Nerve Cells and Nerve Impulses

Lets talk about Nerve impulses. As we most of us know, axons are used to transfer informations, nerve impulses, from other neutrons, organs, or muscles. The are the super highway for these nerve impulses. These impulses do not always travel at a constant speed. Some could travel as slow as 2 mph and some could travel as fast as 250 mph, close to the top speed of a Bugatti veyron. It takes roughly about 70 to 80 milliseconds for the nerve impulses to travel and to register to our brains. So if we touch any part of our body, our forehead, shoulders or toes, we would feel it 80 milliseconds later. Does this mean that what ever we do, we would feel or know it 80 milliseconds later?

With this thought in mind, I aimlessly wondered around Youtube. I then came across a video by Vscause titled, You live in the past. The tittle itself got me asking some question, what do you mean I live in the past? That can't be possible. Out of curiosity, I decided to watch the video. Here's the video so you can watch it too:

This video is quite mind boggling. I know that there's is a lag time for nerve impulses to travel to our brains, but never have I thought of it on our perspective of time. I just think that this is very fascinating.

Intro to Physiological Psychology

One of the topics that was brought up on our assigned reading was the topic of  animal testing. I have encountered this topic before but I haven't given any thought of how I feel about animal testing.

I've spent hours contemplating my position in this argument. It's every easy to say that animal testing is unacceptable, because of how the animals were treated in the laboratories where the test were conducted, and its must be stop. But at the same time, a part of me is saying that animal testing is a good thing since almost all of the medical advancement we have today, from finding out the cause of many diseases to the perception medications that some of us take, were made possible through animal testing. I guess you can say that I am for animal testing but only for medical purposes. 

As we all know, animal testing does not just limit itself in the medical field but it has made its way through cosmetics. I believe testing cosmetics on animals is pretty pointless to us. It seems to me that these kind test are done so they could see how good or bad their product is and what  can they do to improve their product. 

This video by Lush, a cosmetics company, is a propaganda against the use of animal testing on cosmetic products. The video is graphic so "viewer discretion is advised."

Animal testing will always be one of those issues that everybody has their own point of view. What are your thoughts on animal testing?
