China Develops Robots to Implant Chips into Human Brain

A Chinese technology news website reported that the CyberSense flexible microelectrode implantation robot, developed by the Institute of Automation at the Chinese Academy of Sciences, has passed the preliminary acceptance stage for Shenzhen’s major scientific infrastructure project on “Brain Mapping and Brain Simulation.” The robot is designed to implant flexible microelectrodes – thinner and softer than a strand of hair – into the cerebral cortex of experimental animals, providing crucial support for brain-computer interface (BCI) and neuroscience research.

Brain Mechanisms and Constructed Languages vs. Natural Languages

"Constructed Languages Are Processed by the Same Brain Mechanisms as Natural Languages." Malik-Moraleda, Saima, et al. Proceedings of the National Academy of Sciences 122, no. 12 (March 17, 2025): e2313473122.

Significance

What constitutes a language has been of interest to diverse disciplines—from philosophy and linguistics to psychology, anthropology, and sociology. An empirical approach is to test whether the system in question recruits the brain system that processes natural languages. Despite their similarity to natural languages, math and programming languages recruit a distinct brain system. Using fMRI, we test brain responses to constructed languages (conlangs)—which share features with both natural languages and programming languages—and find that they are processed by the same brain network as natural languages. Thus, an ability for a symbolic system to express diverse meanings about the world—but not the recency, manner, and purpose of its creation, or a large user base—is a defining characteristic of a language.

The origin of human language: cognition and communication

We touched upon this question recently in "Chicken or egg; grammar or language" (1/15/25), where we examined Daniel Everett's thesis as propounded in How Language Began:  The Story of Humanity's Greatest Invention.  In that volume, Everett argues that language is learned / acquired / developed, not hard-wired in the human brain.  He holds that our ancient ancestors, Homo erectus, had the biological and mental equipment for speech 1,500,000 years ago, 10 times earlier than the conventional wisdom that language originated with Homo sapiens 150,000 years ago, and that it was the result of a "language instinct". 

Now we come back to the lower date with this new research as presented in:

Shigeru Miyagawa, Rob DeSalle, Vitor Augusto Nóbrega, Remo Nitschke, Mercedes Okumura, Ian Tattersall. Linguistic capacity was present in the Homo sapiens population 135 thousand years ago. Frontiers in Psychology, 2025; 16 DOI: 10.3389/fpsyg.2025.1503900
