Neocortex

In 1950, Alan Turing published his groundbreaking work “Computing Machinery and Intelligence,” which said that all digital computers, regardless of how they are put together, are equivalent in their computing abilities (442). This breakthrough in computer science has since fostered immense intellectual growth in artificial intelligence. For more than half a century, scientists have been working toward creating machines that are intelligent in the same way human beings are intelligent. Scholars…

to it produces insomnia, an inability to sleep. Although REM sleep and wakefulness have many similarities, many differences occur, such as the role of the thalamus. The thalamus has been considered the gateway between the sensory organs and the neocortex, a relay station while the body is awake and blockade during sleep. Although, some may think REM and non-REM are the main focuses of sleep, it is not. However, we know that the thalamus plays a key role in organizing behaviors during the…

control what we’re feeling? Let’s start with our memories. There are 3 types of memories that we have; and they are all stored in different parts of the brain. Explicit memories are stored in 3 very important parts of the brain: the hippocampus, the neocortex, and the amygdala. Their jobs are to help you remember events that happened to you (episodic), as well as general facts and information. Our second kind of memories are called implicit memories. They rely on the basal ganglia and the…

Cognitive and Biological Interaction FQ: to what extent does cognitive and biological interact with emotions? The cognitive level of analysis and biological factor of the two when dealing with a specific component of the brain known as emotion. What the cognitive level of analysis aims to study the inner processes of the mind and how cognitive process guides behavior. Within the level of analysis, emotion has been investigated in terms of the biological and cognitive influences. A biological…

of the hippocampal dentate gyrus and the subependymal zone [SEZ, also subventricular zone] adjacent to the lateral ventricles [1, 2]. Lower levels of neurogenesis have been reported in other regions of the rodent and primate brain, including the neocortex [3, 4], amygdala [5] and substantia nigra [6], but this has been difficult to replicate consistently other than in the diseased brain [7]. Other studies provided compelling evidence that precursor…

I've been finding myself lying awake more and more recently, tossing and turning and tangling the blankets, unable to sleep. Getting into staring contests with the shadows pooled like ink in the edges of my room. Now, insomnia is a problem a lot of folks have, and I’m certainly no stranger to it. Stress, problems- kids, bills, the corrosive apathy of suburbia- they fester and rot in the recesses of my thoughts, and the sleeplessness lets itself in through the holes all that shit eats away. Just…

memories intact, which further supports the idea that the medial temporal lobe plays no role in the retention of remote memory (Bayley et al., 2005). However damage to the prefrontal cortex can lead to remote memory impairment, which is why the neocortex is supposedly responsible for remote memory (Wiltgen et al., 2004). Are remote memories truly independent from the hippocampus and the medial temporal…

The difference in the meaning of AI and AGI come from the old definition and expectations of what AI was compared to the one we know today. There was a proposal made to research AI at Dartmouth College in 1955 which stated: The study is to proceed on the conjecture that every aspect of learning or any other feature of intelligence can in principle be so precisely described that a machine can be made to simulate it. (McCarthy, Minsky, Rochester & Shannon, 1955, p. 13) This idea of AI is the…

A. Please use the following probes to reflect on and share with us what you have been learning in class so far: • You have viewed four of the seven presentations in the Seven Slide Series over the last two weeks. What were some of your key takeaways? Are they concepts or constructs that you struggle to understand? Some of my key takeaways of the seven slide series presentation has been in how miraculously our brain is made and how its function. Each part of the brain plays an…

Jimmie G’s problem is that he has anterograde explicit declarative amnesia. He cannot make any new memories, meaning his explicit memory, or his ability to consciously recollect memories, is only good for memories made before his injury presumably. His declarative memory is also damaged, as evidenced by his inability to remember the correct year and his inability to recognize that he is no longer 19. He can still access his implicit memory as evidenced by the fact that he remembers the routine…
