Fruit Fly Brain

“The Human Brain”, by myPerspectives, is an informative article that claims that the brain is a complex organ that is truly impressive. The brain is a key part of the central nervous system, that controls the entire body’s activities, to simple things such as breathing. These actions are fired through neurons, that quickly travel through the spinal cord. Surprisingly, the brain transmits these messages at an unimaginable rate, at 150 miles per hour, through 85 billion cells, called neurons. These neurons can form up to 10,000 synapses, or connections to each other. By itself, the brain can create billions of synapses, which change the structure of the brain every time new information is learned. However, there is still much that scientists

In the article titled, “Secrets of the Brain” published in the February 2014 issue of National Geographic, we learn that there have been many advances in understanding the inner workings of our brains. One of the leading scentists, Van Weeden, is working hard to understand the connections that occur within our heads.

Throughout this experiment a number of random and procedural errors were apparent; these errors could have affected the results of the experiment in a number of ways. One experimental error that occurred during the experiment was that some flies became stuck in the food source and died. The main cause of this was the fact that the fly vials were stood up (vertically) before the flies had fully recovered from the anaesthetic. This could be overcome in future experiments by ensuring that the vials are kept horizontal until all of the flies fully recover from the anaesthetic.

The parents are both homozygous. The homozygous dominant would represent the wild type. And the homozygous recessive would represent the other fly parent of a different strain. The F1 generation would consist of 100% Wild Type but they would all be heterozygous in carrying the recessive gene.

Do you support the findings of whole brain research? If not, what problems do you see?

It was the 17th century British scientist Thomas Willis who recognized that the custard like tissue of the brain was where our mental world existed. The brain is an electric organ. Now we know that instead of animal spirits, voltage spikes travel through it and out into the body’s nervous system.

After the BBC experiment many websites and doctors started examining the breakthrough study. The aforementioned website also states that “The results were startling. Individuals paced neurotically in their cells, and some reported visions of oysters, zebras and tiny cars. Psychological tests administered before and after the ordeal demonstrated significant declines in subjects’ intellectual faculties on the one hand, and increases in suggestibility on the other. (University, 2011)”

The results of human biomedical research conducted on non-human primates is not as accurate as it would be if these tests were performed on humans themselves. One reason for results not being as accurate is that even though non-human primates share “similarities with human physiological and behavioral characteristics.”(60) with this in consideration we must remember these similarities do not mean that non-human primates are the same as humans. Even though humans and primates DNS is “85% to 95%”(CITE) similar there is still 5% to 15% that is different. This biological difference is one of the factors that adds to the ability that “we cannot derive final and conclusive results from animal and non-human primate experimentation.” (Quigley, 656) If it is scientifically proven that no concrete results can be derived from testing on non-human primates then this research is close to meaningless.

But this isn't just about reading minds; it's also about bombarding them with messages or tweaking their chemistry. Transcranial magnetic stimulation — now used

This lab was a simulation of the capture and recapture and counting of birds. For example the West Nile Virus infected many birds and they would test the amount of birds with the virus, this is the way they would keep up on the spread of the virus. We tested the concept of the census and counting of all birds in a certain area. We used the beans which were marked and some werent.

Fruit flies with normal wings have a higher population and greatly outnumber the population of fruit flies with dichaete or vestigial wings.

of communication that sends information from cell to cell. These cells release a chemical which

At the end of our experiment, we were able to calculate the error percentage with the actual calculations. We were also able to compare the Punnett squares too. Some of the actual calculations were quite different than the expected, while others were spot on. One example is with normal wings, yellow body, our actual was two thousand two hundred and eighty-four flies and so was our expected. Whether the results were spot on or completely different we still had results to compare to the expected amount of each type of fly.

Instead of doing a test on animals, scientist can run a much more safe and accurate test using different methods. Kara Rogers, a Britannica’s life science editor states, “Study Cells put in
