Lux – Light; pel-lucidem

Lux – Light; Pellucidum

The middle of the human brain contains a membrane structure that separates the two halves of the cerebrum. This membrane, a septum, so fine that it allows light to pass through it, it is almost translucent; pel-lucid, named in Latin; the septum pel lucidum, i.e. the dividing wall that is translucent.

Absence of the septum pellucidum occurs in certain congenital conditions and because the septum is involved with formation of the tracts concerning vision, it is often associated with blindness, and incidentally many other neurological problems.

I have included the X-ray of a newborn baby with congenital absence of this structure as well as absence of other brain structures. The Chest X-ray itself was normal.

The image consists of two base images; a red flower, colour inverted, and a layer of rusty iron is subtracted. Light (lux in Latin) is provided by a picture of a candle overlaid to give focus to the image.

  1. wow. stunning image and great information…

    do you ever see a direct link between excitotoxins like msg and aspartame and brain health? i am one of those ultra-sensitive ones, with feet swelling before leaving the table (msg)… and have had two visual scares after drinking aspartame-sweetened bevs… inquiring minds want to know!

    on to the third post!

    Even though this was published in November, it has a Christmassy look to it. Maybe I am influenced in that interpretation by it being so close to the holiday?

    It sounds like a very disturbing condition to be born with, Tony.

      Last year I tried publishing a very “christmassy” picture and I thought it was most unsuccessful. so I’m pleased this one has come through as right for the time. I hope yours is a peaceful and indeed joyful time. I thought your latest pictures were lovely.
