Gender affects the human race in many different ways. It can be a separating barrier between people. There are stereotypes, such as both genders being unable to communicate effectively, females being moody, and males having no emotion whatsoever, that are only based on what the human race believes as a society. They might also include things like determining what one gender might be able to do better than the other. This brings forth the idea of whether one brain might be better than the other.…

's made up of two separate systems, the brain, and spinal cord. During prenatal growth, the nervous system experiences many changes to gain its compound structure. The events of this early development include the growing of billions of neurons, axons, and the formation of thousands of synapses. The cells in the nervous system are a special type and continue to grow during the organisms life. There are approximately 100 billion cells in the nervous system.…

Mojave Toxin in the Mojave Rattlesnake Neurotoxins are an often studied, naturally occurring set of chemicals with vast potential toward a variety of applications. These toxins are produced by countless different species of animals: amphibians, insects, arachnids, and even birds, just to name a few. Neurotoxins, a specific class of toxins, act by impairing or artificially enhancing neurotransmission at the pre-synaptic or post-synaptic level (Camp & Gilbert, 2014, para. 1-5). Neurotoxins…

This is due to the development of a set of specific neurons in each segment of the spinal cord (Brustein et al., 2003). In spontaneous tail coiling, each segment of the spinal cord is innervated by three primary motorneurons and they are known by their longitudinal position (Westerfield et al., 1986). The…

development known as “brain spurt”. • Normally, 70% of neurons will undergo apoptosis during brain development. Gamma aminobutyric acid (GABA) and glutamate receptor modulation may be involved in apoptotic pathway signaling. Anesthetic drugs exert their actions through these receptors, among many others, to produce loss of consciousness. • Delaying non-elective surgical procedures might put children at risk of disease progression,…

There are many causes of dementia and according to Janssen Pharmaceutica N.V., “There are some causes of dementia that are treatable which are head injuries, brain tumors, infections (such as meningitis, HIV/AIDS, or syphilis), simple and normal pressure hydrocephalus (i.e. when the fluid in which the brain floats is collecting outside or in the cavities of the brain, compressing it from outside), hormone disorders (i.e. that is, disorders of hormone-secreting and hormone-regulating organs such…

Part 3: Alzheimer’s Disease: A Doctors Secret Have you ever thought about how you will die, or what diseases you will get diagnosed with in you older age? Alzheimer’s disease is a “forgotten" thing in the younger generations, but its more present than we think. Many people 65 years and older have the disease without even knowing it until incidents like backing up out of the garage with the door still down, or falling asleep at the wheel, happen and they become utterly confused. So, is it…

An average person can remember things that happen in their lives whether it be for a short time, or a long time. There are many factors involving the memory of the brain such as sleep. The human brain is a unique and amazing place where one can store things about their life. Some would say, that the human memory is like a huge library of moments stored throughout our brains. In my opinion, this is a great process is that if we are experiencing something new in our life, we can go and look up a…

The choices I make now as a teenager and not nearly as important as those I will make as an adult. WRONG !!! The choices you make as a teenager greatly influence your ability to choose in your future. Your first choice is to decide which element in your brain will make that choice, emotion or your Intellect. Apparently for teenagers this is not an easy thing to do because, guess what, – our Brains are still developing – we do not yet have the brain capacity to easily make a reasoned choice.…

filled with undiscovered mysterious. The brain is composed of several different parts, each with its own job to carry out through the use of nerve cells. These nerve cells, or neurons, are abundant in the brain, creating over a thousand trillion connections among the hundred billion cells found within the brain. The neurons receive, process and transmit information from all parts of the body, controlling various aspects of the…
