MCI is considered the borderline between normal cognitive aging and very early dementia []. The historical evolution of the MCI concept has recently reviewed by Petersen [], including the more recent formulation by the Diagnostic Statistical Manual-5 (DSM-5) []. In general, the MCI syndrome is characterized by a cognitive deficit greater than expected for the individual’ age and educational level, but not enough to significantly interfere with the functioning of his daily life. According to…

Frank Guenther talked about his research on the DIVA (Directions Into Velocities of Articulators) model. He explained that it is a neural network model, which deals with the creation of speech and the attainment of speech motor skills. Using computers he explained the model is able to regulate the actions of a vocal tract to create speech sounds. Guenther revealed that the DIVA model’s neural mappings are adjusted in a “babbling phase.” In this instance audio feedback from speech sounds is…

As I take you through the path of light I will be explaining what each structure is responsible for and how it handles light. As I get to the path light takes as it enters our eyes I will point out four mechanisms that have to function in order for us to see. Each of our eyeballs have six muscles that attach them to our skull. Four of these muscles pull straight and are called rectus muscles. Two of these muscles pull on an angle and are called oblique muscles. The first mechanism is the…

Everyone in this world faces adversity at some point in their life. Everyone is not, however, born with a genetic condition that has the odds stacked against them from the very beginning. Hutchinson-Gilford Progeria Syndrome (HGPS) is a rare form of genetic mutation that shows some aspects of physiological aging from a very young age. Symptoms become more prominent as a carrier of the disease ages. HGPS is of interest to me, because this is a disorder that resembles accelerated aging, and if we…

We hypothesized that there are common gene pathways responsible for the schizophrenia–type 2 diabetes mellitus association in drug-naive subjects. In particular, wepropose that the insulin growth factor 2 m-RNA binding protein 2 (IGF2BP2) genetic variants rs4402960 and rs1470579 .associates and replicated in type 2 diabetes mellitus Egyptians (14,15) gene pathways maycontribute to both type 2 diabetes mellitus and schizophrenia Through this exploration , we tried to link thepathogenetic…

be asking is was it worth it? Varying degrees of mountain sickness can affect a climber. They range from just headaches as a result of acute mountain sickness to death from High Altitude Cerebral Edema (HACE). High altitude climbing can also kill brain cells, which can impact a person later in life. High-altitude climbing is very dangerous because of the neurological toll it takes on the body. High altitude climbing is very dangerous because of HACE. HACE, also known as High-altitude cerebral…

the nervous system. Neurons communicate through synapses. The nervous system transmits all messages to the brain. The messaging process moves in one direction to the cell body, where the cell body transmits an electrical pulse to the neurotransmitter this creates an impulse. 2. Throughout the normal day you use multiple parts of your brain. An activity that uses more than ten parts of your brain at once is if you hold your hand over a flame. Your Frontal Lobes Lie just behind the forehead;…

This muscle group is used in almost everything a person does. It is a huge and important part of all of the functions of a human. It can be strengthened in many different ways depending on which part, if any, you would like to focus on. The Abdominal muscles do a lot for the body to keep it functioning. They assist in breathing and protecting the important organs within the body. They assist in bodily functions such as urinating, childbirth, singing, vomiting and much more. They also assist in…

have the ability to train their bodies to require less sleep, it is impossible. The body needs sleep to regenerate certain parts of the body, especially the brain. After periods of time with little to know sleep one will know immediate side-effects of the brain not being able to restore and repair it’s own neurons (Lancaster, 2008).The brain is one of the most complex and least understood things in the world and without sleep there can be severe damage to this. Cognitive ability and behavior,…

Alzheimer’s disease affects millions of people annually in the United States for no known reason. Alzheimer’s is a very complicated disease that affects mostly elderly people. As a repercussion, my objective is to become a neurosurgeon and help all those persons that suffer from this disease and maybe even find a cure to this extremely bad disease. When I see a person with Alzheimer’s I think about how their families are feeling about having a loved one to forget them as their family. My…
