Mobile Brain / Body Imaging - 1650 Words

My topic is mobile brain/body imaging. As my presentation, mobile brain/body imaging(MoBI) is a general research approach that embraces a variety of hardware and software solutions like EEG to record and analyze brain dynamics in actively behaving participants, while traditional brain imaging approaches do not allow for any kind of movement. There are two type of lightweight and mobile sensors like electroencephalography (EEG) or near infrared spectroscopy(fNIRS) using in MoBI approach. While fNIRS lacks high temporal resolution that is desirable investigating fast cognitive process, EEG which provides necessary temporal resolution is preferred to be used in a MoBI approach. [1] What’s more, recent investigations using MoBI have demonstrated that equivalent dipole reconstruction of independent components(ICs) as decomposed by independent component analysis (ICA) allow for reconstructing the origin of EEG activity with reasonable spatial accuracy. Therefore, such a MoBI approac h will be considered as aspects of cognitive activity associated with the accomplishment of a task in the future study. First MoBI studies investigated participants walking and running on a treadmill and clearly demonstrated that brain activity can be analyzed under such conditions. However, walking is a highly symmetric recurrent behavior that does not include fast movements associated with jerk. Stereotyped movements like walking further allow for extracting templates of artifacts based onShow MoreRelatedInternet Usage Addiction1079 Words   |  4 Pagesinternet is also tied to some health concerns one of them being depression. Heavy use of the internet results in various mental problems on individuals. Studies have shown that over usage of the internet by teenagers disrupts the brains’ nerve wiring causing a level of brain damage normally seen in individuals who abuse heavy substances. Being constantly hooked on behavior, such as the internet can be physically damaging as addiction to alcohol and drugs, the scientists believe (Lin).

X-rays come from fast electrons that decelerate after striking something. Advantages of x-rays are they can be used to check if anyone has any broken bones in their body. Disadvantages are that x-rays can cause mutations in the DNA, they can cause cancer and they can cause cell damage by making blood cells have a higher amount of hydrogen peroxide. Ultraviolet Ultraviolet is found in sunlight and it can help stimulateRead MoreSoftware Components Of The Hardware Platform Available Essay1400 Words   |  6 Pagesreality and retail have collided spectacularly in recent years. The retail landscape is overcrowded and customers are becoming desensitized to traditional marketing methods. That’s where augmented reality comes in. As shoppers turn to a blend of online, mobile, and bricks-and-mortar shopping for their convenience, brands and retailers have to think of new and innovative ways in which they can capture customer attention. Augmented reality has the power to bring an image, product label or even shop windowRead MoreThe Parkinson s Disease Foundation1443 Words   |  6 Pagesmedications, treatments, and surgery are given to prolong and stabilize a person with the disease. Parkinson s is when the vital nerve cell called a neuron dies. This happens in the part of the brain; substantia nigra, the dying cells still provide dopamine which is a chemical that sends messages to the brain to control body movements and coordination. As the disease increases and gets more severe, the amount of dopamine produced decreases which is when a person typically relies on medications to help controlRead MoreComputers in the World of Healthcare1259 Words   |  6 Pagescomputer to view or send by email. The medical field uses different kind of input devices to ensure the best patient care. This means that information is inputted in to the computer by an input device. An x-ray sends individual particles through the body to be able to take a picture. This picture is then recorded on a computer or film to view. The x-ray uses a computer program the recreates the internal structure of the patient. A CT-scan also produces an image with the same computer program.

The nucleotide bases that make up DNA are complementarily transcribed into RNA, edited and altered, and translated into proteins. These proteins then function as building blocks for an organism’s body, or as construction workers to actually build and maintain the function of the body. Because human and chimpanzee genomes are more than 98.5% identical at loci that code for proteins, a U.S. research team theorized that it was not likely for the extreme differences between humans and chimpanzees
