Progression To Childhood
In January 2009, a documentary was filmed which reported on Tatiana and Krista Hogan, and followed their progress up to their 3rd birthday. This documentary was released and aired in October, 2010. In this documentary, it was confirmed that Tatiana and Krista shared a thalamus which connected their brainstems. Through this shared brain tissue structure and the interconnected neurons one brain receives signals from the other brain and vice versa. This documentary also reported on experiments which were carried out which confirmed that visual cortex signals were received at the other brain. So in effect, one twin could "see" what the other twin was seeing, making them unique even among craniopagus twins.
At this time, Tatiana suffered from a sleep apnea condition which occasionally caused her to stop breathing for up to 20 seconds. A sleep apnea specialist, Dr. Fred Kozak, performed surgery on Tatiana and was able to successfully treat her sleep apnea. Not long after the surgery, Tatiana's heart shrank to a more normal size and her heart rate dropped such that it no longer carried all of the burden of circulating blood for both brains.
The documentary reports that Tatiana and Krista are progressing well, and have achieved all the normal childhood milestones, such as walking, talking, and counting.

Famous quotes containing the words progression and/or childhood:
“Measured by any standard known to science—by horse-power, calories, volts, mass in any shape,—the tension and vibration and volume and so-called progression of society were full a thousand times greater in 1900 than in 1800;Mthe force had doubled ten times over, and the speed, when measured by electrical standards as in telegraphy, approached infinity, and had annihilated both space and time. No law of material movement applied to it.”
—Henry Brooks Adams (1838–1918)
“Why are all these dolls falling out of the sky?
Was there a father?
Or have the planets cut holes in their nets
and let our childhood out,
or are we the dolls themselves,
born but never fed?”
—Anne Sexton (1928–1974)
