  2. Midbrain activation - Wikipedia

    en.wikipedia.org/wiki/Midbrain_activation

    Midbrain activation is a pseudoscientific training method claiming to allow the development of blind vision and to improve memory and concentration. The trick often works by training participants to see through blindfolds to give the illusion that they are reading objects without being able to see.

    They focused on the activation of the protein complex NF-κB in mice test subjects, which showed increased activation as mice test subjects aged in the study. This activation not only affects aging, but affects a hormone known as GnRH , which has shown new anti-aging properties when injected into mice outside the hypothalamus, while causing the ...

    en.wikipedia.org/wiki/Pretectal_area

    In neuroanatomy, the pretectal area, or pretectum, is a midbrain structure composed of seven nuclei and comprises part of the subcortical visual system.Through reciprocal bilateral projections from the retina, it is involved primarily in mediating behavioral responses to acute changes in ambient light such as the pupillary light reflex, the optokinetic reflex, and temporary changes to the ...

    This technique opens many interesting doors for future therapies. A potential challenge for this technique is that there is little transfer of gains from one section of skin to another. Many studies have been conducted, most with some kind of positive conclusion however, further studies need to be conducted sensory stimulation in dementia in ...

  6. Dopaminergic pathways - Wikipedia

    en.wikipedia.org/wiki/Dopaminergic_pathways

    The mesolimbic pathway transmits dopamine from the ventral tegmental area (VTA), which is located in the midbrain, to the ventral striatum, which includes both the nucleus accumbens and olfactory tubercle. [5] [6] The "meso" prefix in the word "mesolimbic" refers to the midbrain, or "middle brain", since "meso" means "middle" in Greek.

  7. Periaqueductal gray - Wikipedia

    en.wikipedia.org/wiki/Periaqueductal_gray

    Stimulation of the periaqueductal gray matter of the midbrain activates enkephalin-releasing neurons that project to the raphe nuclei in the brainstem. 5-HT released from the raphe nuclei descends to the dorsal horn of the spinal cord where it forms excitatory connections with the inhibitory interneurons located in Laminae II (aka the substantia gelatinosa).
