Neocortex

He argues that there is a correlation between neocortex size and group size (Figure 1) and that when a size of a social group increases, the number of different relationships in the group may increase by orders of magnitude and when living in large groups, selection favored greater intelligence.

Sleep Balance: Does it really matter? Tom, a young adult, is in the current processes of transitioning from high school to college and as doing so feels stressed, as many thoughts rush through his head.

“As illustrated in in the case Cruzan v. Missouri, implementing assisted suicide would give the terminally ill and suffering patients the chance to die with dignity.” The cases involving death have always been controversial. As the life expectancy began increasing and people began dying in hospitals, the controversy over right to die and assisted suicide came into place. This is when Cruzan v. Director, Missouri Department of Health 1990 came into limelight and became a hot topic for the next…

Episodic memory is the process of recalling personally experienced past events. The efficiency of this process is adversely affected by age. In a sense, this may explain the level of emotional distress that the aged and their kin and all others feel at the onset of failing episodic memory Riding a bike, thinking of the trip you took when you were 10, and where to put the ice cream all have something in common(Dritschel & others, 2011; Wang, 2009).They are all are part of memory. Even though they…

Burton 1 The human brain is such a complex and beautiful organ of the body but yet is underappreciated. Many individuals of the human race fail to appreciate the importance of the brain, but that is just how their brain works! Ironic to think, but yet it is just as sad. Since the existence of mankind the human brain has constantly been evolving, growing stronger into the intricate, sophisticated organs of the present. By natural selection, certain people have a brain that is more developed than…

Study of the brain is significant in gaining insights on its structural and functional design and mechanisms which help explain the cause of various existing neurological and psychiatric diseases (Kotter, 2001). Consequently, the histological study of the nervous system and its components which underlies the understanding of the brain forms the basis and foundation of neuroscientific research (Annese, 2012). Important components of the nervous system include the spinal cord which consists of…

Never be afraid to talk to anyone. A lesson that I have been taught over several occasions and experiences since I started college, and which I will carry for the rest of my life. The first time was during the speech of the founder of the Millennium Campus Network, Sam Vaghar. He was telling his story at the Millennium Campus Conference in October 2013, about how he changed from a very shy and extremely isolated and introverted high school kid, to an ambitious, very well spoken young man who was…

The mammalian order Cetacea is composed of two parvorders, the Odontoceti (toothed whales) and the Mysticeti (baleen whales). They compromise of over 80 known living species of whales, dolphins and porpoises (Reiss & Marino, 2001; Simmonds, 2006). The compelling sets of characteristics they have acquired over their 55-60-million-year evolution including echolocation ability and complex social organisation (Hof, Chanis, & Marino, 2005) have created great belief that this order contains some of…

given is the relative of the size of the dolphin brain when compared to their bodies. They are shown to have a larger brain pound to pound when compared to certain primates. From scans of their brain the process from the different parts of their neocortex both visually and auditory level. Their reactions due to this are shown to be based on emotional and thought out response, to the events that…

Second brain change is neurofibrillary tangles in the cortex which causes the microtubules to disintegrate and collapse the neuron’s transport system. These brain changes lead to a loss or degeneration of neurons and synapses, especially within the neocortex and hippocampus. Reduction in serotonin receptors, serotonin uptake into platelets, production of acetylcholine in the areas of the brain in which plaques and tangles are found, acetylcholinesterase, and choline acetyl-transferase are also…
