Alternatively, synesthesia may arise through "disinhibited feedback" or a reduction in the amount of inhibition along feedback pathways (Grossenbacher & Lovelace 2001).It is well established that information not only travels from the primary sensory areas to association areas such as the parietal lobe or the limbic system, but also travels back in the opposite direction, from "higher order ...
Mirror-touch synesthesia is found in approximately 1.6–2.5% of the general population. [6] Mirror-touch synesthetes have higher levels of affective and pain empathy than those without the condition, though cognitive empathy differs from person to person. [7]
Pain empathy is a specific variety of empathy that involves recognizing and understanding another person's pain. Empathy is the mental ability that allows one person to understand another person's mental and emotional state and how to effectively respond to that person.

In the late 1990s, researchers began to turn their attention towards grapheme-color synesthesia, one of the most common [23] [24] and easily studied forms of synesthesia. In 2006, the journal Cortex published a special issue on synesthesia, composed of 26 articles from individual case reports to functional neuroimaging studies of the neural ...
Substance P has been associated with the regulation of mood disorders, anxiety, stress, [31] reinforcement, [32] neurogenesis, [33] synaptic growth and dendritic arborisation, [34] respiratory rhythm, [35] neurotoxicity, pain, and nociception. [36] In 2014, it was found that substance P played a role in male fruit fly aggression. [37]

When people with fibromyalgia are subjected to intense stimuli, they experience sensory overload in the form of pain. It is theorized that abnormal activity of the left dorsolateral prefrontal cortex and reduced production of or reception to serotonin are partially responsible for the sensation of pain in response to intense stimuli.
