Cerebral cortex

ABSTRACT When brain scientist talk about plasticity, they refer to the molding of organs circuit by new experiences building new writing patterns, pruning others. Brain plasticity or neural adaptation or neuro-plasticity is the ability of the CNS to change & adapt in response to environmental cues, experience, behaviour, injury or disease. Neuroplasticity is assumed to be one of the essential characteristics of the nervous tissue which may be manifested comparatively rapidly and result in…

Analysis of “My Stroke of Insight” The Ted talk “My Stroke of Insight” given by a Neuroanatomist, Jill Bolte Taylor, is about how humans have a left hemisphere and a right hemisphere and how humans have different perceptions of themselves because of it. In the right hemisphere people tend to think that they are “energy-beings connected to one another through the consciousness of our right hemispheres as one human family.” People who tend to think with their left hemisphere are responsible for…

The human brain can be modelled as a matrix of dots. Each dot's color can be flipped to opposite colors. When a baby is born, it's brain matrix consists of a very low m x n dots. As the baby grew, the number of m and n changes (usually both increases in magnitude). The magnitude of m and n are not necessarily the same, as both number defines the capacity of an individual's brain. The larger the product of m and n, the bigger the capacity to think. Capacity of the human brain can be narrowed…

How the Brain works... Have you ever wondered what an individual’s brain works before they begin to abuse different substances? The Brain is an organ in the body that is capable of many, many things in all reality the brain controls your every movement thought and everything that you do in life. You can’t even do a simple task without your brain telling you how to do it, things even such as breathing. Then to think how all of this can change just by deciding to abuse drugs or alcohol. It…

information of all these clips, a data bank was created. Thus, when a subject watched a short video clip, the brain activity at the visual cortex was analyzed by the machine and an average image appeared on the computer screen. The odds of this happening by chance are zero percent. Thus the conclusion was made that certain, detailed areas of the primary visual cortex are excited when a specific detection of motion and image is made (1). The movies were shown and the computer could see what the…

As neuroscience research progresses, the concept of the mind becomes of critical importance. The mind is usually considered to be a separate, nonmaterial entity compared to the physical neurons within the brain. However, the field of neuroscience is finding many connections between the physical nature of the brain and the supposed non-physical aspect of the human mind. In a sense, neuroscience seeks to understand the functioning of the mind in terms of the physical neuronal firings of the brain.…

better view of how the human brain develops than ever before. And what they’ve found is that in most people, the prefrontal cortex and its links to other regions of the brain are not fully formed until age 25”(Greenblatt par. 5). This quote shows us that at the age of 18 our brain isn’t fully developed, however at the age of 25 it is fully developed which is when the prefrontal cortex links with other parts of the brain which helps with our decision making. So when we’re 25 we can make better…

adolescents, but the failure of this response to subside over time may be indicative of anxiety (Casey 20). Structural MRI studies of adolescents with anxiety disorders have shown structural anomalies in the superior temporal gyrus, the ventral prefrontal cortex and the amygdala (Paus…

The five main parts of the brain are:- Midbrain, Pons Varolii, Medulla Oblongata, Cerebrum and Cerebellum The midbrain is forms part of the brainstem (along with the medulla oblongata and pons varolii). It is responsible for your level of consciousness. The midbrain consists of two stalk-like bans that come out from the base of the cerebrum and lead into the pons varolii. It contains both grey and white matter. The pons varolii is located just below the midbrain and is responsible for…

When I read what happens when your hippocampus is damaged, my mind went to a movie I just watch. In 50 first dates Drew Barrymore plays a woman who can’t form new memories because she was in a crash in which she received a head injury. We can assume from the movie that she has injured her hippocampus. Since her hippocampus was damage it cause her to have ametrograde amnesia which means she can no longer make new long term memories since the crash. This is occurring because the switching station…
