What's New

Version 2025

See the current Release Notes or all Release Notes for Neurolucida Explorer.

New features and improvements in Neurolucida Explorer

• The new Explore ribbon includes a suite of tools for visualizing data using color. You can create heat-map style images of detected/modeled structures in data files that can provide new perspectives on their biological significance.

• New Spatial Proximity analysis for somas, trees, vessels and puncta provides insights into the distribution of different object types by calculating nearest neighbor distances.

• Custom spine classification added to the Dendrite Spines analysis results. Custom spine classifications can be created and assigned when creating data files in Neurolucida or Neurolucida 360.

• Updated the minimum and maximum cross-sectional area analyses in Punctum Details analysis.

• Added the ability to perform Convex Hull analysis on vessels.

• Improved Puncta Density analysis user interface making it easier to select options.

• Set name is now included in Batch export of individual files if sets were created in Neurolucida or Neurolucida 360.

• Vessel analyses are now available in Batch export.

• Improved the speed of Puncta Details analysis.

• Updates to the Closed Surface analysis options

• Improved the speed of Closed Surface analysis when a data file contains many trees and vessels.

• Improved support for multi-user computers.

• Updated licensing information in File menu.

Recent previous updates

• Update to offline software licensing. Due to updates to the Neurolucida Explorer activation process, systems that that do not have access to the internet or have intermittent/unreliable internet access require reactivation. View instructions for offline software activation.

• Puncta nearest neighbor analysis updated to report puncta in all channels

• Added a new option to save all results to a single Excel file

• Somas were added to the Puncta colocalization analysis

• Closed surface analyses can now be conducted with more structures, including spines and varicosities

• An alert is now displayed when a proposed file name exceeds the 30-character limit

• The recent file list now updates during Neurolucida Explorer sessions

• The results tables have been updated throughout Neurolucida Explorer to enhance clarity and usability

• New ability to set the interval for the Tree Interval analysis (one of the many Branched structure analyses)

• Data files that include results from using the Detect Orientation tool now display orientation arrows. The vector coordinates and eigenvalues are also now included in the Fiber Orientation analysis report.

• Convex Hull report now includes the Feret min and max.

• Vessel analyses are available in Neurolucida Explorer to accompany the Neurolucida 360 Ultra package, which includes advanced modeling features and enables you to explore the intricate dynamics of neuronal and vascular interactions with a single software package. Click here to learn more.

• Fractal Analysis was added to the software

• The Spine Details report can now include the Segment ID

• The Sholl analysis can now report the number of puncta, puncta volume and surface area

• Puncta Distance from Additional Structures report can now include the spine-type information

• New Terminal Spine Density analysis added

• Puncta are now highlighted when selected

• Set scaling feature was returned to the View ribbon

• Distance along branch analysis has been added to the available Punctum analyses

• Polar histogram, Dendrogram and Fan In analyses are now available for Batch analysis and export
