First of all, I thought it was very interesting to learn that there are 3 distinct parts of the human brain that have evolved over time. These three anatomical puzzle pieces each serve various purposes ranging in complexity. The brainstem is the oldest piece of our brain and it takes care of many functional aspects of our daily lives such as breathing, sleeping, and regulating heart beats. On top of our brain stem is our mammalian brain which all mammals have. It gives us all the basic instincts that we need for survival in the wild such as our sex drives, flee or fight instincts, and knowledge of when to eat and how to acquire food. Also apart of our mammalian brains is our amygdala which is what makes us to experience emotions, our hippocampus which allows us to process short-term memories into long-term memories, and our thalamus which is in charge of processing everything that can sense in our environment. As complex as our mammalian brain sounds, it is no match for our human brain that's folded atop of it called the cortex. The cortex is a complex layer of tissue that is in constant communication with other areas of the brain and body. Different sections of the cortex are responsible for different activities such as vision, speech, and memory. The cortex is the most sophisticated layer in our brain and is what separates us from other mammals. Only a few months after they are born, most animals are considered adults. Humans are not like this. Once humans are born, we
During brain development, beginning in the womb into adulthood, all of these cells must be grouped and organized into specific networks, which create the architecture of the brain (Perry & Szalavitz, 2006). The brainstem, the diencephalon, the cortex and the limbic system are the four major parts of the brain. The brain is organized from the inside out, thus, “the lower and most central regions of the brainstem and diencephalon are the simplest” (Perry & Szalavitz, 2006, p. 21) and are also the first to form, therefore, developing first as the child grows and develops (Perry & Szalavitz, 2006). As the brain develops upward and outward, the limbic system becomes more complex and the cortex is the crowning achievement of the brain structure (Perry & Szalavitz, 2006). These four areas of the brain are organized from top to bottom and inside to outside, although these four areas are interconnected, each one controls different functions such as the brainstem controls body temperature, heart rate and blood pressure, as well as respiration. The limbic system and diencephalon control emotional responses that help to guide one’s behavior such as fear, love, joy and anger. The cortex, the top part of the brain, regulates the complex and high functions such as speech, critical thinking, and decision-making (Perry & Szalavitz, 2006). The
Going back to the gray matter, the outer layer of gray matter is the frontal cortex. This is where we make decisions and where we do much of our conscious and complicated thinking. Phineas Gage, a renowned neuroscience patient in the 1800, was hit with a iron rod to the head, yet minutes after he was still able to move and act normal (Fleischman 6). The only thing was that he could not make decisions. When given a $1000 for the pebbles he collected, he angrily refused the deal( 19). He was not able to make the decision of getting the money or not. Neuroscientists have learned so much of the brain that has helped us understand our own brains and the people around us. From this scientist learned that the sections of the brain had parts and functions such as language and comprehension(65). Lastly they learned about germs and that you need to make sure to disinfect your tools(17). Without this our technology that is here would not be as progressed if we did not know this. All of these components helped us understand the teen brain just a little bit
The brain is the most complicated part of the human body. I will begin explaining certain parts and their
When it comes to the topic of having a growth mindset, most of us will readily agree that students who are praised are motivated to learn. Where this agreement usually ends, however, is on the question of how they are praised. Whereas some are convinced that praising students for their intelligence will motivate them to learn, others maintain that encouraging them for their efforts has a better impact on their motivation.
The human brain is a feat of evolution: it has allowed humans to have complex thoughts, conscience, build tools, create fires, and much more. Humans did not acquire this simply by chance. Evolution throughout our ancestral past has shaped and moulded the human mind to its state. The earliest of ancestors, including apes, had very small brains, but as evolution progressed, so too did the human brain. The rapid progression of human intelligence has been attributed to environmental changes causing humans to change with their surroundings for survival. This lead to the expansion of specific areas of the brain, vastly differing maturation of humans compared to our
The brain stem or the medulla is the closest to the spinal cord. The brainstem is responsible for most of the human bodily functions. The brain stem is critical for human survival and normal human functions. The brain stem is also responsible for information of pain and touch from the head and neck; it is also responsible for the inputs from the face and the mouth. Reticular formation is a group of neurons, nuclei, that are important for sleep and wakefulness. In reticular formation there is nuclei that are a major source of neurotransmitter serotonin. Serotonin is important for regulating mood and activities.
An ignorant thing to say is “forget the old and focus on the new.” Civilization has set forth the belief that when something is old and non-civilized, then it has no use. Nowadays, human beings are looking for modern and industrialized ways to teach themselves or get information into the brain without focusing on the brain itself. It is true that the human brain has greatly evolved to the point where human beings can produce all kinds of machines, but at the same time, they still rely on the primitive brain to make basic decisions like eating or sleeping. The primitive brain is at the lowest part of the brain, just above the spinal cord, and its functions is to regulate vital body functions such respiration and it also sends sensory information
I have always had a passion and interest in working with the unknown. When I was in high school, I always made sure I was taking science classes that interested me, and would help me decide on what I wanted to major in college. I chose neuroscience as my major because it is a subject that continues to fascinate me. Neuroscience is the study of how the nervous system develops, its structure, and what it does. I want to focus on the brain and its impact on behavior and cognitive functions. I want to go into clinical neuroscience (looking at the disorders of the nervous system) or cognitive neuroscience, which studies the higher cognitive functions and underlying neural bases. With a neuroscience major, I would like to pursue a career in clinical research, do research for the National Institute of Health, work for the CDC and specialize in neurological disease, and/or run a clinical research project in another country. I want to pursue a career in one of these areas because I want to dedicate my knowledge, skills, and time to helping people and the world of science. I want my work to make a positive impact on society and be beneficial for the forthcoming generations. I want to help people and discover new things that will help those in need. I am motivated every day to continue working hard by realizing there are still more things to be discovered and that it could be done by me.
The human brain is an amazing device. It controls everything we do. It controls our bodies, how we communicate, how we function. Our brains our
Let’s begin by discussing the parts and function of our brains. The neo cortex is the largest part of the brain and the most important. This part of the brain is divided into four different sections: the temporal lobe, occipital lobe, parietal and the frontal lobe. These four sections are located on either the right or left hemisphere of the brain they are connected by axons that send messages to and fro between both hemispheres and to specific parts of the brain then to the body. Our neo cortex is what makes us so different from our primate cousins.
Firstly, it is important to understand the evolution and development of human brain. An interesting idea is that our human brains are becoming smaller in size through evolution of time. It is commonly believed that more content requires bigger space. Let 's take an example. A bowl that needs to fit ten identical objects needs to be bigger to a bowl that only needs to fit five identical objects. Likewise, our human brain has continued to develop through evolution and has much more complex capabilities as well as content to carry since the birth of our species in the Stone Age. Now
Our brain is incredible, it is made up from 73 percent water and 2 percent dehydration that has an act our memory, attention, and numerous other cognitive skills. There are many parts of the brain that not everyone knows about. Now, in alphabetical order, for example, the first is amygdala it is an almond-shaped mass of gray matter inside cerebral hemisphere, this is involved with emotions. Auditory text, is where the brain processes information that is received from hearing. Broca’s area, a section in the frontal lobe of the dominant hemisphere which is usually on the left of the hominid brain with functions linked to speech production. Cerebellum, the part of the brain that is in the back of the skull in vertebrates. Some of the cerebellum
They regulate the functions that ensure the body's survival — blood circulation, digestion, respiration, bio-assimilation — but also emotions like fear when faced with danger. The most recent parts of the brain, those which are particularly developed in the human species, are the frontal lobes that enable reflection, knowledge, imagination, and control of emotions. For a well-balanced personality, emotions must be able to develop normally, and the brain must learn to recognize and control
The limbic system is located between the brain stem and the right and left hemispheres of the brain. The limbic system regulates memory, emotions, fear, and our reactions to rewards and punishment.
You live and you learn, from the moment that we breathe our first breath, we are assimilating and are acquiring information. Life changing and profound learning experiences happen before we can even speak, as children our learning process is grandiose. Harvard University published a series of summaries on Child development. One of these articles mentions that “The basic architecture of the brain is constructed through an ongoing process that begins before birth and continues into adulthood.” ("InBrief: The Science of Early Childhood Development," n.d.).
