The neurons that shaped civilization. Empathy & types of mirror neurons.

"There is no real independent self, aloof from other human beings, inspecting the world, inspecting other people. You are, in fact, connected not just via Facebook and internet, you’re actually quite literally connected by your neurons." — V S Ramachandran

The cosmos is also within us, we're made of star-stuff. We are a way for the cosmos, to know itself.

Cosmos: A Personal Voyage is a thirteen-part television series of one hour shows written by Carl Sagan, Ann Druyan, and Steven Soter, that was aired at the tail end of 1980 and was - at the time - the most widely watched series in the history of American public television. It is best introduced by an audio excerpt of one of his books, The Pale Blue Dot. Inside is a complete annotated collection of the series. [more inside]

Sleep Deprivation Amps Up the Brain

Sleep deprivation making you feel jumpy? It's not in your head. Human cortical excitability increases with time awake. [Abstract and link to full paper.]

I give them 50 years for me.

Functional Neurons Induced From Adult Stem Cells. Meanwhile, stem cells may be better than bone marrow for certain cancers, and have the potential to revolutionize the supply of blood. Anecdotal success stories continue to pile up.

Somewhere, over the brainbow...

Brainbow. Using some very cool genetic tricks, Harvard scientists have found a way to make transgenic mice that express various mixtures of different coloured fluorescent proteins in their neurons. The result, individual brain cells with up to 90 distinct colours. Not surprisingly, this visually impressive work is in this month's issue of Nature.

singularity gets just slightly closer

Italian & German researchers have created a "neuro-chip" for linking computers with mammalian neurons (A NewScientist, LiveScience, MSN). They added neuron gluing proteins to the chip to attract the sodium pores, and genetically modified the neurons to add more sodium pores.

In the short term, the work is expected to aid the pharmaceutical industry in testing the effects of drugs on neurons, assist basic research into the workings of the brain, and perhaps help treat neurological disorders. In the long term, numerous sci-fi technologies are slightly closers, such as computers with living components, useful brain implants, and Beowulf clusters of humans.

Brain Cells Used To Make Working Semiconductor

Brain Cells Used To Make Working Semiconductor "This is the first direct functional interfacing of a living neuronal network with an electronic semiconductor chip," said co-author Dr. Peter Fromherz of the Max Planck Institute for Biochemistry in Munich, Germany, in an interview with Reuters Health. "It is a further step on our road to combine the elements of brains and computers," he added.
