Hitachi have demonstrated a brain-machine interface allowing users to perform simple switching. “In the experiments, test subjects were able to activate the power switch of a model train by performing mental arithmetic and reciting items from memory.” [source: Pink Tentacle] Continue reading

Puramatrix Bring Nano-Scaffolding to Market

The Foresight Nanotech Institute have published glowing praise for the aspirations of PuramatrixTM founder, Prof. Shuguang Zhang. They approvingly quote Zhang from an eJournal article:

For example, aging and damaged tissues can be replaced with the scaffolds that stimulate cells to repair body parts or to rejuvenate the skin. We also might be able to swim and dive like dolphins or to climb mountains with a nanoscaffold lung device that can carry an extra supply of oxygen. It is not impossible to anticipate painting cars and houses with photosynthesis molecular machines that can harness the unlimited solar energy for all populations on every corner of the planet, not just for the wealthy few…[source]

The Puramatrix company website has an impressive publications list. The company is basing its business on nano-scaffolding techniques that can be used to facilitate the construction of any number of other structures and mechanisms.

Another old piece of research. Cat vision being decoded at Berkeley by Yang Dan, Garrett B. Stanley and Fei Fei Li:

Decoded cat vision and source

The original research was reported in:

Garrett B. Stanley, Fei F. Li, and Yang Dan
Reconstruction of Natural Scenes from Ensemble Responses in the Lateral Geniculate Nucleus
J. Neurosci., Sep 1999; 19: 8036 – 8042

The abstract, links to full text and citations can be found at The Journal of Neuroscience.



Neural Prostheses

I am reminded by the Memory and Database blog to keep up with some old references. Theodore Berger of the USC Department of Biomedical Engineering was much mentioned in 2003 when he announced plans for a research programme studying technological memory augmentations. New Scientist article, World’s first brain prosthesis revealed from 2003 here.

Bergman, with Dennis L. Glanzman, has edited a collection of papers entitled, Towards Replacement Parts for the Brain. Implantable Biomimetic Electronics as Neural Prostheses (2005: MIT Press ). See the MIT Press website for the contents and sample chapters. Only available as hardback I’m afraid. For everyone considering a career change one interesting discussion addresses the the contents of syllabi for courses on neural engineering.
