These are important problems to solve because much larger datasets of this type will soon be available as part of the connectomics initiative to map entire brains at synapse resolution.

It’s expected to be a novel way to empower search engines for visual images … and should be available this summer.According to the  University of Ottawa graduate student,  Kris Woodbeck,  Canadian government officials at Technology Transfer and Business Enterprise (TTBE)  will help him secure a patent on his innovative computer search approach.The invention earned Woodbeck the university’s Innovator of the Year award last week. His search engine copies the brain’s approaches to process visual information.  How does it work? “The brain is very parallel. There’s lots of things going on at once,” he said. “Graphics pro...

Though a bit skimpy on functionality compared to the heavy-weight Flash viewers, it is snappy fast, uses very little memory, and in principle, allows for better integration with other HTML entities through DOM. An example is at http://brainmaps.org/ajax-viewer.php?datid=95&sname=123What's more, the multiresolution viewer has been released as the Brain Maps API. The following is from the Brain Maps API page at http://brainmaps.org/index.php?p=brain-maps-api:"The Brain Maps API lets you embed Brain Maps in your own web pages with JavaScript.

In line with this, one of the developers at BrainMaps.org, Issac Trotts, has released a veritable Google Earth for the Brain, called StackVis. In a nutshell, StackVis is a 3D viewer of neuroanatomical sections. But it is revolutionary in the sense that it permits rapid interactive viewing of arbitrarily large images. Conventional microscopy, electron microscopy, and imaging techniques such as MRI and PET commonly generate large stacks of images of the sectioned brain. In other domains, such as neurophysiology, variables such as space or time are also varied along a stack a...

And specifically, I wanted to see the distribution of AChE in 3D. This data is available online (for the mouse brain) at both the Allen Brain Atlas and BrainMaps.org, so I went to both sites to see the AChE distribution in 3D. Here I was veritably shocked by the comparison. First, let's look at the Allen Brain Atlas 3D file for AChE, which is the big yellow amorphous blob shown on the rightThen I went to BrainMaps.org and obtained the 3D file for the AChE distribution in the mouse brain, and this is what it looks like in the figure to the right. Note that in both of these figures, the viewpoint is oblique lateral, with anterior pointing to th...

Welcome to StackVis, a 3D viewer of neuroanatomical sections.Figure Caption. The development of additional desktop application tools for interacting with brainmaps.org image and database data includes the one shown here, StackVis, which is a 3D viewer of neuroanatomical virtual slide image stacks that is integrated with high resolution viewing of and interaction with individual sections comprising the image stack. (A) horizontal image stack of nissls of the macaque brain viewed from below. (B) same image stack as in (A) but from a different perspective, with increased inter-section spacing, and with areal and nuclear labels. (C) coronal image stack of nissls of the mouse brain.

This allows independent viewing of images by large numbers of people in diverse locations.Prior to recent advances in virtual microscopy, slides were commonly digitized by various forms of film scanner and image resolutions rarely exceeded 5000 dpi. Nowadays, it is possible to achieve more than 100,000 dpi and thus resolutions approaching that visible under the optical microscope. This increase in scanning resolution comes at a price; whereas a typical flatbed or film scanner ranges in cost from $200 to $600, a 100,000 dpi slide scanner will range from $80,000 to $200,000.Virtual microscopy has been characterized as potentially a disruptive technology. A disruptive technology is a...

We are now beginning to witness similar digital mapping technologies spilling over into other non-related fields, one of the more interesting of which is neuroscience and the collaborative digital mapping of the brain.Launched less than a year ago, BrainMaps.org has rapidly developed to lead the field in digital brain mapping technologies. With several terabytes of ultra high-resolution brain image data, consisting of several dozen mouse, monkey, and human brains, its online brain image database is the largest and most diverse currently available. This massive image data is integrated with structural information regar... BrainTechSci blogs http://www.medworm.com/rss/comments.php?id=471535 Mon, 17 Apr 2006 00:57:00 +0100 471535
