In the past four weeks, researchers have released results from three important new studies on how exercises found in BrainHQ can have a positive impact on people’s lives. A study published in late June found BrainHQ exercises helped people who had persistent cognitive issues following stays at hospital intensive care units. A study published in early July found a BrainHQ exercise improved processing speed in older adults (average age 81), whether in independent or assisted living. A study with preliminary results announced at an Alzheimer’s conference last week found a BrainHQ exercise increased levels of a key chemical – acetylcholine – which usually decreases with aging and dramatically decreases with dementia. All these studies produced “first ever” results, and add to a rapidly growing body of evidence on BrainHQ, which now includes 150+ peer-reviewed articles. We are committed to providing the best brain training on the planet, and are grateful to the 100s of university-based scientists who keep pushing our scientific understanding forward. |

| | Do You Have Insomnia? Participate in a Study! We are looking for healthy people at least 55 years of age for a study on cognitive training in people with insomnia—specifically, a sleep problem that causes distress or impairment in functioning (e.g., social, occupational). This study is a remote study; no travel is required in order to participate. The cognitive training will last eight weeks and is done on the web. You will also be asked to complete questionnaires and assessments before your training, after your training, and six months after completing your last training session. If you complete everything, you will be paid $80 in electronic Amazon gift cards. Interested? Email sleep@brainhq.com to contact our research staff. |

Too Much Heat Can Muddle Your Brain It’s been a hot July in a lot of the Northern Hemisphere! Research shows that when it’s too hot, the brain slows down. For instance, one recent study showed that students without air conditioning performed 13% worse on a set of cognitive tests than students with air conditioning. This finding is mirrored in other studies. Learn more. |

Priming the Brain for Fatherhood In about 10% of mammal species, dads provide regular paternal care to their young. What makes those species different from the rest? Recent research shows that their brains undergo similar changes as the mother’s—making less testosterone and more estrogen, for example—during the mother’s pregnancy and when the baby is born. And it’s not just mammals—similar hormones are at play for animals like the clownfish, too. Learn more. |

Changing Standards in the Brain Recent research took a look into a strange quirk: that even as certain things become rarer, we tend to see it just as often. Take threats, for example. If the number of threats facing a person goes down, that person will often change what they define as threatening, including things that didn’t seem threatening before. It turns out that the brain compares the threats to what it has seen recently—not some absolute definition of a “threat”—in part because it takes less cognitive effort. Learn more. |

Saying No to Authority Most people are surprisingly bad at standing up to authority, even when they have a moral conflict. In one recent study, for example, researchers asked people to shock other people 60 times. When offered money, most people refused to consistently shock someone else. But when they were told they had to by the research leaders, almost everyone did. Find out what’s going on in the brain in a situation like this. |

Does a Bad Mood Improve Your Thinking Skills? A recent study found that for some people (but not others), being in a bad mood actually improves the ability to organize and complete tasks. It depends on whether you are “high reactive” or not. Find out more. |

Book of the Month: The Performance Cortex: How Neuroscience Is Redefining Athletic Genius (2018) By Zach Schonbrun Have you ever watched an elite athlete and thought, “how do they DO that?” In The Performance Cortex, Zach Schonbrun explains how it’s not just the conditioning of the body, but also the brain, that makes it possible. He takes a look at the neuroscience of athletic prowess, in great athletes today and as a training tool to shape the next generation. Learn more or buy on Amazon. |
