  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.

    en.wikipedia.org/wiki/Papez_circuit

    Semantic dementia is a rare degenerative disorder that exhibits defects in all semantic memory functions, including naming, single word comprehension and impoverished general knowledge, with relative preservation of other components of speech, perceptual and nonverbal problem-solving skills, and episodic memory. This may occur due to damage in ...

    In January 2008, Ragert et al. explored the impact of frequency of stimulation on sensory stimulation techniques to induce plastic changes. The study investigated if varying the frequency could be used to induce either Long-Term Potentiation (LTP) or Long-term Depression (LTD). LTP refers to the processes by which neuronal connections are ...

  6. Ventral tegmental area - Wikipedia

    en.wikipedia.org/wiki/Ventral_tegmental_area

    Neurobiologists have often had great difficulty distinguishing the VTA in humans and other primate brains from the substantia nigra (SN) and surrounding nuclei. Originally, the ventral tegmental area was designated as a ‘nucleus’, but over time ‘area’ became the more appropriate term used because of the heterogeneous cytoarchitectonic features of the region and the lack of clear ...

  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).
