Neuroscience Website

The link to the site

Today at this website I found. I learned about the West Nile Virus, and how the mosquito's actually get it from birds. I also learned a lot about your Eyes and about afterimages and illusions. I also learned how to find your blind spot. I also did the Stroop effect and learned how to do brain in sign language. I also learned the names of some phobias, and some of them I had, such as My opinion major Toxiphobia(fear of Poison), Arachnophobia(we all know is the fear of Spiders), Minor Entomophobia(insects, I don't fear them all though), Cancerophobia(fear of, you guessed it, Cancer), and Panthophobia(fear of disease). Chemicals with the Brain, like Caffeine is not bad for your brain, but cocaine can confuse it. I also did a game they had called Neuro-Jeopardy, I thought it was pretty good. I did Brain Response Time Experiments. I also did some Brain Facts that would make you go Hmmmmm. Looked at some kind of funny Brain Jokes. I learned about Yawning, yes yawning. The purpose of yawning is too stretch, not to warm up your blood or get rid of excess carbon dioxide and bring in more oxygen, although that is a good Theory. Another myth is that you have 2 brains, but its not true, your brain is just divided in a Left Hemisphere and Right Hemisphere. Its also a myth that you use 10% of your brain, that was a misquote of Albert Einstein. I learned how much your computer is like your brain. It learns, calculates, both uses electricity. They also can get damaged, a brain can get a disease and a computer can get a virus, they can learn, they can have a memory that grows and more. I learned an interesting thing about chocolate, it contains approx. 380 chemicals! No wonder its poisonous to dogs! I also added more stuff to my brain about Synesthesia. Also about yawning, its contagious! I learned about Rabies, which from the Latin words means "to rage". It is a virus. I learned about Lead. I was relieved that graphite is in pencils not lead. There used to be lead I think.

Synesthesia. A gift, and a curse.

Synesthesia is a condition of the brain which is harmless, that gives the senses a certain connection to each other. It allows stuff such as if you taste Spaghetti you could see Pink, even though Spaghetti is not pink. You could smell Licorice and hear an Oboe. You could feel a metal doorknob, and taste metal, vice versa. There are so many connections they cant be counted!

How Synethesia occurs
* After birth the neuronal wiring's in the brain are not yet specialized. They are overlapping each other. Until the forth month there is a process of pruning this connections. The failing of this process could lead to Synaesthesia. So this theory emphasizes that Synaesthesia is a result of too less neuronal inhibition. Inhibition enzymes could be involved. So basically, you can only get it from birth.

An overload could be if you go into a loud room, for example, your Synesthesia could make you very very uncomfortable! You could probably figure out why, You taste a lot of grilled cheese sandwich's listening to very loud music, or feel very smooth things while hear loud noises, etc.

Synesthesia is a very cool condition. The only harmful thing that it could possibly do is cause a small discomfort like I added above. Although, people could also have red skin, because of how you see them.
