Science: Exercise activates neural rhythms tied to learning and recall

A recent research study indicates that a single exercise session activates neural rhythms tied to learning and recall. By directly recording brain activity, this study shows for the first time in humans, that even a single bout of exercise can rapidly alter the neural rhythms and brain networks involved in memory and cognitive function.

Previously, neuroscientists had documented brain activity (ripples) relevant to memory in mice and rats, but they had not confirmed the link in humans. That's mainly because electrodes need to be implanted in the brain to obtain recordings. Instead, researchers had theorized the ripples' role in humans, based on studies in people that measured changes in oxygenated blood in the brain after exercise. This is first time researchers have visualized the corresponding neural activity in brains after exercise.



Also, a higher heart rate during exercise, which reflects higher exercise intensity, was related to a subsequent increase in resting state brain activity across cortical networks related to memory formation.

Caution: Since this study was small (n = 14) and the participants varied in their clinical condition, this needs to be replicated with more subjects to confirm these findings.

The MonoRacer 130E Fully Enclosed Motorcycle Aims to Redefine Personal Mobility

The MonoRacer 130E Fully Enclosed Motorcycle Aims to Redefine Personal Mobility Elena Gorgan The idea of making something that would be halfway between a bicycle or motorcycle and a car is not new; after all, the advantages of such a vehicle would be many for a large segment of the market. In the Czech Republic, inventor, fabricator and full-time pilot Arnold Wagner has been making one such vehicle since the late ‘80s. Since 2009, with a new partner, he launched the  PERAVES CZ  company, and they’ve been putting out these cabin-motorcycles dubbed MonoRacer since then. They probably haven’t sold more than a couple of hundred of them (90 of which were made before the 2009 partnership), but that could change as early as this month. As it turns out, PERAVES CZ has made an electric version of the MonoRacer, called the MonoRacer 130E, and it is now in the process of receiving EU-certification. The MonoRacer 130E is an electric motorcycle with a fully enclosed cabi...

More sad news............

 I really really hope this is on the up and up. With interactions with people on the internet, you can never be sure if what we hear is real. BUT, because we have all been wondering what happened to Susan, I will repost an email I got this morning: Hi, This is Walter, Susan's step son who she mentioned live in California.  I am sorry to inform you that Susan took her life the day before Thanksgiving by locking herself in the garage with the cars running.  I can see from your communications that she trusted you and that is why I am informing you that she committed suicide.  Thank you for encouraging her to trudge along in life if her husband were to die.  I wish she would have listened to you closer.   The email did come from her email address . So, I replied with condolences and thought it best to drop this note to let you all know of her passing. To my authors who have her on their invite list, you can now remove her name.
