Neurons This is how I would explain the electro-chemical interaction between neurons to a friend. Imagine standing in a giant room with a large number of other people -- each of you are holding your arms out to either side of your body, like Leonardo Da Vinci's drawing of "Vitruvian Man." The giant room corresponds the brain and the nervous system, and you and the other people are each individual neurons. You

Each has its own skills associated with that specific areas (e.g. thinking is generally associated with the frontal cortex whilst vision with the occipital lobe; the frontal lobes are associated with motor control, speech, abstract thought, and sense of self, whilst the parietal lobes contain bodily sensations and the temporal lobes record hearing). Likewise each hemisphere has its specific expertise too with the analytical left containing speech, mathematical skills,

NEURONS AND NEUROTRANSMITTERS Neurons and NeurotransmittersNeurons, in basic terms, are cells (in particular nerve cells) responsible for the sending of messages across the body (Levin, Decker, and Butcher, 2012). They are considered to be the brain�s as well as nervous system�s fundamental units. To a large extent, they make it possible for a wide range of activities and functions to be performed including, but not limited to, walking, eating, talking,

Bacterial Toxins & Damage to Neurons Which bacterial toxins have negative impacts on the human body? This paper reviews those toxins and their effects on human functions. Clinical Diseases Professor F.H. Kayser explains that "Exotoxins" are pathogenic bacteria that are capable of producing a "variety of toxins that are either the only pathogenic factor" in the onset of diseases like diphtheria, tetanus and cholera, or if they aren't the only factor they are

As part of the experiment, another person entered the study area and expressed feelings of anger at the researcher for some time and at other times remained neutral. Later the researchers found that children who had witnessed the angry person were less likely to play with the toy compared to the children who had witnessed the neutral person. Also the researchers found that even the children who had seen

Its [mylelin insulation] growth enables a baby to gradually hold up its head, and its destruction by diseases such as multiple sclerosis causes severe impairment" (Chen 2009). Researchers have also found that both brain tumors and neurodegenerative diseases, such as Alzheimer's disease may be the result of problems with glia cells. Clearly, glia "are more than mere support cells that cater to the needs of neurons" and a "dynamic
