Olfactory system

are just blocking any type of stimuli from the olfactory system. We can rule out this possibility by conducting a follow up experiment that would go something like this. With the optogentics activaitng this circuit of neurons the rats would be located in a maze with cheese somewhere to see if they can locate the source of the smell, in this case the cheese. If they can locate the cheese in a direct path then it means the inputs form the olfactory system are not blocked. If they stuble around the…

The purpose of this paper is to summarize, assess, and synthesize eleven chapters across two primary texts listed as the required reading for the second week of POS 543. First, I’ll identify some of the central themes discussed across the readings. Second, I will assess the strengths and weaknesses of the various contributions to the literature on organizational theory relative to the major schools of thought. The required reading for week two offered a glimpse of the classic theories…

They explain how the activity system define a group of people who share a common goal or motive. I completely agree on how an activity system allow certain communities are structurally connected. This is a great way to help you understand community relationships. Activity system is a good system because it “sees all aspects of activity as shaped over time by people’s social interactions with each other and the tools they use” (1). Everyone is in an activity system even if you don’t realize it.…

How Shake Shingle Metal Roofing Compares To Wood Shakes If you love the look of a wood shake roof but hate the thought of all the maintenance a wood roof needs, then you should consider getting a shake shingle metal roof instead. You'll have the look you like, but none of the upkeep required for real wood. Here's how the two types of roofing compare. Appearance You may imagine metal roofing to be in long sheets like you see on barns, but it actually comes in different forms. The metal can be…

All five of our different senses are important to have for a variety of reasons. They allow us to see, to feel, to hear, to smell, and to taste. There are also a lot of different parts of the body that allow us to experience these senses. If I had to choose which sense to lose though, I would choose to lose my sense of taste. One of our five senses is taste. The primary function of taste is to have us evaluate what we are eating. There are a few different areas that give us the ability to…

another, smells can have different meaning to different people. This article looks at Aromatherapy and how it allows us to capture the olfactory power of plants for healing. Aromatherapy was used hundreds of years ago, but never became common. The article also goes on to talk about how this Aromatherapy is working with our olfactory receptors and the limbic system itself to bring about emotions…

Fundamentals of a Roof Warranty Learn the basics of roof warranties and what homeowners should know before they buy. Roofing contractors and roofing material manufacturers both offer a variety of warranties designed to protect their customers from incurring excessive costs in the event of roof damage. However, it is essential for homeowners to understand a few basics about warranties, including what they are and are not, why reading the fine print is important, and how a warranty can benefit…

The Effects of Mefloquine (an antimalarial pill) on Mice Cognitive and Deficits in Olfactory Bulb. Mena Mekail Introduction to Scientific Research December 8, 2015 Introduction Worldwide air travel has seen a great increase in recent years, in fact it is projected that 1.45 billion people are expected to travel by air in 2016 (Huang and Tatem 2013). The increase of travel rate from malaria free and endemic countries has led to the increase of antimalarial drug resistance consumption…

in behavior over other others. The power of the study above and in this proposal lies in the use of a small model organism (Drosophila melanogaster) with a well-defined behavioral assay (aversive olfactory long-term memory (LTM)) and identified neural circuitry underlying this behavior (olfactory pathway-see Fig. 1A). Using the fruit fly circumvents the complexity comprising the mammalian brain and the distributed nature of behavioral circuits. Drosophila melanogaster (fruit flies) are ideal…

The effects of gene mutation on Olfactory Sensory Neurons in Caenorhabditis Elegans Amira Brown University of California, Santa Barbara Abstract This experiment examines the effects of distinct odorants on chemotaxis behavior of the nematode worm, Caenorhabditis elegans (C. Elegans). Nematode worms are appropriate for sensory physiology studies because its neuronal wiring is similar to that of humans. We focused on the role of three sensory neurons in the nose of the…
