Neuroscientists discover ‘engine of consciousness’ hiding in monkeys’ brains

A team of researchers has found an “engine of consciousness” in the brain — a region where, in monkeys at least, even a little jump start will make them wake up from anesthesia.

Consciousness is a mystery. We don’t know for certain why creatures are sometimes awake and sometimes asleep, or which mechanisms in the brain are most important for a conscious state. In this new paper, though, researchers turned up some important clues. Using electrodes across the brains of awake and sleeping macaques, as well as macaques under different forms of anesthesia, the team found two key pathways in the monkeys‘ brains for consciousness. The researchers also found a specific brain region that seems to get those pathways going, like an engine they could start using some highly specialized jumper cables. That region is known as the central lateral thalamus.

The aye-aye is one of nature’s most fascinatingly bizarre creatures. Native to Madagascar, this lemur is the largest nocturnal primate in the world and has unique features that set it apart. It has bat‐like ears that allow it to echo-locate and rodent-like ever-growing incisors — both unique among primates.

As a new coronavirus spreads in China and around the world, scientists are scrambling to find out exactly where it came from. Now, a new study provides more clues to the virus’ origins, and points to bats as the most likely hosts.

In the study, published today (Jan. 29) in the journal The Lancet, the researchers analyzed 10 genome sequences of the novel coronavirus, dubbed 2019-nCoV, obtained from nine patients in China who were sick with the virus.
