A complete guide to imaging and analyzing spines and neurons with Neurolucida 360


Following a well-designed protocol is essential to achieving accurate and consistent results in scientific research. Now, scientists using Neurolucida 360 for dendritic spine and neuron analysis can follow a published set of guidelines to ensure optimal confocal data series for proper dendritic spine quantification and neuron reconstruction. The paper, written by MBF Bioscience scientists and researchers from the Icahn School of Medicine at Mount Sinai in New York, was published in Current Protocols in Neuroscience.

The four protocols describe best practices for imaging and analyzing dendritic spines and entire neurons. Clearly laid out procedures specify necessary materials, image acquisition techniques, and analysis procedures with Neurolucida 360.

Imaging technique is crucial to obtaining unbiased, reproducible results. Clear, crisp images captured with an appropriate z-interval will make analysis with Neurolucida 360 easier and more accurate. Throughout the paper, the authors emphasize the importance of image scaling parameters and unbiased sampling for achieving repeatable results. They also discuss the benefits of correcting optical distortion, especially in the Z-plane, with deconvolution to acquire clear images – a process critical to getting the most accurate representation of dendrites and spines.

Dendritic spine analysis is traditionally performed through tedious, time-consuming manual techniques. According to the paper, this has spawned a growing interest in a more efficient solution for spine quantification and morphological analysis like the one Neurolucida 360 provides. A software platform for automatic neuron reconstruction and spine detection in a 3D environment, Neurolucida 360 offers a variety of benefits, including:

 

  • Fast and accurate spine detection and neuron reconstruction
  • Accurate spine classification and length quantification using a five-point segment that more accurately models the spine backbone.
  • 3 user-guided and automatic algorithms to accurately model neurons visualized with multiple methodologies and imaging techniques.
  • A large number of metrics, including volume, length, and surface area.

 

“We believe that the new quantitative software package, Neurolucida 360, provides the neuroscience research community with the ability to perform higher throughput automated 3D quantitative light microscopy spine analysis under standardized conditions to accelerate the characterization of dendritic spines with greater objectivity and reliability,” (Dickstein, et al. 2016)

Neurolucida 360 v2.7: A minor release with major new features

algorithm 123.jpg-1

The 3 algorithms in Neurolucida 360 were used in combination
to create a smooth, accurate reconstruction

Minor releases typically don’t include new features, but Neurolucida 360 isn’t an ordinary piece of software. Neurolucida 360 v2.7 has many new features and improvements including:

  • A new automatic tracing algorithm – Rayburst Crawl
  • Capture videos of your rotating neuron reconstructions for presentations and publications
  • New backbone length analysis for dendritic spines
  • Improved handling of images exceeding 10GB

With the addition of Rayburst Crawl, Neurolucida 360 now has 3 different algorithms for automatic neuron reconstruction. Why 3 algorithms? To give you the power to choose the one that works best with your images. Labeling specificity, staining intensity, and image signal-to-noise can vary widely within a specimen – making it impossible for a single tracing algorithm to work optimally in all situations.

If you want more control over your neuron reconstructions, the same 3 algorithms can be used in user-guided mode. You follow a dendritic branch or axon with your mouse cursor and the algorithm finds the center and thickness of the process. It combines the unrivaled human ability to identify and segment objects with the speed of a computer.

Try it for yourself.
