University of Washington (Washington, USA) researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher. Using electrical brain recordings and a form of magnetic stimulation, Professor Rajesh Rao sent a brain signal to researcher Andrea Stocco who was on the other side of the university campus, causing Stocco’s finger to move on a keyboard. The technologies used by the researchers for recording and stimulating the brain are both well-known. Electroencephalography, or EEG, is routinely used by clinicians and researchers to record brain activity noninvasively from the scalp. Transcranial magnetic stimulation is a noninvasive way of delivering stimulation to the brain to elicit a response. Its effect depends on where the coil is placed; in this case, it was placed directly over the brain region that controls a person’s right hand. By activating these neurons, the stimulation convinced the brain that it needed to move the right hand. While researchers at Duke University have demonstrated brain-to-brain communication between two rats, and Harvard researchers have demonstrated it between a human and a rat, this is considered to be the first successful demonstration of human-to-human brain interfacing.

Tip #192 - Stay Connected
Researchers from the University of Chicago (Illinois, USA) report that social isolation may be detrimental to both mental and physical health. The team analyzed data from the National Social Life, Health, and Aging Project, a nationwide US study involving 3,000 men and women, ages 57 to 85 years. They arrived at three key findings regarding the relationships between health and different types of isolation:
• The researchers found that the most socially connected older adults are three times as likely to report very good or excellent health compared to those who are least connected, regardless of whether they feel isolated.
• The team found that older adults who feel least isolated are five times as likely to report very good or excellent health as those who feel most isolated, regardless of their actual level of social connectedness.
• They determined that social disconnectedness is not related to mental health unless it brings feelings of loneliness and isolation.
Separately, Rush University Medical Center (Illinois, USA) researchers studied 906 older men and women, testing their motor functions (including grip, pinch strength, balance, and walking) and surveying their social activity, for a period of 5 years. Those study participants with less social activity were found to have a more rapid rate of motor function decline. Specifically, the team found that every one-point decrease in social activity corresponded to an increase in functional aging of 5 years, translating to a 40% higher risk of death and 65% higher risk of disability.
