What is anxiety? Anxiety is a natural reaction occurring at a certain point in the stress response when the sympathetic nervous system and the hypothalamic-pituitary-adrenal (HPA) axis start working at a high capacity. Emotionally anxiety insights fear (neurologically fear can be defined as the memory of danger) and some side effects of this can include feeling tense, uneasy, being short of breath, having an increased heart rate, sweating and chest pain (however chest pain only happens...Read More...

Sorry that I haven't posted in a while this was supposed to be the topic of last week's post which I though I published but evidently was deleted instead. I will try and re-do this to the best of my ability but I do not remember all of my sources. Sleep is a part of our everyday routine and has a huge variety of applications to brain functions like communication, learning, creating new memories, concentration, et cetera. It is as essential to surviving as food and water and is needed by...Read More...
Although it is not directly related to my inquiry on the relationship between exercise and cognitive functions, sleep is a neurological necessity that also has some very interesting relationships with exercise. Not only does sleep replenish the body and mind but is also has huge effects on how effective recent exercise will be. Today I will address what sleep does, exactly what it is, and how it enhances physical gains (through exercise). Last week I spoke on the potential of further mirror...Read More...

Last week I focused on how exercise can reduce stress by causing or rather replacing the stress with other types of stress. At the end I got on to the topic of the neurological similarities (in terms of which neurons are fired) between doing something and watching that thing done. This week I have decided to centre an entire post around the concepts of empathy and "Mirror Neurons." I will start by defining mirror neurons, explaining how they work, and then relating them to exercise. I will...Read More...

For my second round of research I have decided to stay on the course of what I have been doing for the past few weeks. I am fascinated with neuroscience and plan to stay the remainder of this year and, so far as I am thinking now, the entirety of next year as well focusing on this area of study; on the premise of exercise's effect on the brain in varying respects. I may also touch on how other components of our lives, environments, and stimuli that we are exposed to affect neural functions.Read More...

Research 1.4 The Spark

Ben Laird (LFAS)
Research 1.4 The Spark and how it relates to 1.3. Last week, during research section 1.3, I decided to take a break from reading scholarly research articles and coming up with a combination of their conclusions and my educated filling in of the gaps; I decided to read a book based of a similar project, albeit more in depth than mine. Over the last week I have been reading the book "Spark" written by Dr. John J. Ratey. This book subtitled "the revolutionary new science of exercise and the...Read More...

With exercise being such a broad term (It literally means an "activity requiring physical effort") it would be a gross generalization if I were to speak of all of exercise as one thing. So, instead, I will break it up. Some questions that I though of while researching this are listed here: Is there an optimal type of exercise? Which types of exercise benefit the brain and in what ways? How do different types of exercise differ in their neural effects? This week, my focus was predominantly...Read More...

This week's research is pertaining more to background knowledge on the inner workings of the brain than anything else. As it is relatively removed from the correlations between exercise and the brain, it is not really under the realm of research I am doing, it is, nonetheless imperative that I understand the workings of the brain, especially brain biology and neural pathways (in depth brain chemistry and such is of the complexity that leaning it will be an ongoing project) before I start my...Read More...

The focus last week was on the general workings of the nervous system and understanding neural pathways, how they are created, and their relation to fitness. I found this research both interesting and informative and though that it leads nicely towards the topic of the BDNF, which I have been wanted to look into for a while. This week’s research consists of learning about BDNFs (brain-derived neurotrophic factors) and their correlations to fitness, depression, and obesity. In previous posts...Read More...

Research 2.1 The components of the nervous system, neurons, and neural pathways. Last week I explained the physical structure of the brain as well as some other varying neurological concepts such as neural plasticity and some other neural processes. To quickly recap here are two pictures that show the major components of the physical brain: This week's focus consists of two main components. The first is the general workings of the nervous system. Most aspects of neuroscience reside in the...Read More...
