Thalamus

hippocampus. It is a large part that is embedded in the temporal lobe on both hemispheres. The hippocampus is vital for making new memories of events and information. Another part of the limbic system is the hypothalamus. It is located below the thalamus. Disregarding its small size, the hypothalamus contains more than 40 neural pathways. The hypothalamus is responsible for increasing and decreasing heart rate and blood pressure. It regulates things such as eating and drinking. The hypothalamus…

1. The pinna or auricle directs sound waves into the auditory canal. The eardrum vibrates according to frequency. Vibration transmitted to malleus then incus and then stapes of the middle ear. When the stapes vibrate, the membrane of the oval window is pushed in and out. This created the fluid pressure in the perilymph. Pressure waves enter the Scala vestibule then Scala tympani and then round window. This is where the walls become deformed in Scala vestibule and Scala tympani. Pressure…

One states that a fact is a reasoned idea, which contains multiple evidence for its existence. A theory is a dynamic, and official statement of guidelines upon a subject, and based off of ideas which explain the premise. The argument of “ facts are need to establish theories but theories are needed to make sense of facts” can be supported by the areas of knowledge in Social Sciences, Psychology, as well as in Natural Science, Biology. Both of these areas correlate in studying humans to the…

From an evolutionary standpoint, olfaction is one of the oldest senses. Aiding in our memory and also in the detection of hazards, the sense of smell became a necessity in the human struggle for survival. From the creation of synthetic fragrances to even the enhancing of our sense of taste, olfaction has even affected our culture. Our sense of smell has helped establish the human race into what it is today, but could it also be affecting us on a subconscious level? First we must understand…

Advanced, creative, and superior are characteristics that are synonymously associated with humans. Through the creativity and advancement of the human brain people have achieved the impossible. Humans have been able to travel in space, design machines that can break the sound barrier, and present hundreds of moving images on a screen. However, despite their advancements humans forget at times that they are just a type of animal like all the other creatures that inhabit the planet earth. In…

Through myriad articles, there is a known correlation between the use of a cellular device (whether hands-free or conventional use) and the increased rate of traffic accidents and driver distraction (Klauer, et al., 2014). These mobile phones, which are now capable of not only answering calls, but are also capable of playing games, text messaging, browsing the internet, etc... are now attainable for a vast number of individuals. According to the Cellular Telephone Industries Association (CTIA),…

suddenly become crazy or act unlike their usual selves. In these cases, their strange behavior was the result of a tumor in their brain. After Charles Whitman opened fire at the University of Texas, the medical examiner discovered a tumor in his thalamus, a region of the brain that regulates emotion. The damage to his brain caused emotional and social disturbances, and explains why Whitman, a seemingly normal man, did what he did. In a second example, a forty year old man named Alex one day…

that he is 19 years old and living in 1945. Jimmie’s longer term memory stopped dead in 1945. Gilles de la Tourette is a heightened sense that is explained in the book. This disease is “a brain disorder, centered in the ‘old brain’ involving the thalamus, hypothalamus, limbic system and the amygdala” (Butler-Bowdon). This disease is found to have “more than the usual amount of excitor transmitters in their brains, particularly the transmitter dopamine” (Butler-Bowdon). Sacks focuses on the…

The D.N.A. is a very complex topic that scientists still have a very few knowledge of so far. It is believed by most to be what defines human beings to be so special and unique compared to other individuals. If that is so, does Mother Nature also play a role in the terms of genetics in drug and alcohol abuse? Drug and alcohol abuse is the misuse and uncontrollable intake of drugs or alcohol, which may result to harmful effects to the body. If there is a relation between genetics and dug and…

How much of our life do we really have control over? This topic is covered in The Magic of the Unconscious: Automatic Brain which contemplates just how much humans are actually aware of and how much we genuinely decide. The video goes into an in-depth analysis of the automatic brain. It shows just how complicated the many processes the human brain goes through each day, in fact at every second. Humans are immensely unaware of how powerful and controlling the automatic brain is. This part of our…
