New Mathematical Model Suggests How The Brain Might Stay In Balance Oct 5, 2009
Magnasco s model differs from traditional models of neural networks, which assume that each time a neuron fires and stimulates an adjoining neuron, the strength of the connection between the two increases ... This model of a balanced neural network is abstract it does not try to recreate any specific neural function such as learning ... The other half of the network could be used for other functions that may be compatible with more traditional models of neural networks, including Hebbian... (Science Daily)
Book says Ted Williams' Head Abused Oct 3, 2009
Lets suppose for a Planck time unit, that the neural network that comprises the brain functions could somehow be brought back online, and those impulses that ultimately became William's consciousness could be re-created, even though they have never been recorded or preserved in the first place. There then is no need, or point to try to download it into a mass of dead cells, Williams' self awareness could then exist in a computer, still no need for the head to be preserved. (CBS News)

Researchers see evidence of memory in the songbird brain Jun 28, 2009
"Whenever something unexpected and different comes along, such as the song of a new bird in the neighborhood, it's going to deform the listening bird's neural network," Clayton said. "And so the system has to basically absorb some of that, make some changes and not be overwhelmed by it. If you push the system around too much, cells die.". (EurekAlert!)
Pitt melanoma researchers present novel findings at ASCO May 31, 2009
