Out of Mind in a Matter of Seconds: Surprising Rate at Which Neuronal Networks in Cerebral Cortex Delete Sensory Information

The dynamics behind signal transmission in the brain are extremely chaotic. This conclusion has been reached by scientists from the Max Planck Institute for Dynamics and Self-Organization at the University of Göttingen and the Bernstein Center for Computational Neuroscience Göttingen. In addition, the Göttingen-based researchers calculated, for the first time, how quickly information stored in the activity patterns of the cerebral cortex neurons is discarded. At one bit per active neuron per second, the speed at which this information is forgotten is surprisingly high.

To Say Before Going to Sleep by Rilke

To Say Before Going to Sleep by Rilke I would like to sing someone to sleep, to sit beside someone and be there. I would like to rock you and sing softly and go with you to and from sleep. I would like to be the one in the house who knew: The night was cold. And I would like to listen in and listen out into you, into the world, into the woods. The clocks shout to one another striking, and one sees to the bottom of time. And down below one last, strange man walks by and rouses a strange dog. And after that comes silence. I have laid my eyes upon you wide; and they hold you gently and let you go when something stirs in the dark. (from The Book of Images, translated by Edward Snow in 1991)
