Introduction It seems to be the common rule that the younger we are when we try to learn something new, the better we are at acquiring the necessary skill. Our human performance is therefore a reflection of the neural circuitry that has been developed by early experiences. Yes, we are capable of learning new things when we are adults; however, it appears that those who have started younger, fare better. This is caused by the fact that we have certain critical or sensitive periods in our early…

In the article “The Impact of Malnutrition on Intelligence at 3 and 11 Years of Age: The Mediating Role of Temperament” the authors wanted to find out the effects of malnutrition on children’s intelligence and the role of temperament. In their hypothesis, they stated that “three aspects of malnutrition (stunting, wasting, and anemia) assessed at age 3 will be related to degradation of cognitive performance at ages 3 and 11 years, and also to an inhibited temperament at 3 years.” They tested…

matter hyperintensities on MRI and low fractional anisotropy (FA) on Diffusion Tensor Imaging (DTI) have found in patients with moderate to severe OSA as a consequence of repetitive ischemic-hypoxic insults to the brain,[63-67] resulting in abnormal myelin and axonal integrity over time.[68] Several longitudinal studies reported that C-SVD was associated with cognitive decline in patients with untreated moderate to severe OSA.[64, 69, 70] Therefore, when OSA causes damages to the deep and…

Only 1 in 100,000 people have to experience this scarce syndrome; Guillain Barre could possibly temporary have a serious affliction on the individual’s life, some of which we have heard of. Take Franklin D. Roosevelt for example, he suffered from Guillain Barre or also commonly known as “GBS” experienced a fight with this nerve damaging infection. GBS progressively starts to own a person’s life, being educated about this disease, the symptoms and effects, and the treatments will be beneficial.…

Alternative Imaging for MRI in MS MRI is a great tool for medical imaging and widely used for Multiple Sclerosis (MS), but it has some limitations in lacking specificity1. New emerging techniques such as transcranial magnetic stimulation (TMS) and optical coherence tomography (OCT) have the potential to address issues not resolved by current MRI techniques. TMS is a non-invasive technique used for monitoring the central nervous system (CNS) activity and response in a pain-tolerated manner. It…

The primary function of a neuron is to communicate information to other cells in electrical and chemical form. It’s important for everyone to know how neurons grow and develop. The main components of a neuron are the dendrites, the axon, the myelin sheath, the axon terminals, and the soma. The model of a neuron is very similar to the structure of a tree. Starting from the top, there are the dendrites. These are short fibers that extend from the soma. The job of a dendrite is to receive…

The difference between nature and nurture is that nature is the idea that behavior is effected by your chemical and gene make up while nurture is the idea that you are a blank slate and your behavior is distinguished by experiments. They both effect behavior is what was discovered. * Dualism is supported by cognitive psychologists such as George A. Miller and Sigmund Freud * Rene Descartes dealt with Monism vs. Dualism & Interactive Dualism * Monism is the belief that the mind…

For Healthy Brain: Desiccated Coconut makes your brain healthier and produces neurotransmitters which are known as the ‘Chemical Messengers’ as they communicate information in the human body. Consumption of dried coconut increases the production of Myelin in our brains which is good for the brain and nervous system. Therefore, the use of desiccated coconuts is beneficial to the health of the brain. 4.To Cure Alzheimer Problems: Researchers identified that consumption of coconut oil is very…

certain way or perform a certain action. In a neuron, it first has to have a certain amount of depolarizing ions for there to be an action potential. When that action potential is reached, charge can be sent through the axon (which is protected by the myelin shealth). As a charge goes through a neuron, vesicles that hold neurotransmitters (that are contained in the presynaptic terminal button) can be then released to the postsynaptic spine. After traveling across a small space that separates…

Cloning is done mostly so as to come up with cells and tissues that are self reconcilable and can be used for medical purposes to prevent diseases and even for transplant of organs. Cloning has raised a lot of issues in terms of ethics from the church and even in medical fields in regards to how safe it is and its potential to being abused. This article looks at the benefits and risks of cloning for spare part human organs and the prevention of predisposed diseases. Research shows that there…
