“engage the visual, auditory and motor cortices” (Collins) These activities in the brain have been seen activating all at once during the use of an instrument and monitored with F.M.R.I known as Functional Magnetic Resonance Imaging and Positron Emission Tomography machines that display and record neurological signals in real time. Through the use of many regions of the brain, pathways strengthen and specify to better increase the rate and speed at which they can activate because, much like a…

Methamphetamine and its Effects on the Body and Brain Methamphetamine (n-methyl-1-phenyl-propan-2-amine) has a molecular weight of 149.237 g/mol and is an addictive man-made stimulant affecting the central nervous system (Methamphetamines: An Overview, n.d.). There are two different types of methamphetamine: l-meth (Levo-methamphetamine), and d-meth (Dextro-methamphetamine), which is the more common form.

Homeostasis - Blood Glucose Regulation Homeostasis refers to the (relatively) constant physiological state of the body despite fluctuations in the external environment. Homeostasis maintains a relatively constant physiological state by keeping functions such as temperature, blood pressure, pH levels, glucose concentration and many more of the body’s systems at safe levels. For example if a person has low or high blood sugar (hypoglycaemia or hyperglycaemia) their internal state is in danger…
