Georg Friedrich Bernhard Riemann was a German mathematician who made huge contributions to the field of mathematics, and more specifically calculus. Riemann was born on September 17, 1826 in Breselenz, Germany. His father, Friedrich Bernhard Riemann, was a poor pastor, and his mother, Charlotte Ebell, died before her children had reached adulthood. Growing up, Riemann showed exceptional skill with mathematics, such as his abilities in calculation. In fact, in 1840, Riemann went to live with his…

My motivation to study machine perception is my long-term passion for mathematics, programming, and the human brain. Before knowing much about machine perception, my main motivation was to participate and securing the first prize in Bangladesh Mathematical Olympiad for three times. Following this achievement, I graduated in Electrical Engineering taking major classes on theoretical signal processing and accomplishing a bachelor thesis on the modeling of brain hemodynamics. This made me…

Techniques like MR spectroscopy, Diffusion Tensor Imaging (DTI), Perfusion Weighted Imaging (PWI), Susceptibility Weighted Imaging (SWI), Functional MRI, Positron Emission Tomography (PET) are utilized as per the requirement. For instance, a third grade Oligodendroma can be visualized accurately…

lean. During the single-leg squat test, she had a slight inward movement at her knees. Both tests showed that she has tight muscles in the lateral part of her legs. These tight muscle include: the soleus, lateral gastrocnemius, the adductor complex, tensor fascia latae, vastus lateralis, and the short head of the biceps femoris ((NASM), 2013). She also has weak muscles on the medial part of her legs. These underactive muscles include: Her medial gastrocnemius, medial hamstring complex, gracilis,…

Dark matter leaves astronomers and physicists baffled as to what it possibly could be. Scientists design experiments to attempt to figure out what it is, but no one truly knows what composes dark matter. Physicists are so interested in understanding dark matter because it accounts for the formation of the Universe, as observable through studying the distribution of gravity within galaxies (Carnegie). Original attempts at studying dark matter referred to dark matter as baryonic, which is a word…

associated with vascular depression[24, 53, 54] and cognitive impairment,[55-59] including episodic memory impairment.[60-62] OSA is an independent risk factor for C-SVD. White 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…

NEUROIMAGING AND COGNITION IN MS 1. Structural MRI Cognitive impairment in MS has been shown to correlate with different indices of brain pathology as revealed by MRI.  Lesions and atrophy: Studies have shown that global markers of impaired cognition have been linked to total hyper- and hypo-intense lesion volume (Rovaris et al., 1998; Lazeron et al., 2005; Sperling et al., 2001; Rao et al., 1989). This may be due to the lesions disrupting cortical-cortical connections (Lezak, Howieson&…

Neurodevelopment (CMIND) Authorship Consortium on 23 healthy, right-handed children, ranging from ages 7-9, calculated the relationship between reading comprehension (right hemisphere) and language comprehension (left hemisphere). With the use of Diffusion Tensor Imaging and fMRI, the researchers were able to measure brain activity during a Sentence Picture Matching task. The researchers found that around 10-15% of elementary school children showed poor comprehension skills despite their normal…

Introduction Recently, there has been a rising concern regarding concussions and contact sports. Rudd, Hodge, Finley, Lewis, and Wang (2016) state that the World Medical Association claims that boxing “produces an alarming incidence of chronic brain injury” (p. 1). In addition to the prevalence of concussion in boxing, Moriarity et al. state that “amateur boxers participating in a carefully supervised competition can have cognitive impairment suggestive of a concussive injury despite the…
