A recent conference discussed whether neurons could have evolved twice on Earth. Neurons in the nervous systems of comb jelly fish are argued to be sufficiently unlike other neurons in nature, to suggest that neurons may have evolved multiple times. If neurons evolved more than once on Earth, there is a greater likelihood that they could evolve elsewhere in the universe.

Towards a neural stance on consciousness :: Victor Lamme, University of Amsterdam :: Trends in Cognitive Science, Vol. 10, No. 11, 25 September 2006 :: www.cell.com/trends/cognitive-sciences/home Summary and review of the above article Lamme says that he wishes to approach the question of consciousness from the direction of neuroscience. He asks why it is that some neural processes produce conscious experience, but others do not. Certain distinctions between conscious and unconscious processing Read more […]
Single cell organisms and neurons Based on Michael Marshall, New Scientist, 3 September 2011, referring to work by Dirk Fasshauer, Xinjiang Cai and Harold Zakon Important components of neurons are shown to be already apparent in early single-cell organisms. Dirk Fasshauer et al, University of Lausanne have found the important neural proteins, Munc18 and syntaxin1 in simple single-cell aquatic organisms called choanoflagellates. The interaction between the two proteins in these organisms was Read more […]
Neurons and logic gates from the webmaster The idea that the brain is a computer has been popular since the invention of the latter, and this remains a mainstream consensus. The feeling of many others that there is an essential difference between computers and humans has tended to be pushed aside as an uneducated delusion. However, although much brain processing can be accepted as being analagous to computing, it may be that there is a fairly easy to detect structural difference between Read more […]
