There was a brief rise of interest in transcranial direct current stimulation in the 1960s when studies by researcher D. J. Albert proved that the stimulation could affect brain function by changing the cortical excitability. [40] He also discovered that positive and negative stimulation had different effects on the cortical excitability. [41]
Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
CES was initially studied for insomnia and called electrosleep therapy; [9] it is also known as cranial-electro stimulation [10] and transcranial electrotherapy. [ 11 ] Due to the rise of pharmaceutical treatments for depression, anxiety and insomnia, such as Prozac in the 1980s and Ambien in the 1990s, CES was not a well-known treatment for ...
Some find the tingly autonomous sensory meridian response (ASMR) relaxing, while others find it irritating—either way, your brain is performing sensory magic. Why ASMR Feels Like a Pleasant ...
Craniosacral therapy (CST) or cranial osteopathy is a form of alternative medicine that uses gentle touch to feel non-existent rhythmic movements of the skull's bones and supposedly adjust the immovable joints of the skull to achieve a therapeutic result.
In psychology, relaxation is the emotional state of low tension, in which there is an absence of arousal, particularly from negative sources such as anger, anxiety, or fear. [2] Relaxation is a form of mild ecstasy coming from the frontal lobe of the brain in which the backward cortex sends signals to the frontal cortex via a mild sedative.
Neurotoxicity is a form of toxicity in which a biological, chemical, or physical agent produces an adverse effect on the structure or function of the central and/or peripheral nervous system. [1] It occurs when exposure to a substance – specifically, a neurotoxin or neurotoxicant – alters the normal activity of the nervous system in such a ...
However, in the three-year study, both groups of breast cancer survivors were observed to have similar gray and white matter volumes. Altered brain structure in chemotherapy patients provides explanation for cognitive impairment. [12] Another study in 2007 investigated the differences in brain structure between two adult, monozygotic twin females.
