As stated previously, the changes in neural oscillations can contribute to the knowledge of what a steady state in an individual looks like, especially because it changes based on the person, as well as contributing to the imbalance of the nervous system and physiological function. Moreover, the brain can control the heart rate through the ...
Mass effect such as brain tumor, infarction with edema, contusions, subdural or epidural hematoma, or abscesses all tend to deform the adjacent brain. [citation needed] Generalized brain swelling can occur in ischemic-anoxia states, acute liver failure, [9] hypertensive encephalopathy, hypercarbia (hypercapnia), and Reye hepatocerebral syndrome ...
Functional MRI and PET scan are the most common techniques that use haemodynamic response to map brain function. Physicians use these imaging techniques to examine the anatomy of the brain, to determine which specific parts of the brain are handling certain high order functions, to assess the effects of degenerative diseases, and even to plan ...
The theory offered a physiological explanation for the previously observed effect of psychology on pain perception. [ 10 ] In 1968, three years after the introduction of the gate control theory, Ronald Melzack concluded that pain is a multidimensional complex with numerous sensory, affective, cognitive, and evaluative components.
Hans Selye was the first to coin the term "general adaptation syndrome" to suggest that stress-induced physiological responses proceed through the stages of alarm, resistance, and exhaustion. [7] The sympathetic branch of the autonomic nervous system gives rise to a specific set of physiological responses to physical or psychological stress.
Transcranial direct current stimulation (tDCS) is a form of neuromodulation that uses constant, low direct current delivered via electrodes on the head. This type of neurotherapy was originally developed to help patients with brain injuries or neuropsychiatric conditions such as major depressive disorder.
The ischemic (ischaemic) cascade is a series of biochemical reactions that are initiated in the brain and other aerobic tissues after seconds to minutes of ischemia (inadequate blood supply). [1] This is typically secondary to stroke , injury, or cardiac arrest due to heart attack .
The lower the stress levels are in the body, the less likely the allostatic load model will have a significant effect on the brain and health. Although, an increase in stress levels results in an increase in stress on the brain and the health of individuals, making it more likely for the body to have significant effects on homeostasis and cause ...
