Olfactory bulb

On March 3, 1847 nobody knew that an amazing inventor was born; This inventor was Alexander Graham Bell. Alexander Graham Bell was a scottish-born scientists and inventor that was known best for inventing the first working telephone in the year of 1876. He later founded the Bell telephone Company just a short year later. Even though he is greatest known for his invention of the telephone he is also known for many other great inventions. People wonder how he became the inventor of the telephone,…

remarkable individuals. Edison is known for many of his inventions ranging from the phonograph to an industrialized electrical system; but I believe that Edison’s greatest invention is one that we still use in our daily lives, the incandescent light bulb. This incandescent lamp became extremely successful due to the advantages it had over its rivals. Before its invention, society was force to use inefficient and dangerous forms of lighting such as arc lights and gas lamps. Compared to its…

Events in the Olfactory System Olfaction is dependent on a large network of multiple primary and secondary processing centers connected in parallel and serial manners. Some of these centers are linked with non-olfactory regions. Olfactory receptor neurons project into the olfactory bulb which projects to the olfactory cortex. The olfactory cortex is a three layered cortex with several distinct sub-regions, the largest being the pyriform cortex. The other main components of the olfactory cortex…

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…

cortex. Furthermore, the CEA projects to visceral centers in the brainstem. Also, the extended cortical division of amygdala contains the cortical amygdalar nucleus (COA) - accessary olfactory bulb input as well as the rest of the COA, the nucleus of the lateral olfactory tract (NLOT), and the areas of main olfactory bulb input. Moreover, the lateral nucleus amygdala and basolateral nucleus amygdala form a ventromedial extension of the claustrum for large regions of the frontal…

of the olfactory framework. In spite of the fact that it had been built up that people and different warm blooded animals were fit for recognizing somewhere in the range of 10,000 unmistakable scents, the hidden systems of this procedure remained a mystery.Through the span of quite a long while, Buck revealed a vast collection of genes that are related to olfactory receptor cells. The cells, which are…

The olfactory nerve is longer than the olfactory bulb. Guanophores start appearing on the lower jaw with the opening of the gill chambers being wide. The distal half of the fingers on an outstretched forelimb extend beyond the base of the hindlimb. The anterior border of the adult…

Lledo et al, 2005). The mammalian olfactory system controls a plethora of functions such as homeostasis, emotions such as fear, anger, pleasure and anxiety, sexual and maternal functions as well as communal behaviours such as distinguishing between tribe or family and outsiders (Lledo et al, 2005). Rodents have a separate organ known as the vomeronasal organ to detect chemical compounds such as…

The special senses are hearing, equilibrium, vision, taste, and smell. Hearing is associated with the ear and how the sound waves travel through from external to internal ear. The external layer of the ear consists of the auricle, external acoustic meatus, and the tympanic membrane. Sound enters through the auricle, which carries the sound waves to the external acoustic meatus (i.e. ear canal). The external acoustic meatus in turn carries the sound waves to the tympanic membrane (i.e. eardrum).…

and sandalwood help the brain’s speed and accuracy in completing a puzzle. The sense of smell begins in the back of the nose where millions of sensory neurons lie on a tissue called the the olfactory epithelium. As soon as an odor molecule binds to a receptor, it sends an electrical signal the olfactory bulb, which is where the smell is identified. Then, the thalamus which is the key relation station for sensory information sends the smell information to the hippocampus and amygdala. The…
