other medications to relieve depression and stress (Berk‚ 2009).

What is Brain Chemistry? Brain chemistry or neurochemistry is the complex system which allows the brain to function with the use of chemicals known as neurotransmitters which move information around in the brain. Every person’s brain chemistry is slightly different‚ and a number of things can play a role in the levels of various neurotransmitters in the brain‚ and how those chemicals affect the brain’s function. It is believed that difference in brain chemistry may explain a variety of behavioral

Concept and magnitude of brain drain Migration of people as a phenomenon differs from country to country and from time to time. It is misleading to generalise about the possible effects of migration from LDCs. But even more fundamentally‚ one can argue that different studies are measuring differing things. All migrations cannot be justifiably brought within a single analytic umbrella‚ though it has been so done in the contemporary literature on the subject. Migration of HQM from LDCs may be due
