Cells can grow on silicon: Researchers at the University of Calgary have found that nerve cells grown on a microchip can learn and memorize information which can be communicated to the brain.
“We discovered that when we used the chip to stimulate the neurons, their synaptic strength was enhanced,” said Naweed Syed, a neurobiologist at the University of Calgary's faculty of medicine.
The nerve cells also exhibited memory traces that were successfully read by the chip, said Syed, co-author of the landmark study published in February's edition of Physical Review Letters, an international journal.
