Brain Plasticity And Its Effects On The Human Body

There are many symptoms associated with the physiological responses of the fight-or-flight including dilation of pupils, increased and more rapid heart rate, and acceleration in the respiratory system. The fight-or-flight response is a very important and crucial response both mentally and physically that is a building block for the human body. Without it, humans may not be as adapted to the dangerous and stressful environment we call our world. Finally, to summarize the steps of the fight-or-flight response. First, a threat or stimuli are perceived by the retina and signals are sent to the brain. Next, the brain processes the signals and determines whether the threat is real. Then, the adrenal medulla is sent synapses from the cerebrum and secretes a liquid with high levels of adrenaline called epinephrine. After that, the secreted adrenaline is mixed with glucose. Next, the adrenaline and glucose are rushed throughout the bloodstream and to the muscles. The muscles then tense up and are given an extra boost of strength and speed. Lastly, the muscles are used to either fight or

Fear influences human behavior and the way people react to situations. When fear is perceived, the body starts to sweat, and a “fight or flight” reaction occurs. The body temperature is lowered down. The heart starts to pound and the body releases the hormone epinephrine into the bloodstream when it perceives a threat. This in turn increases the heart rate so that it moves blood into other parts of the body that may need it to act in the face of fear. Another side effect is shortness of breath, when nerves around the ribcage and torso are

The concept of neuroplasticity has long been questioned. The term of “neuroplasticity” did not even come about until the mid-late 20th century. When the term “plastic” was used to describe the brain by a select few neuroscientists, they were laughed at and the term was never thought of as a description for the human brain. The human brain was seen as a closed circuit and one that once you had it, you definitely had it. Scientists thought the brain would not develop anymore past a certain point in your life. Norman Doidge brings the concept of neuroplasticity into reality in his book “The Brain that Changes Itself,” a book about the triumphs in the frontier of brain science.

Consistent with the idea of learning and the brain’s interaction with the environment, neuroplasticity is the idea that the human brain can change and grow, that it can modify itself to compensate for weak spots and expand limits (Cockrell, 2007). For example, it was once thought that neuron production slows down exponentially in adulthood, but research reveals that this is not the case. Research has found that the brains of aging cancer patients were still able to produce new neurons (Cockrell, 2007). The human brain is an extremely complex organ. Inside the average human brain, there are 200 billion neurons. These neurons allow for trillions of connections (Arrowsmith, 2013). Arrowsmith (2013) discussed Mark Rosenshwag, a neuroscientist who conducted an experiment with rats. Rosenswag placed the rats in a stimulating environment and found that rats were better learners because of the stimulation. More importantly, he noted that the brains of the rats being studied changed

drawn from this finding. One is that no shift from one hemisphere to the other has occurred

It is full of comprehensive and engaging style; well reference and scientifically proven, summarizes the current revolution in neuroscience and neuroplasticity, and closes the gap that the old age or matured brain, which is unchangeable is changeable and malleable (plastic); extending it functions from one region to the other. Doidge engaging style of writing, scientific proves, and academic tone help to make the book persuasive.

There are three stages to plasticity, the first stage is your immature brain that you had at the beginning of your life organizes its self. The second stage is when your brain starts to learn something new or memorizes something. The final stage is when your brain makes up for a function that was lost. Your brain is so tremendous that it is made up of 100 billion neutrons that can send pulses at 250mph through the brain. Your brain is

In America, Cocaine dependence is an issue which involves nearly every one in three drug related emergency hospital visits, having various personal and social economic impacts (Martell, Orson et al. 2009). Many individuals who suffer have been found to have impaired cognitive functions and manifest a myriad of biological and neurological dysfunctions. The relationship between cocaine and cocaine dependence on brain physiology is its effects on particular brain regions and receptors leading to synaptic plasticity mediating altered ability of learning and consolidation [pic](Martinez, Narendran et al. 2007; Thomas, Kalivas et al. 2008; Mameli, Halbout et al.

Neuroplasty is The ability of the brain to adapt, to create workarounds and short cuts to make up for missing or damaged portions of the brain. It is amazing how the brain can grow new networks and nueral connections till the day we die. Our little brain cells oe neurons compensate for or imjuries ,diseases or birth defects. OUr brain adapts for and redesigns its self to accomplish normal tasks, Sometime by retraining but sometimes just natural. Our brain is more less plastic. So our brains are capable of re-engineering themselves. However there are limites based on the amount of damage and which parts are damaged, But overall our brains are pretty hardy.(MedicineNet.n.d.).

Neuroplasticity is the change of pathways in the brain that allows us to do certain activities and change the way we do them. It works through a connection of neurons that allow us to think and react.

Humans all share similarities brains to chimpanzees and mice. To understanding the long-term change of brain regulation, and particularly as they occur after birth, is crucial in determining the force that nutrition and environmental have on healthy development during stage of life cycles. Furthermore, most of human brains develop after birth. Environmental can the main affect that functioning our brain later in life (during early childhood and adolescence), environmental factor can either destroy the brain further and increase the risk of schizophrenia (long-term mental disorder). Mental disorder or mental illness caused by biological, psychological and social factors. When teenagers are having stressful day, they tend to use drug to relieve their stress out.

“[Fight or Flight] response is hard-wired into our brains and represents a genetic wisdom designed to protect us from bodily harm. This response actually corresponds to an area of our brain called the hypothalamus, which—when stimulated—initiates a sequence of nerve cell firing and chemical release that prepares our body for running or

The human brain is completely malleable. James Olds, a professor of neuroscience at George Mason University, says that even the adult mind “is very plastic.” According to him, “The brain has the ability to reprogram itself on the fly, altering the way it functions.”

The term plasticity is commonly defined as “the quality of being easily shaped or molded.” But when this term is used in the context of neural development, one may refer to this as brain plasticity and/or neuroplasticity, which means that the brain has the ability to change over a lifespan. Changes in one’s brain can occur by gaining knowledge (“exercising the mind”), memorization, stress, genes, hormones, and one’s environment.

The brain is a complex organ that is the central control center of the human body. It consists of three main parts, the forebrain, the midbrain and the hindbrain. Each part of the brain has a specific function; which include controlling and coordinating actions and reactions, allowing us to think and feel, and enabling us to have memories and feelings. Although all the components of the brain are vital, the brain would still able to function even if one part of the brain was damaged or removed. The reason for why the brain would still be able to function is brain plasticity; it is essential because it plays a key role not only humans survival but all living organisms survival, and it also impacts an organism's behavior.
