Neuroimaging studies indicate that exercise may influence changes in brain structure and function. [94] Some investigations have linked low levels of aerobic fitness in children with impaired executive function when older as adults, but lack of selective attention, response inhibition, and interference control may also explain this outcome. [96]
Endorphins play a major role in the body's inhibitory response to pain. Research has demonstrated that meditation by trained individuals can be used to trigger endorphin release. [38] [failed verification] Laughter may also stimulate endorphin production and elevate one's pain threshold. [39]
Sometimes, the episodes may switch between emotional states, resulting in the patient crying uncontrollably before dissolving into fits of laughter. The pseudobulbar affect, also referred to as emotional lability , should not be confused with depression .

The combination of dopamine, serotonin and oxytocin is already pretty dreamy, but the brain takes that natural high to the next level when you reach the big O by releasing endogenous (i.e., made ...
Relief theory suggests humor is a mechanism for pent-up emotions or tension through emotional relief. In this theory, laughter serves as a homeostatic mechanism by which psychological stress is reduced [1] [3] [7] Humor may thus facilitate ease of the tension caused by one's fears, for example.
Enlargement of the ventricles, sulci and fissures is common in non-pathological aging. [6] Changes may also be associated with neuroplasticity, synaptic functionality and voltage-gated calcium channels. [7] Increased hyperpolarization, possibly due to dysfunctional calcium regulation, decreases neuron firing rate and plasticity.
Paradoxical laughter has been consistently identified as a recurring emotional-cognitive symptom in schizophrenia diagnosis. Closely linked to paradoxical laughter is the symptom; inappropriate affect, defined by the APA Dictionary of Psychology as "emotional responses that are not in keeping with the situation or are incompatible with expressed thoughts or wishes".
