much of his motor ability but has lost some of his sensory function. What factors are involved that affect the regeneration of Brett’s neurons and neuron function? Clinical answer: For regeneration of neurons (getting sensory feeling back)‚ his type of injury involves the PNS neurons that were involved‚ rather than CNS neurons‚ so the chances of his neurons regenerating increase. Nerve generation depends on location of the injury‚ inflammatory responses‚ and the process of scarring. When

When an individual learns to walk‚ they retain the information in the memory. The learning process is something that happens every day. As human beings we are programmed to learn life lessons‚ and retain them in our memory. The memory keeps pictures‚ smells‚ experiences‚ and tastes for us to

brains continue to generate new neurons well past when was originally thought. This process is called neurogenesis‚ and until recently‚ was seen as a development only occurring in embryonic and perinatal stages in mammals. Luckily‚ this continues throughout life‚ and is beneficial to college students in multiple ways! Similar to progenitor cells in the developing brain‚ the adult brain contains a small number of stem cells that are able to divide and produce neurons. Through research conducted involving

It contains motor neurons that affect the axial muscles. The cell bodies of the alpha motor neurons are located here. A motor impulse from the motor centre in the brain is carried down to the motor cell in the spinal cord by an efferent fibre. POSTERIOR HORNS – The posterior horns of the spinal cord

underlying spatial behaviour could therefore help to understand such cognitive decline. An important contribution to this endeavour was the discovery of spatially modulated place and grid cells (Kiehn & Forssberg‚ 2014). Hippocampal place cells are neurons that fire whenever an animal is located in a particular region in the environment (Moser & Moser‚ 2008). These place cells remain to fire in a novel environment‚

Alzheimer’s disease is characterized as a type of dementia that causes problems with memory‚ thinking‚ and behavior. It is irreversible and it slowly destroys memory and thinking skills and‚ eventually‚ the ability to perform simple tasks. Unfortunately‚ Alzheimer’s is the sixth leading cause of death in the United States and over five million Americans are currently living with Alzheimer’s. There are many symptoms within each category of Alzheimer’s. In mild Alzheimer’s disease‚ where Alzheimer’s

if you’re learning a new skill you constantly have to think about it because you’re not used to it. Doing this can make you think and process information fast by strengthening your synapses. Thoughts are electrical impulses that travel from neuron to neuron through a synapse. It’s basically just transmits information‚ so the stronger the synapse the easier the brain and can transmit thought. I find it no surprise that nicotine improves a person’s focus. It is a mild stimulant which increases dopamine
