Mind reading - with electrodes

Sagittal view of human brain

BBC News science and technology reporter Jason Palmer tells about something that on first hearing sounds totally impossible: "Researchers have demonstrated a striking method to reconstruct words, based on the brain waves of patients thinking of those words." (BBC)

Reconstructing Speech from Human Auditory Cortex
"The technique reported in PLoS Biology relies on gathering electrical signals directly from patients' brains.

Based on signals from listening patients, a computer model was used to reconstruct the sounds of words that patients were thinking of. The method may in future help comatose and locked-in patients communicate.

Several approaches have in recent years suggested that scientists are closing in on methods to tap into our very thoughts; the current study achieved its result by implanting electrodes directly into a part of participants' brains. BBC

Humanity using its brains to learn about brains
The Bible does not talk about human or animal brains. We can understand this since neither in the Ancient Near East nor in the classical Greek and Roman periods was there any understanding of the significance of that greyish whitish thing that could be seen inside human and animal heads.

The physical understanding of brain functions requires some knowledge about a thing we call electricity.
But only the rise of computers, neural networks and understanding of how nerve systems work has given us a grasp of what is going on in the brains of living creatures.

I think that it is rightly said that BRAIN IS THE LAST FRONTIER OF HUMAN SCIENCE

and what a frontier!
