Tool to read faster

I recently came across the website of this company Spritz. They claim to have found a way to scientifically fasten your reading speed.

Here’s how it works. First, they identify the Optimal recognition point (ORP) of a word. Then they highlight that letter with red color (rest of the letters being black). As a reader you fixate around the ORP and they show each word in a text at a certain speed. No macro eye movements are required. So that saves you from the fatigue. And if you keep at it for a while, your reading speed evidently increases. You can go from 130 words/minute to 250 words/minute pretty quickly. In fact, they also pause and introduce gaps at punctuation. I have tried it and it seems to work. It is best for reading books (without images) and news articles. Here’s a snapshot of the app. (iTunes Link; free download, but you have to pay 4$ to really reap its benefits).

In the screen-shot, you can see the ORP in red, the main text (blurred, in the bottom). Each word is shown one by one.

Melanie wins Gold medal at the 57th annual Hudson County Science Fair


I am delighted to share the news that Melanie Arroyave (Bayonne High School), who worked with me for a couple of months last summer (on concurrent transcranial electrical stimulation and fMRI) from the Partner in Science Program ( ), won the gold medal at the 57th annual Hudson County Science Fair. She presented the work that she did with me here at Rutgers. Congrats Melanie!

She is super excited, and wants to come back for this summer too and work in our lab (Krekelberg Lab)! It makes me happy because she is one of the youngest minds we have stimulated and that too without putting any electrodes on it!

Defending my Thesis (video) on Dec 16, 2014

Finally the day has come and gone ..

Strangely, I feel more relieved than happy. Most likely because i am back next day where i have always belonged (the lab space), doing pretty much the same thing and enjoying the ability to think freely again.. But one task off the to-do list! I am attaching the video of my defense talk. This serves the following purposes,

1. My parents can now watch it from India.
2. If you are a dear friend and missed it, here’s your chance to watch it.
3. Future recruiters, who might wanna check me out can do so, without me knowing or having to travel to their home ground to defend myself.

Partners in Science – 2014

This summer I got to interact with and mentor two very nice and smart high school students for the partners in science program. They are not even juniors but they really worked hard and grasped most of the key concepts of my PhD thesis. We worked together to analyse some fMRI data on a very recent (unpublished) experiment. I am putting their presentation video here. Mentoring them has been one great learning opportunity for me too. It has been ultimately a very satisfying experience. I would very much encourage any grad student to try and do this if possible. Not only it is a rewarding experience for us, it is also a great way to make kids interested in real science. Occasionally, I was also reminded how simple questions asked by the students can make you think harder than ever and make you realize that basics are so important.

Computational Neuroscience in Vision @ CSHL: The Epilogue

As time went on, it became tougher to post here. But the course went on in its full force and left us wanting for more. I can say without any doubt that this has been the single most influential 2 weeks of my scientific career so far. Just getting to know so many like minded people, chilling out with them, discussing ideas and listening and learning from their opinions has definitely made me a more complete science enthusiast (if there is something like that). A few crucial lessons i learnt (on the bigger picture) from the course are:

1. Decide if you wanna catch the fly or count the hairs on its legs (#Pascal).
2. We all suffer from impostor syndrome and hence we shouldn’t worry about it (#Weiji)
3. You can perhaps decode which face i showed u from looking at V1 voxels and probably not from FFA voxels, but that doesn’t make V1 a face area or FFA not a face area. So what does decoding really help at deciphering? (#Tony)
3. 10-20% of all grad students will probably make it to being PIs. You are in that group. So just keep working as hard and you’ll get there (#Geoff)
4. Developing sound intuitions about the use of various computational methods are what we can really take home from these meetings (#self)
5. Knowing the right person at the right time is not luck but a result of multiple factors (having real interest in science, publishing papers, attending these kind of summer courses, being genuinely interested in learning from other’s work etc) that maximizes the likelihood of the event!

Computational Neuroscience in Vision @ CSHL: Day 4

Day 4 started off with Geoff’s 2nd lecture on fMRI. After briefly recapitulating the properties of a linear system, he spoke about the use of general linear models in fMRI analysis. He mentioned about ‘m-sequences’. At the end of his talk, Geoff told us that he thinks that vision neuroscientists have been completely focused on peripheral vision and that should change. The afternoon session was taught by Stephanie. This is the first time when the weaponry (nerf guns) were officially employed 🙂 Infact, Stephanie herself asked us to shoot if we didn’t understand any concept or if she went too fast. Although since Jonathan invited her, she gave us the option to shoot at Jonathan instead as well! The pic below summarizes it all….

Stephanie talked about information theory. In the break time we played “the spike lottery” (I will explain it some other day). 

Computational Neuroscience in Vision @ CSHL: Day 3

Another great day as it started with bacon and sausages in breakfast.

Gregg started off the day with a very nice introduction to the white noise analysis of V1 data. The best part of the talk to me was the geometric interpretation of STA. That has been inserted into my “take home” list of ideas or interpretations from the course. Also the way we can estimate the nonlinearity in the LNP model was really explained well by Gregg. He also went over contrast invariance of V1 complex cells and the reason to start looking into STC etc beyond STA.

In the afternoon session, Geoff gave us a hands on tutorial on psychophysics and signal detection theory in MATLAB. At 3 pm, we started watching the world cup game which ended with my disappointment 😦

Dinner was brilliant as always! We met Stephanie (who’s giving a talk tomorrow) at the dinner table and we all had a very philosophical discussion in the dinner table (topics: are computational principles generalizable across species? are lfps epi-phenomena? etc)

Marjena (one of our TA) presented her research after dinner, which was obviously followed up by two rounds of mafia.
