new brain chip can connect to thousands of neurons, send signals back to hundreds

One small step towards mind control and cyborgs.
The mobile chip maker Infineon, working with a team from Italy and Germany, has developed a chip that can read signals from up to 16,328 mammalian brain cells, and send signals back to several hundred of them. The scientists tested the chip on snails, due to the simplicity of the cells, and tinkered with the genetics of the organisms to get the combination to work even better. In order to get neurons to attach to the circuit, the researchers had to develop a "neural glue" using a protein from the brain which glues connections together and also attracts sodium pores.
