Disinhibition

 

the abolition of internal inhibition in the cortex of the brain’s large hemispheres under the influence of a new, extraneous stimulus.

The concept of disinhibition was introduced by I. P. Pavlov. Excitation arising at a point on the cortex of the large hemispheres under the influence of an extraneous stimulus radiates through the cortex, takes over other points of the cortex, including inhibited ones, and abolishes the inhibition, transforming it to excitation. For example, a conditioned food reflex abolished by repeated use of a conditioned stimulus unaccompanied by an unconditioned one (that is, not reinforced with food), manifests itself as soon as a new, previously unused stimulus is added to the conditioned stimulus. Disinhibition may also result from positive induction. The phenomenon of disinhibition may also be observed in other parts of the central nervous system.

These traits are supposed to be maladaptative versions of normal personality traits (e.g., the Five Factor Model, FFM) and, in fact, it has been shown that Negative Affect, Antagonism and Disinhibition are aligned with Neuroticism, Agreeableness and Conscientiousness, respectively, while the links Detachment-Extraversion and Psychoticism-Openness are more modest (Watson, Stasik, Ro, & Clark, 2013).
Other studies have assessed the effects of AIE on risk-taking behavior, impulsivity, and disinhibition, all behavioral propensities that could promote experimentation with AODs.
This could be explained by the fact that increased CDR has been associated in the literature with obsessive thoughts about forbidden foods [21], increased appetite sensations [22], and risk of overeating episodes (i.e., disinhibition) [23].
The FBI-ALS is comprised of the negative scale (measures apathy, emotional flatness, and aspontaneity) and the disinhibition scale (measures behaviors like inappropriateness, impulsivity, and hyperorality).
A combination of two specific eating traits, namely, high cognitive control over eating (restraint) and low stress-resistant eating (disinhibition), is strongly associated with weight loss success in obese individuals without T2DM, subjected to a lifestyle intervention [12, 14].
Although disinhibition in the acute phase after stroke may be necessary to allow plasticity to a certain extent [3, 5, 58], it is possible that later on a normalization of excitability is a prerequisite for normal or near-normal (sensorimotor integration) and hand functions.
'An overall level of behavioral disinhibition is fueling this epidemic and is not necessarily associated with PrEP," he said.
According to Robert, M Julien, the author of "A Primer Of Drug Action," "nitrous oxide induces a state of behavioral disinhibition, analgesia, and euphoria." "One of the problems occasionally encountered when nitrous oxide is used for recreational purposes is that, unless the compound is administered with at least 20 percent oxygen, hypoxia (decreased oxygen content of the blood) can be induced."
This substance, like other synthetic cathinones, has psychoactive and sympathomimetic effects similar to amphetamines, besides possessing entactogenic properties such as sensorial intensification, increase in sociability, disinhibition and sexual arousal.
It evaluates 12 BPSD, including delusions, hallucinations, agitation/aggression, dysphoria/depression, anxiety, euphoria/elation, apathy/indifference, disinhibition, irritability/lability, aberrant motor behavior, nighttime behavioral disturbances, and appetite and eating abnormalities.
