Neuron

“The Universe is constructed of fundamental forces or fields, resembling an invisible nervous system, which stretches throughout space and is continuously vibrating, becoming and transforming trillions of times per second.” The neronons in our brain are constantly firing. The brain starts developing very early in life, about 21 days after conception. In many ways our developmental process is a lifelong project. This is because the same events that effect our brain during development are also…

CTE Crisis Today, people begin to question sports regulations due to a massive discovery of Chronic Traumatic Encephalopathy and Amyotrophic Lateral Sclerosis being found in the majority of athletes. As a whole, people are not seeing the true effects of athletes are struggling through. When one football game is over, fans continue into the next week and expect the same CTE-ridden athletes to endanger their life. However, this has been a national crisis we all have been blinded to for years.…

After the virus is transferred into a new host it enters the unmyelinated axon terminals. The infection then spreads through a chain of neurons that are connected by synaptic junctions. After uptake into peripheral nerves, rabies virus is transported to the CNS through retrograde axoplasmic flow (Concepts in the Pathogenesis of Rabies, 2014). After infection of the brain, the virus spreads…

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…

the nervous system are Nervous Tissue, Brain, Spinal Cord, Nerves, Sense Organs, and the Cerebrospinal Fluid. The nervous tissue is the main tissue of the central and peripheral nervous system. This tissue conducts nerve impulses and is composed of neurons. The brain sends messages to the spinal cord the peripheral nerves all over the body that serve to control organs and muscles. The spinal cord is a long…

Amnesia or amnesic syndrome, is a shortage in memory caused by damage in the brain. The person with amnesia won’t be able to remember certain things. The extent of the damage determines whether the memory is fully or partially lost. Though having no sense of who you are is a common plot device in movies and television, real-life amnesia generally doesn't cause a loss of self-identity. Instead, people with amnesia are usually aware and know who they are, but may have trouble learning new…

Visualize a disease that leaves its victims powerless but are completely aware of everything that is in sight and the state the body is in. With every intention to move, the victim has no control over the body’s muscles, for not a single finger is lifted nor a smile displayed. Such a disease does exist and has affected many lives worldwide. This awful illness is named ALS, Amyotrophic Lateral Sclerosis, a progressive neurodegenerative disease. With many diseases in the world, countless terrible…

This would mean that our memory and other cognitive functions would get irreversibly worse once we reached the legal drinking age. Thankfully, in the last few years, science has discovered that the human brain is more than capable of making new neurons well into old age. No matter how old you are, you’re never too old to rewire your brain…

Alzheimer’s disease is a form of dementia characterized by progressive, irreversible deterioration of general intellectual functioning. Alzheimer’s disease accounts for almost 80% of dementia diagnosis, and occurs in middle or late life. Statistically, it shows that it affects more women than men. Patients with Alzheimer’s disease die an average 4-6 years after diagnosis, however, the disease duration varies from 3-20 years. (LeMone, 2015) Scientist estimate that more than 5.3 million people…

are on the surface of the earthworm, if the temperature isn’t ideal for the earthworm then the action potentials won’t fire fast enough to get away from prey under those circumstances. The cooling effects placed on the earthworm effects the medial neuron which slows all action potentials coming and going. The other part of this experiment showed that when stimulus strength and durations of the action potentials are changed to higher frequencies the less time the cell has get out the the absolute…
