В The diversity of these neurons and vast interconnections facilitate processes such as those involved in decision making, evoking a memory, riding a bike, or simply reading this sentence. В Incorrect wiring of these neurons may be the basis of some mental disorders and deficits. В To understand how the structure of neural networks mediates function, researchers have emphasized the development of techniques to identify how every neuron is intimately connected to its neighbor neurons. В And with this, the field of connectomics is born. Connectomics is considered a branch of biotechnology that uses automated, high- speed imaging systems to construct detailed maps of neural circuits. В This research effort is often compared to genomics, which is well known for the human genome project.
В As the human genome project sought to map and identify all of the genes in human DNA, connectomics seeks to identify and map all neural connections in the brain. В In this respect, a detailed map of neural connections is referred to as a connectome.
In a particular approach to connectomics led by Jeff Lichtman’s lab at Harvard University, a small block of brain tissue is preserved in plastic, sliced into 3. В Approximately 1. В Next, the sections are imaged with an electron microscope at 5 nanometer/pixel resolution. В Imaging a cubic millimeter of brain tissue requires one petabyte of storage space (1. В With the current technology, it would take about 1.
В As a comparison, this is roughly the same amount of data that has ever been created on the entire Internet! Fortunately, we don’t have to wait 1. В Examination of a partially reconstructed 1. TB dataset acquired over 1.
В Within a fully reconstructed 6. В В Watch this TED talk in which Jeff Lichtman shows us what connectomics data actually looks like (begin watching at minute 1. Datasets with this level of detail have previously been considered too numerically complex to acquire and process. В The advancements made in the field of connectomics are making this type of information a reality. В Bottlenecks do still exist in the process flow, but technological advancements are steadily minimizing these impediments. В For example, current image acquisition speeds run at about 1.
TB per day, but researchers project that in a few years, acquisition speeds will reach 3. TB per hour; a 7. В As the catalogue of these datasets expands and encompasses more brain conditions, we may better understand how neurons form circuits to facilitate riding bikes, recalling memories, and gain further insights into the development of neural diseases.~Written by Steven Walston~References: Grantz J.
