Hi!
This is Andreas, the Norwegian MD/PhD in neuroscience candidate who worked as an intern at SharpBrains a few months ago. Now I’m back in chilly Oslo where I’ve just begun my PhD program on cognitive training for patients with memory problems.

Today I felt it was time to reflect upon my 3 month stay in San Francisco earlier this year. It all started when in April when the Norwegian school of entrepreneurship said: You’ve got a ticket to San Francisco, now you got to find the perfect start-up company to work for.

Being interested in brain training, I googled “Brain fitness San Francisco” and guess what I found? I got in touch with Alvaro Fernandez, the co-founder of SharpBrains.com and two months later I started working with him and his team.

As a scientist, being placed in an exciting start-up company in a novel market like brain fitness was a huge learning experience that gave me hands-on knowledge of business and entrepreneurial culture. Being a neuroscience student, I know that learning physically changes my brain, strengthening it.

Here’s a list of some of the key things I’ve learned:

1) First of all, one of key rules for brain fitness is learning. In SharpBrains I immediately got to experience what a great learning culture can be all about – from key insights in entrepreneurship to how to make creative videos and writing for the web. The urge for constant learning is both fun and stimulating – and I appreciate Alvaro’s suggestion to write this post.

Party For Polyglots

Difficulty: MEDIUM
Type: LOGIC

Question:
Of the 100 people at a recent party, 90 spoke Spanish, 80 spoke Italian, and 75 spoke Mandarin. At least how many spoke all three languages?

Have you solved it yet? If you are working the problem, making hypotheses, testing your ideas, and coming up with a solution, you are using your frontal lobes. This is great exercise because the frontal lobes follow the “last hired, first fired” adage. They are they last areas of your brain to develop and the first to suffer the ravages of time and stress. So, keep exercising! Just like your voluntary muscles, regular brain workouts will help you keep more active neuronal circuits in your brain which helps you function better today, as well as create a protective barrier against aging.

Let us know what you think of the puzzle and please welcome Wes!

Well, the idea that you can just pop a pill to improve your memory and attention lost some ground today.

The Associated Press released an article on DHEA, a steroid precursor to testosterone and estrogen used to improve athletic performance, increase sex drive, and reduce fat as well as fight diabetes and heart disease. The conclusion of a two-year study at the Mayo Clinic in Minnesota and University of Padua in Italy was that it did not improve strength, physical performance, or other measures of health. The positive news was: Read the rest of this entry »
