What are Confounding Variables in healthcare and medical research,
confounding variables are factors or variables that can distort or influence the relationship between the independent variable (the factor being studied) and the dependent variable (the outcome)
What is a Cofounder in epidemiology?
a cofounder is a variable that is not the primary variable of interest but can influence the association between the exposure (risk factor) and outcome (disease or health condition) being studied.
What is the “multiple demand system” (MDS)
Domain-general fronto-parietal network in which the DLPFC seems to have superordinate cognitive control functions for various cognitive tasks
Epidemiology
the branch of medicine which deals with the incidence, distribution, and possible control of diseases and other factors relating to health.
Limbic
The limbic system often referred to as the limbic lobe isn’t actually a separate region of the brain but rather a collection of neural structures from various brain regions that all work together towards a variety of common functions. Some of these functions are emotion, behavior, motivation, memory, and learning.
Tell me about the location and function of the prefrontal cortex.
The prefrontal cortex (PFC) is the part of the frontal lobe that’s in front of or inside the motor cortex. It’s often called the “personality center” because it’s where we process information from our surroundings, compare it to past experiences, and react to it. The PFC is involved in many functions, but it’s most commonly associated with executive functions like decision-making, planning, problem solving, and self-control
What is Vagel Tone
Vagal tone measures how well the vagus nerve functions and is a key component of the parasympathetic nervous system. The vagus nerve is the 10th cranial nerve, and it runs from the brain stem to many parts of the body, including the heart, lungs, gut, and tongue. Vagal activity can cause a number of effects, including:
* Reduced heart rate
* Vasodilation and constriction of blood vessels
* Glandular activity in the heart, lungs, digestive tract, and liver
* Regulation of the immune system
* Control of gastrointestinal sensitivity, motility, and inflammation
Value of testing for C-reactive protein levels
Elevated high-sensitivity C-reactive protein levels—a biomarker of the body’s inflammatory reaction to acute infection.
What is C-Reactive Protein (CRP)?
C-reactive protein (CRP) is a protein produced by the liver in response to inflammation or infection. It’s one of a group of proteins called acute phase reactants that increase in response to inflammatory proteins called cytokines, which are produced by white blood cells
