  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. [39]

  3. β-Endorphin - Wikipedia

    en.wikipedia.org/wiki/Β-endorphin

    β-Endorphin (beta-endorphin) is an endogenous opioid neuropeptide and peptide hormone that is produced in certain neurons within the central nervous system and peripheral nervous system. [1]

  4. Luteinizing hormone - Wikipedia

    en.wikipedia.org/wiki/Luteinizing_hormone

    Part of the inhibitory action of endorphins on GnRH-1 release is through inhibition of these GABA neurons. Rupture of the ovarian follicle at ovulation causes a drastic reduction in estrogen synthesis and a marked increase in secretion of progesterone by the corpus luteum in the ovary, reinstating a predominantly negative feedback on ...

  5. Releasing and inhibiting hormones - Wikipedia

    en.wikipedia.org/wiki/Releasing_and_inhibiting...

    Releasing hormones and inhibiting hormones are hormones whose main purpose is to control the release of other hormones, either by stimulating or inhibiting their release. . They are also called liberins (/ ˈ l ɪ b ə r ɪ n z /) and statins (/ ˈ s t æ t ɪ n z /) (respectively), or releasing factors and inhibiting fac

  6. 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 .

  7. μ-opioid receptor - Wikipedia

    en.wikipedia.org/wiki/Μ-opioid_receptor

    It is an inhibitory G-protein coupled receptor that activates the G i alpha subunit, inhibiting adenylate cyclase activity, ... Endorphins (e.g., β-endorphin) [41]

  8. Gate control theory - Wikipedia

    en.wikipedia.org/wiki/Gate_control_theory

    The firing of the projection neuron determines pain. The inhibitory interneuron decreases the chances that the projection neuron will fire. Firing of C fibers inhibits the inhibitory interneuron (indirectly), increasing the chances that the projection neuron will fire. [4] Inhibition is represented in blue, and excitation in yellow.

  9. Excitatory postsynaptic potential - Wikipedia

    en.wikipedia.org/wiki/Excitatory_postsynaptic...

    At the same time, GABA is the most common neurotransmitter associated with IPSPs in the brain. However, classifying neurotransmitters as such is technically incorrect, as there are several other synaptic factors that help determine a neurotransmitter's excitatory or inhibitory effects.
