Do you ever wonder what goes through infant’s minds and how they process everything around them? Well according to recent studies done by students at Harvard Medical School, infants have…

Following a hectic, fast paced, eight-hour work shift, which began at four in the morning, I find myself tired, sore, and upset. The slightest of mistakes, or other driver’s foolishness, causes an exaggerated, overdramatic response. Three distinct scenarios cause this response: cars who cut me off at the last second to make a turn, individuals who refuse to use their blinkers, and worst of all, drivers who pull out of a side road, conscious that I am traveling over 45 miles per hour. Rather than…

This part of the limbic system is very small, consisting of less than 1% of the brain, and is about the size of a kidney bean. The hypothalamus regulates our autonomic nervous system (also known as the ‘fight or flight’ response). It does this by regulating the release of hormones, the effects of which include control of heart rate, breathing, digestion, and blood pressure, among other things. The hypothalamus also controls the pituitary gland, which releases hormones…

definition of flight-or-fight. The adrenal glands are the producers of epinephrine in the body, most commonly known as adrenaline. In stressful situations your adrenal glands secrete adrenaline into your blood, increasing your heart rate, muscle strength, blood pressure and sugar metabolism, while also starting the flight-or-fight response in the brain. The flight part of the response is when your instinct is to disassociate yourself from the situation, trying to leave or avoid it. The flight…

induce certain responses cognitively. Take for example exam situations, where timing can be as early as 9 o’clock in the morning or as late as 7 o’clock in the evening. With these variable times, which the individual has no control over, performance could be lowered. Additionally, with the stress of exams, retaining information and expected to perform well a response like fight or flight could happen. For me I found this part very compelling, as I had not registered that fight or flight could be…

comes to escaping life threatening situations, but it is evident that escaping life threatening situations comes from the many natural characteristics such a sense of place, mental characteristics, and the fight-or-flight instinct.…

body. What was I afraid of? Absolutely nothing. So how can I be afraid of nothing but still be affected by fear? Well, humans as well as other animals have a natural response to moments where they feel like they are in danger, we know this as our “fight or flight” response. However because I have anxiety, this “fight or flight” response can be triggered…

Walter B. Cannon (1871-1945) "A quick and unconscious neurological response to a perceived threat that stimulates defensive behavior." He is an American Physiologist and Neurologist that became interested in the physical reactions of his laboratory animals when under stress. He studied the digestion of his animals and noticed that when an animal was frightened or scared, there would be physical changes on the stomach. Then he went on to study all of the various physiological reactions to stress…

to the amygdala, which provides a measure of emotional output that is appropriate, based on the analysis of the prefrontal cortex. This experience is then carefully stored in the hippocampus. It may take a few moments to calm down after the stress response is…

of the brain and the spinal cord. The brain is the master control center for the whole body. It receives impulses that provide information about the body’s internal and external state. When this takes place, the brain sends messages to enable a response to repair, react and retrieve information in order to handle the reactions that is taken place. The nervous system can be described much like a captain of a ship. It is through the captain that orders are handed down and actions begin to take…
