Concussions are dangerous. Recently, some light has been shed on one of the newest yet most pressing issues of the most recent years. Concussions, a potentially fatal outcome from high impact collisions in aggressive sports. At a professional level, competitors are at an all time high in their athletic ability. Although there are much worse and life threatening injuries in sports, concussions are a common injury that can happen multiple times. With these types of forces and pressures on the head…

motivated behaviours such as Fleeing, Feeding, Fighting and Sexual Behaviour. It is also the centre of emotional responses. When the auditory senses experience any type of Music, Dopamine is synthesized out of amino acids, which transmit signals from one neuron to another through the circuits of the Brain. Dopamine is a hormone that gives a feeling of ecstasy during sexual intercourse, administration of certain drugs and breast feeding. According to McGill research (January, 2013), during the…

A human’s cognitive ability is unlike any other animal on the earth. Compared to other animals, the human brain possesses more neurons and synapses, tallying eighty-six billion and one hundred fifty trillion respectively. The wiring of the brain and its connections are responsible for human’s superior cognition. Thus, the reason neuroscientists pursue research of neural connections is obvious; neural connections are the fundamental basis of individual expression. Many famous neuroscientists,…

1. There is an increasing amount of elderly rising in today’s society. According to the U.S census bureau, and the 2010 census taken, the elderly percentage in America is steadily on the rise, due to the baby boomers (Ortman, Velkoff, & Hogan, 2014). In 2010, the elderly population made up approximately 13% of the entire U.S population, in one decade, the number of adults 65 and older, increased by six million people (Werner, 2011). According to this census, a group of analysts were able to…

head impact, the brain bashes and shakes around inside the skull. “Shearing forces stretch the membranes of the nerve fibers (axons) that connect the nerve cells (neurons) and, through a process that is not fully understood, trigger an energy crisis: Blood flow, which delivers glucose, is restricted at precisely the same time as the neurons’ demand for energy spikes.”(Taylor 77) Our brain in return shuts down areas on the brain which can last for long periods of time. With these hits, the brain…

Stop reading if this doesn’t fit. Have you ever felt like you wake up, get ready, maybe get the kids ready, head off to work or school, take the old same route to work every day, get off work, go to the gym, go cook dinner, watch some TV, get ready for bed, then go to bed and do that same day all over again. If this sounds pretty familiar to you; then it might be wise to go back and reread the mindless autopilot rerun of a life that you may be living. We usually don’t open our eyes to see what…

functioning normally Tau helps stabilize and support certain structures within the brain cell, but when the brain suffers a traumatic hit the proteins start to bend and clump furthermore, The build-up of these clumped proteins is what starts to kill the neurons and eventually the cell. The protein is then circulated throughout the brain, and this leads to the deaths of other cells. Currently, doctors can only diagnose CTE is after the player has died, that is because CTE needs to be diagnosed by…

When using music as a main means of communication and carrier of information it is important to understand how it affects the listeners. Exploring how the human brain processes that information gives interesting insights and valuable intelligence on how the listeners might be affected by the music they listen to. This type of research often gives information which even the listeners themselves might not be aware of. A researcher from the University of Montreal, Robert Sartori (2015), interviewed…

produced by earlier spikes. In depressing synapses, successive action potentials result in smaller and smaller postsynaptic responses. The reduction in postsynaptic responses could be due to smaller amount of neurotransmitter release by the presynaptic neuron. Depressing synapses are characterized by high starting release probability. Thus, there are large amounts of neurotransmitter release at beginning of stimulus train. However, this large amount of release depletes the number of vesicles…

A lot of what makes us up as people consists of neurons. Neurons are responsible for our bodies “communication system.” So much happens within our bodies at such a minuscule amount of time, and learning about the process made me realize how much needs to happen for me to feel a 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…
