The Laboratory Of Neural Systems

In the article titled, “Secrets of the Brain” published in the February 2014 issue of National Geographic, we learn that there have been many advances in understanding the inner workings of our brains. One of the leading scentists, Van Weeden, is working hard to understand the connections that occur within our heads.

Since the dawn of the age of technology, humanity has made massive progress in the study of the human brain. Specifically, humanity’s new technology has led to revelations about the way the brain functions, and continues to discover the neurophysical reasoning behind human actions. These new discoveries continue to disprove previous theories, and have now begun to affect the way society views and perceive criminal law and the way it operates. In his book Incognito: The Secret Lives of the Brain, David Eagleman argues that there is a deep problem regarding how we think about whether it makes sense to blame people for their actions. Eagle argues that, in light of recent technological medical advancements, the existence of free will is beginning to seem highly improbable, and that both simple and complex actions can be traced back to their neuroscientific basis, without first bypassing the conscious mind. In this paper, I will argue that the theory and reconsideration proposed by Eagleman is, in fact, accurate, and a highly probable proposition for the future of the legal system.

The brain has many different parts and functions which do many different tasks. The Premotor Cortex is an area in the brain responsible for planning movement. Signals travel to the back of the brain then are processed and sent down a pathway to the Premotor Cortex to complete an action. Researchers have found ways to simplify the process in which information is  received in the Premotor Cortex. The New York Times article gives information about two scientist’s discoveries, the testing of their discoveries, the results of the tests, and the benefits of their ideas.

The graph showcasing Rizzo’s neural activity shows very low neural activity, highly suggesting that the neuron is not “tuned” to respond to this particular action. The low activity is likely due to the fact that, it’s a wooden block something that does not appear in a macaque monkey’s everyday life out in the wild.

A child’s brain is complexly plastic, meaning that it is adaptable to growth and reorganization due to its various experiences. In the movie, “The Secret Life of the Brain: Episode 2: The Child’s Brain: Syllable from Sound,” (PBS, 2002), several examples of nature and nurture were given to help prove that the brain is able to do amazing things from being able to recognize different languages, to overcoming difficulties when it is damaged or partially removed. Through the dynamic interaction of nurture and nature, human development occurs.

Neurons in the brain are extremely busy sending electrical signals from cell to cell telling the brain what to do. If these electrical signals are interrupted or abnormal, a seizure will occur. If it occurs throughout the brain, it is considered a generalized seizure (Grand Mal), and if it occurs in a localized area, it is called a partial seizure. If someone experiences more than two seizures, it is then considered epilepsy (AKA: Seizure Disorder).

Inside human brains contain around 100 billion neurons, which primarily connect to other neurons in order to communicate. Nevertheless, neurons help us perform simple, everyday tasks like answering your telephone or opening a door. With the help of many different structures, neurons, for the most part, let us communicate efficiently. (cite,book)

Decision neuroscience is a practice that employs neuroscience methods to examine concepts in social sciences. In a typical study, variables are selected from economic or psychological models. These variables are then measured or manipulated and identified with neural correlates. The neuro-economic approach shapes major economic variables especially in subjective values. As human beings, we are continually making decisions. The advent of poor decisions is the reason behind many disorders such as schizophrenia and addiction. The use of neuroscience methods makes it possible to understand decision making (Smith & Huettel, 2010). As much as decision neuroscience or neuro-economics is relevant in understanding decision making, there are challenges associated with this approach. The focus of this essay is to look at

It was surprising to me that Neuroscience is not just about biology, indeed is an interdisciplinary field that mix biology, chemistry, physics, computer science, psychology, history, philosophy, etc, to have a complete understanding of how the brain works.

Neuroscience is the study of the nervous system; it also has to do with any or all sciences such as experimental psychology and neurochemistry. It focuses on the brain and the impact it has on cognitive functions and behavior. Neuroscience is also known as neural science, it helps us get a better understanding of what happens with people who have a neurological disorders. The three main goals for neuroscientist: first, to understand the human brain, second, to understand the central nervous system and be able to describe how it develops, matures, and maintains, third, to be able to understand neurological and psychiatric disorders and prevent them or cure them.

Neuroscience is a fascinating area with a limitless possibility of understanding and uncovering to resolve so many unanswered questions. I have elected to pursue research in the field of neuroscience because I relish the approach of logical thinking to satisfy the curiosity of knowing things about me and the world around me. Although in recent years, a large number of breakthrough research has led open to the advancement in the diagnosis and therapeutic approaches for several neurological disorders and cancer such as glioma, there are a lot more to discover and untangle. Therefore, I decided to pursue my research in understanding such life-threatening neurological diseases.

Neuroscience, commonly referred to as Neural Science, is the study of the way the nervous system develops, how it is structured and the functions of it. Scientists put emphasis on the brain and the impact it has on behavior and cognitive functions. These scientists approach a closer look on the reactions the nervous system has when humans have neurological, psychiatric and neurodevelopmental disorders. The entire concept of neuroscience is addressed as a subdivision of biology. It is applied to chemistry, cognitive science, engineering, mathematics, linguistics and more. Scientists say that neuroscience is identical as neurobiology but there is a difference between the two conceptions. Neurobiology focuses mainly on the biology of the nervous system and neuroscience emphasizes on any portion of the nervous system. Neuroscientists have various fields of study that include cellular, functional, computational and medical aspects of the nervous system.

The most critical element of a Brain Machine Interface (BMI) is the recording and processing of the neural signal. We use an invasive neural signal recording to achieve higher performance of the BMI and to obtain better resolution. We will be recording the neural signal on central sulcus located in the cortex region of the brain. This recording is referred to as Electrocorticography (ECoG). We will be using subdural grid electrodes (surface electrodes) with 48 contact points spanning across the upper limb region of the central sulcus. The signal will be picked up by the electrodes and it will be transferred to the signal processing unit through the encapsulated leads. The leads will be connecting the
