  2. Endorphins - Wikipedia

    en.wikipedia.org/wiki/Endorphins

    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 .

  3. β-Endorphin - Wikipedia

    en.wikipedia.org/wiki/Β-endorphin

    [8] [17] Thus, the inhibition of GABA release by β-endorphin allows for a greater release of dopamine, in part contributing to the analgesic effect of β-endorphin. [8] [17] The combination of these pathways reduces pain sensation, allowing for the body to stop a pain impulse once it has been sent.

  4. α-Endorphin - Wikipedia

    en.wikipedia.org/wiki/Α-endorphin

    Endorphins are generally known as neurotransmitters that are released when the body goes into pain. [3] The three endorphins that play a role in this response are α-endorphin, β-endorphin (beta-endorphin), and γ-endorphin (gamma-endorphin) which are all derived from the same polypeptide known as pro-opiomelanocortin. [3]

  5. Enkephalin - Wikipedia

    en.wikipedia.org/wiki/Enkephalin

    In response to pain, norepinephrine, a hormone that is activated in fight-or-flight response, is released along with endorphins. [4] A 2017 study indicates that this polypeptide may be linked to brain functioning during the stress response , especially in the hippocampus and prefrontal cortex .

  6. Hypothalamic–pituitary–adrenal axis - Wikipedia

    en.wikipedia.org/wiki/Hypothalamic–pituitary...

    The HPA axis is responsible for modulating inflammatory responses that occur throughout the body. [12] [13] During an immune response, proinflammatory cytokines (e.g. IL-1) are released into the peripheral circulation system and can pass through the blood–brain barrier where they can interact with the brain and activate the HPA axis.

  7. Dynorphin - Wikipedia

    en.wikipedia.org/wiki/Dynorphin

    When prodynorphin is cleaved during processing by proprotein convertase 2 (PC2), multiple active peptides are released: dynorphin A, dynorphin B, and α/β-neoendorphin. [1] Depolarization of a neuron containing prodynorphin stimulates PC2 processing, which occurs within synaptic vesicles in the presynaptic terminal . [ 2 ]

    Or, in layperson terms, an intensely pleasurable response to sexual stimulation that involves both the brain (neurons) and the body (muscles). That said, Dr. Wise tells us that “orgasms exist on ...

  9. Opioid peptide - Wikipedia

    en.wikipedia.org/wiki/Opioid_peptide

    Exogenous opioid substances are called exorphins, as opposed to endorphins. Exorphins include opioid food peptides, such as gluten exorphin and opioid food peptides, and are often contained in cereals and animal milk. Exorphins mimic the actions of endorphins by binding to and activating opioid receptors in the brain. Common exorphins include:
