Sudah lama Saya tidak memutakhirkan isi blog lagi, and i blamed Twitter for that :))

Kemarin Saya baru saja melihat film tv serial amerika Heroes, dimana ada salah satu tokoh bernama Emma yang bisa melihat suara sebagai warna (seeing sound as color) *Sebenarnya itu cuma salah satu type synesthesia, ada 20 kemungkinan  dari gabungan panca indera kita Dan Saya teringat akan sebuah artikel di dunia medis tentang Syneshesia. Menurut Wikipedia :

Synesthesia (also spelled synæsthesia or synaesthesia, plural synesthesiae or synaesthesiae)—from the Ancient Greek σύν (syn), “together,” and αἴσθησις (aisthēsis), “sensation“—is a neurologically based phenomenon in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. ^[1][2][3][4] People who report such experiences are known as synesthetes.

The Biological Basis of Synesthesia

Some scientists believe that synesthesia results from “crossed-wiring” in the brain. They hypothesize that in synesthetes, neurons and synapses that are “supposed” to be contained within one sensory system cross to another sensory system. It is unclear why this might happen but some researchers believe that these crossed connections are present in everyone at birth, and only later are the connections refined. In some studies, infants respond to sensory stimuli in a way that researchers think may involve synesthetic perceptions. It is hypothesized by these researchers that many children have crossed connections and later lose them. Adult synesthetes may have simply retained these crossed connections.

It is unclear which parts of the brain are involved in synesthesia. Richard Cytowic’s research has led him to believe that the limbic system is primarily responsible for synesthetic experiences. The limbic system includes several brain structures primarily responsible for regulating our emotional responses. Other research, however, has shown significant activity in the cerebral cortex during synesthetic experiences. In fact, studies have shown a particularly interesting effect in the cortex: colored-hearing synesthetes have been shown to display activity in several areas of the visual cortex when they hear certain words. In particular, areas of the visual cortex associated with processing color are activated when the synesthetes hear words. Non-synesthetes do not show activity in these areas, even when asked to imagine colors or to associate certain colors with certain words.

Synesthesia and the Study of Consciousness

Many researchers are interested in synesthesia because it may reveal something about human consciousness. One of the biggest mysteries in the study of consciousness is what is called the “binding problem.” No one knows how we bind all of our perceptions together into one complete whole. For example, when you hold a flower, you see the colors, you see its shape, you smell its scent, and you feel its texture. Your brain manages to bind all of these perceptions together into one concept of a flower. Synesthetes might have additional perceptions that add to their concept of a flower. Studying these perceptions may someday help us understand how we perceive our world.

Pesan Saya :
We all perceive the world differently, the same thing can be viewed from different angle and perspective. Think about that.

Cuz when you’re gone,
all the colours fade.
When you’re gone,
no new years day parade.
You’re gone,
colours seem to fade.
