Day #67: On being a student coordinator

wiring

Look at my beautiful wiring job!!!!

I figure we can finish out the week by talking about yet another project that doesn’t involve my research. I’m a student chair for a workshop for neurotech entrepreneurs. Fun fact: I’ve never done this before. Yep, there has to be a first time for everything you do and this will be my first time attempting to run one of these things. Let’s talk about what that looks like. (more…)


Day #66: Sometimes we learn more from failure

BrokenLaser1

Not everything can be safely laser cut…

It has been a busy week, as you’ve seen I’ve had not one, but two Skype a scientist sessions in one day, then we did some outreach with some local 4th graders, yesterday I even posted photos of the event. Yesterday I also had a conference call to help set up an event that I’m helping run for neurotech entrepreneurs. If you follow me on twitter, you know I’ve pushed people to apply for it. So let’s talk about what I’ve got going on today!

Day #65: Lab Tour photos

As you may have seen, yesterday we had our lab tour group come through. So today I just wanted to share a few photos from the time they had with us, it was a lot of fun and hopefully we inspired a few kids!

Day #64: Lab Tours!

Just hanging out with some exoskeleton friends.

When doing your advanced degrees (Masters or PhD) you end up with a lot of different responsibilities that have nothing to do with your education. That isn’t to say that it isn’t an important thing or that I hate doing it, you just don’t learn anything with regard to your study subject. Today is one of those days, let’s talk about it.

Day #63: The Importance of Science Outreach

skype a scientist

Today is Skype a Scientist day! Every term I volunteer my time and try to explain my journey, my research, and my pitfalls with students all over the US. Technically this is my second session (of six!) this term, but I wanted to talk about why I do what I do today. So if you’re interested in what it’s all about, keep reading.

Day #7 : Small waves, or wavelets! – 365 DoA

Meyer Mother wavelet

This is the Meyer wave, a representation of a so-called mother wavelet function to use for the wavelet transform. Notice that it is finite!

Waves! We’re officially one week through 365 Days of Academia! Woo! 1 week down, 51(.142…) weeks left! Let’s wrap up this weeks theme (there wasn’t originally a theme, but it kind of ended up that way) by talking about other ways we can get to the frequency domain. Specifically, let’s stop the wave puns and let’s talk wavelets!*

Erasing unpleasant memories with a genetic switch

erasing memories

Researchers have managed to erase unpleasant memories in mice using a ‘genetic switch’.  Dementia, accidents, or traumatic events can make us lose the memories formed before the injury or the onset of the disease. Researchers have now shown that some memories can also be erased when one particular gene is switched off.

Neuroscientists discover new learning rule for pattern completion

Recently, scientists discovered a new learning rule for a specific type of excitatory synaptic connection in the hippocampus. These synapses are located in the so-called CA3 region of the hippocampus, which plays a critical role for storage and recall of spatial information in the brain. One of its hallmark properties is that memory recall can even be triggered by incomplete cues. This enables the network to complete neuronal activity patterns, a phenomenon termed pattern completion.

Forgetting, to learn

rememberable

rememberable

They say that once you’ve learned to ride a bicycle, you never forget how to do it. Unfortunately for students who hope this applies to studying, they might not like new research suggesting that while learning, the brain is actively trying to forget. While this may at first blush seem like a bad thing, it actually may be useful for those suffering from PTSD.

‘Delayed remembering’: Kids can remember tomorrow what they forgot today

'Delayed remembering': Kids can remember tomorrow what they forgot today

For adults, memories tend to fade with time. But a new study has shown that there are circumstances under which the opposite is true for small children: they can remember a piece of information better days later than they can on the day they first learned it. While playing a video game that asked them to remember associations between objects, 4- and 5-year-olds who re-played the game after a two-day delay scored more than 20 percent higher than kids who re-played it later the same day.
