To understand why this is so important for in vivo two-photon imaging, let’s review how 2-p imaging works. Light from a laser is focused to a point and swept across the field in a raster. The resulting fluorescence is of a different wavelength and can thus be filtered out from the excitation light. For each voxel, all the ...

The method uses functional MRI (fMRI) and diffusion tensor magnetic resonance imaging (DTI) to scan the brain, and data crunching software to interpret the data. The researchers hope that the finding will help parents and therapists uniquely identify which learning tools are best for each child. From the announcement by Vanderbilt University : The 45 children who took part in the study ranged in age from 11 to 14 years old. Each child first took a battery of tests to determine their reading abilities. Based on these tests, the researchers classified 25 children as having dyslexia, which means that they exhibited significant difficulty le...

In celebration of Martin Luther King, Jr.: I have a dream that one day I won’t hold my breath every time I tell a person that I suffer from bipolar disorder, that I won’t feel shameful in confessing my mental illness. I have a dream that people won’t feel the need to applaud me for my courage on writing and speaking publicly about my disease, because the diagnosis of depression and bipolar disorder would be understood no differently than that of diabetes, arthritis, or dementia. I have a dream that the research into genetics of mood disorders will continue to pinpoint specific genes that may predispose individuals and families to depression and bipolar disord...

On weekends, we often went to the movies at Universal CityWalk, a replication of Los Angeles within Los Angeles. Why people couldn’t just walk down the real streets of Los Angeles made no sense to me, yet there we were, on a Friday evening, eating ice cream and strolling down a simulated street. We had just seen Total Recall, Arnold Schwarzenegger’s new sciencefiction film about a construction worker who undergoes a false memory transplant that takes him on an imaginary trip to Mars. But...

Even with perfect knowledge of the firing patterns of every cell in a circuit, our understanding of how these patterns are produced and how the information is processed would be quite limited.  True understanding requires knowledge of the precise wiring diagram.  This prize is a good first step towards bringing awareness of this tricky problem to the world’s best computer scientists. $75,000 in prize money was to go to the group that was able to produce high-quality reconstructions of neuronal structures at least 20x faster than by-hand reconstructions.  In the finals...

I think that perhaps the 5 scientists who thought they might learn something about the brain and attention by taking a little camping trip could have figured this out by revisiting Thoreau’s writings: I come home to my solitary woodland walk as the homesick go home. I thus dispose of the superfluous and see things as they are, grand and beautiful. I have told many that I walk every day about half the daylight, but I think they do not believe it. I wish to get the Concord, the Massachusetts, the America, out of my head and be sane a part of every day. - Henry David Thoreau, Journal Even 150 years ago, Thoreau was writing about the...

Or it may be that you are low on acetylcholine.” Acetylcholine (ACh) is a major modulator of brain activity in vivo and its release strongly influences attention. If we could visualize when and where ACh is released, we could more fully understand the large trial to trial variance found in many in vivo recordings of spike activity, and perhaps correlate that to attentional and behavioral states mediated by ACh transmission. Back in grad school, when I was desperately trying to figure out what biological question to answer with my GluSnFR glutamate sensor, I ended up in a meeting with Kleinfeld, his grad student Lee Schroder and Palmer Taylor. We plotted a strategy to make a FRET...

The vasculature was labeled by injecting flourescein dextran into the circulatory stream. The light source was a regenerative amplifier. ‘‘0 mm’’ corresponds to the top of the brain.

I discussed this with Dr. Smith yesterday and she reminded me, once more, that severe depression can’t be treated in a mind-over-matter way. Her compassionate logic made me review the pages of my forthcoming book, Beyond Blue, where I list the neurological and scientific reasons why. And I breathed a much-needed sigh of relief. You deserve one too. Here’s my passage: Trying too hard was precisely my problem. It was the mind over matter issue again. In my mind, I was failing because I couldn’t think myself to perfect...

The name is supposed to look like GFP with a CaM inserted into it, G-CaM-P.  Normally the GFP is dim, as there is a hole from the outside of its barrel into the chromophore.  Upon binding calcium, this hole is plugged and fluorescence increases. The first paper, A genetically encod...

Instead, it joins the growing number of studies that analyze the brain and tell us things like, the structure of the brain may influence ADHD, or that hundreds of gene variations are linked to ADHD, or that, it’s not that people with ADHD’s brains don’t have enough dopamine, it’s that the brain pushes dopamine in the wrong direction influencing a ‘speed’ response between nerve cells. I could go on, but I hope you get the point. Hundreds of studies have now been done analyzing the brains and genes of people with mental illness, but it doesn’t feel like we are any closer to the truth than we were 10 years ago. One of the reasons is because none of these kinds of studies she...

It appears the “news” article is in support of a BBC program airing tonight called, Bang Goes the Theory, which is running a brain training “experiment” on its website, the Brain Test Britain experiment. Ironically, the experiment designed for the web has four of the five problems listed below! I guess nobody who designed the experiment talked to Dr. Owen first. Oops.

Synaptic Mechanisms for Plasticity in Neocortex Daniel E. Feldman Sensory experience and learning alter sensory representations in cerebral cortex. The synaptic mechanisms underlying sensory cortical plasticity have long been sought. Recent work indicates that long-term cortical plasticity is a complex, multicomponent process involving multiple synaptic and cellular mechanisms. Sensory use, disuse, and training drive long-term potentiation and depression (LTP and LTD), homeostatic synaptic plasticity and plasticity of intrinsic excitabilit...

The second pushes super-resolution imaging into fast, live-cell imaging.  The third, by a friend from graduate school, uses G-CaMP to make strong claims about olfactory coding in fruit flies. The last reports remarkable data pointing to the distributed nature of conscious perception in humans, which would have been a great data set to reference in my recent talk on free will.

Instead of bland studies that describe psychological processes in 8,000 word articles, brain imaging allows for pretty, compelling pictures of the brain (as we noted in a blog entry over a year ago). But the pictures may not be telling us what we think. A new study by Edward Vul in press in Perspectives on Psychological Science suggests that the validity of many studies that use brain imaging techniques — such as functional magnetic resonance imaging (fMRI) — may be in question: In those studies, researchers used fMRI to measure blood oxygenation — a marker of neuronal activity — in specific brain regions during behavioral tasks. As is typical in fMRI studies, research...

How can we identify the group of neurons that encode a particular thought?   I don’t want to simply see correlations of in activity of a few scattered neurons with a given thought, but identify the entire neuronal ensemble.  Which neurons are active at a precise moment in a task?  How are they wired together?

Many techniques require the novice to be taught the technique from a more experienced colleage. Unfortunately, it is not always easy to find someone skilled to be trained from.  Labs which pioneer the techniques have only a limited amount of time and resources available to train outside scientists. How can advanced scientific skills be distributed more broadly and efficiently? A good place to start is the Journal of Visualized ...

One strategy for understanding what processing takes place is to record the patterns of brain activity while showing many patterns of input, then see if you can use the information gained to predict a novel input, given the pattern of brain activity. The canonical example of this approach is visual input reconstruction based on recorded spike trains in the visual system of the blowfly. The blowfly is a relatively simple system (though quite efficient) with a tiny brain. Could a similar approach work in humans?  Although we can’t drop electrodes into the visual cortex (usually), we can put people in fMRI scanners to visualize the pattern of blood oxygenation, which is correlated with neural acti...

Binary-contrast, 10 10-patch images (2100 possible states) were accurately reconstructed without any image prior on a single trial or volume basis by measuring brain activity only for several hundred random images. Reconstruction was also used to identify the presented image among millions of candidates. The results suggest that our approach provides an effective means to read out complex perceptual states from brain activity while discovering information representation in multivoxel patterns.        (Source: Brain Win...

We have been witnesses and fortunate end-users to this web evolutionary development. From our street corner, we have observed a waterfall of resource and journal sites free of charge open shop like market day. As I started exploring Medicine 2.0, I blogged about 2 sources, WorldVista and PLoS Biology. Let me share more about them here again in a short while. First, here is something close to the heart, an open journal site that presents experiments in video format. JoVE. Journal of Visualized Experiments (JoVE) is a peer reviewed, open access, online journal devoted to the publication of biological research in a video format. For a sample, view this experiment on “A Cranioto... the story of healing blogs http://www.medworm.com/rss/comments.php?id=1263426 Thu, 28 Feb 2008 00:15:46 +0100 1263426 http://www.medworm.com/index.php?rid=823089&cid=t_142924_109_f&fid=35677&url=http%3A%2F%2Ffeeds.feedburner.com%2F%7Er%2FBrainBasedBusiness%2F%7E3%2F148481097%2Fmind_over_matter_gets_techie_l.html We’ve all worked with people who defy the odds with more than human strength, willpower or determination.

His firm teaches people to think away pain, addictions, depression and other negative mental conditions. Omneuron promotes a brain-scanning technology called real-time functional magnetic resonance imaging, or fMRI. Scanners measure blood flow to different parts of the brain, t...
