Neuroanatomy

3. A. Cranial nerve involvement can be broken down into two portions. The anterior 2/3 of the tongue are innervated by the Chorda Tympani branch of the Facial nerve which is carried by the lingual nerve which branches off the mandibular branch of the Trigeminal nerve. Sensory component of the anterior 2/3 is maintained by the lingual nerve. The posterior 1/3 of the tongue is innervated by the glossopharyngeal nerve which supplies both sensory and taste. B. The human tongue contains multiple…

Our sensorimotor has many parts to function and manipulate what we want our body part to do. We simply must think and react to what are next move and in rapid millisecond either our hand or leg moves. As this occurs, our primary somatosensory cortex that’s located in our central sulcus has a full chart of information lined up for our function to travel all the way to our spinal cord and make a movement. As Agnosia damages the path of any function of either of the temporal lobe or cerebellum, it…

In modern times there is almost no way to avoid the internet. With all of the technology constantly surrounding humanity it is a wonder that human interaction still exists. With technology being such a massive factor in everyday life it must have effects on the brain. UCLA scientists have found that key centers of the brain that control decision- making and complex reasoning are triggered while using technology, the results suggest that web search activity may help stimulate and possibly improve…

What exactly is something that would be considered as a “brain rule”? These rules include things, which scientists know for certain about how the human brain operates. The human brain is a fundamental, physical system that requires sleep, exercise and proper nutrition in order to function optimally. The body and the mind aren’t separate things; the human brain is a physical system which has needs that are physical. John Medina goes into detail in his book, “Brain Rules” about how an individual…

According to Dr.Gottfried Schlaug, associate professor of neurology and director of the Music and Neuroimaging Laboratory at Beth Israel Deaconess Medical Center and Harvard Medical School, “Neuroplasticity is the term for the brain’s ability to pave new pathways around damaged areas,”(Mossie). Due to this incredible ability that the brain has, Congresswoman Gabby Giffords relearned to talk within ten months of having a bullet wound to the head. Giffords suffered from aphasia- the inability to…

The brain is the most complex part of the human body. It is also the most powerful organ of the human body, although it only weighs approximately three pounds (Alzheimer’s Association, 2012). The brain is responsible for all thought and movement that your body produces. The complexity of the brain allows humans to interact with their environment and communicate successfully with others. The brain is not just one huge organ, it has numerous small divisions that enable humans to thrive and survive…

The 1983 study by Zihl, Von Cramon and Mai investigates motion blindness, or akinetopsia. The patient suffering with this disorder had a very limited perception of visual motion, motion in depth, apparent motion and did not see motion after effects. Brain damage, specifically bilateral, posterior brain damage, can sometimes result in disturbed perception of color and, as in the case of L.M., motion. More specifically, the area that was damaged was assumed to be the posterior part of the middle…

It is an important and interesting question on how feelings and emotions emerge inside our human bodies. It is a known and general fact that emotions come from the brain, yet it is also evident that specific areas of brain are responsible for productions of feelings. In order to better understand the production mechanism, it is vital to get deeper into the brain’s emotional map and examine particular areas. One of these specialized areas of central interest is the amygdala that is responsible…

Carl Zimmer, the author of this article, is a well-known science journalist and author. Within this article, Zimmer discusses what he has learned about the human brain, and in this paper, I summarize the main ideas and points that are brought up, while adding my own comments on its contents. The brain is known for being the most mysterious organ. Our current technology and methods of observation and experimentation are not advanced enough to unveil all that there is to know about it. Most of…
