del-9-tetrahydrocannabinol (THC) and other related compounds. Which is Inhibitory neurons that plays a significant role in regulating neural signals it’s near the dopamine presynaptic cell possibly reducing the amount of dopamine that sent to the synapse by releasing the neurotransmitter gaba inhibitory and Gaba signals as it alters in response to local the brain activity. By adjusting the amount of dopamine released through stimulated dopamine neurons endocannabinoids which are…

There is fairly widespread agreement that adolescents take more risks at least partly because they have an immature frontal cortex, the frontal cortex is the area of the brain that takes a second look at something and reasons about a particular behavior. One interpretation of all these findings is that in teens, parts of the brain involved in keeping emotional, impulsive responses in check are still reaching maturity. In addition, Dr. Jay Giedd at the National Institute of Mental Health in…

I am currently pursuing a degree in Astronomy and Astrophysics at the Daytona Beach campus of Embry-Riddle Aeronautical University. One main issue that interests me and is an area I can focus my skill set towards is in the field of renewable energy. With the rising use of fossil fuel as an energy source, other means must be found to satisfy humanity’s need before our oil and gas reserves run out. An interesting alternative to conventional fossil fuel energy methods is that of nuclear power.…

The nerve cell knows when to release a neurotransmitter after an electrical signal is triggered. Once the electrical signal is triggered the nerve cell will secrete a chemical, the neurotransmitter, which will diffuse across the synapse. The synapse is a compact space between the target cell and the nerve cell. Hormonal Signaling Endocrine cells secrete hormones into the blood vessel, which then send them to target cells. For any cell signaling and response to happen, a specific cell must…

Neurons communicate over long distances using action potentials. Action potentials occur as a result of rapid changes in membrane permeability. Resting membrane potential of a cell is approximately -70 millivolts. Large anions trapped inside the cell, negatively charged proteins, as well as a higher concentration of positively charged ions outside than inside are some of the factors that contribute to the initial negative charge within the cell at resting value. Ion concentration gradients as…

Sleep is a universal constant between humans. Although it is so orthodox, if you really think about it, sleeping is actually quite odd. When we start our sleep cycle, the body becomes paralyzed and unconscious thus making us vulnerable. There must be a reason why organisms use sleep and why it isn't meaningless. Research in this area has been slow to take off; however, no one knows exactly the concepts behind sleep. There are several intriguing theories on sleep and why we need it. One of the…

for development, it is the actual experiences and relationships that children have that shape their brains. At the age of three, a child has approximately 1000 trillion brain connections or synapses, which upon later development are selectively pruned, by the time they have reached adolescence, brain synapses will only be around 500 trillion and continues at a stable level throughout adulthood. (Commonwealth of Australia,…

I have always been fascinated with the way the brain works. Before taking the course on human learning, I never put much thought into how a person learns, or even what learning is. Once someone takes the time to understand the brain and how it works, then that person can begin to understand the many psychological theories about learning. The study of psychology in itself is a hard enough topic for someone to wrap their head around. To fully understand the way learning is conducted one must…

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,…
