what is synesthesia:
Synesthesia is the perception of a same feeling through different senses. The word comes from Greek and is composed of the words συν-(no), which means ‘together’, and αἴσθησις (aisthesis), which translates ‘sensation’.
For biology, synesthesia is a secondary or associated sense in which a stimulus is applied in a certain part of our body is perceived in another.
Psychology, on the other hand, believes that synaesthesia is the sense in which a perception, own a certain sense, is fixed by another feeling that affects another sense.
Synesthesia is a condition that can occur in an individual who is able to hear colors, see sounds or appreciate textures when you taste something. A synesthetic, for example, perceived spontaneously correspondences between shades of color, sound and taste intensities.
Synesthesia lives over the years. Scientific research argue that it is a dominant trait linked to the X chromosome, while other scientists consider that synesthesia occurs through a crossing of adjacent areas of the brain that process different sensory information.
As such, synesthesia is more common among patients with autism, but also certain Epilepsies can cause synesthesia perceptions.
Experiences Synesthesia, on the other hand, can be taken through the consumption of hallucinogens, such as LSD, mescaline, or certain fungi.
