Two 2014 Nobel Prize Laureates Used Neurolucida in their Groundbreaking Research

Drs. May-Britt and Edvard Moser were awarded the 2014 Nobel Prize in Physiology or Medicine for discovering the cells that form a network for spatial navigation in the brain, and we’re proud to say they are MBF Bioscience customers and used Neurolucida in their research.

In 2006, the Norwegian husband and wife team published a paper in the journal Science entitled “Conjunctive Representation of Position, Direction, and Velocity in Entorhinal Cortex” – a pivotal step in a line of research initiated in 1971 by co-laureate Dr. John O’Keefe (The Hippocampus as a Spatial Map). In their study, the scientists used Neurolucida to create 3D reconstructions of a complex network of neurons that make it possible for rats, and other animals, including humans, to navigate the world around them.

Anorexia Accelerates the Development of the Rat Hippocampus


This image stack was used in the study to analyze spine density. Image courtesy of Tara Chowdhury, Ph.D. first author of the study.

To find out how anorexia nervosa changes the brain, scientists at New York University are studying a rat model of the disease called activity-based anorexia (ABA). Previously, they discovered that ABA rats develop unusually robust dendritic branching of neurons in part of the hippocampus. Their new study takes those findings a step further, illuminating more differences between the brains of healthy versus ABA rats, and offering evidence that ABA rats may be developing too early, closing a critical period of development too soon.

But before making any conclusions about ABA brains, the researchers made some interesting discoveries about normal brain development. Using Neurolucida to analyze CA1 pyramidal cells in the stratum radiatum layer of the ventral hippocampus, they found that after puberty, around postnatal day 51, dendrites go through a growth spurt, more than doubling the number of branches seen seven days earlier. This growth spurt is followed by a decrease, or a pruning, which the researchers say is part of the normal maturation process.

Scientists Use Neurolucida to Create 3D Reconstructions of Placental Villous Trees

(a,b) Comparison of the microscopic aspects of a thin (4–6 μm) histological section of a human placenta after staining with hematoxylin/eosin (a) with the microscopic aspects of a whole-mount isolated villous tree after staining with hematoxylin (b). The scale bars in a and b are 250 μm. (a) Various cross- and longitudinal sections of villi can be recognized. The stromal architecture inside the sectioned villi is visible. The cross-sections of branches belong to an unknown number of villous trees. (b) A single villous tree is visible, and branches are not sectioned. The hierarchical positions of nodes (branching points) and the branching topology can be recognized.

(a,b) Comparison of the microscopic aspects of a thin (4–6 μm) histological section of a human placenta after staining with hematoxylin/eosin.

When neuroscientists started studying neurons in 3D, it revolutionized brain science. Now, for the first time, scientists are using this same technology to study the human placenta, and they’ve made some fascinating new discoveries about its structure.

Using Neurolucida to create 3D reconstructions of villous trees – three-dimensional structures in the placenta that facilitate gas and nutrient exchange between the fetus and mother – researchers in Munich, Germany uncovered a wealth of information about their architecture.

For the first time, they analyzed the complexity of villous tree branches and branching, determined the number and location of nodes (branching points), and measured branch angles, discovering a surprising correlation between the branching angle of terminal branchesand the fetoplacental weight ratio (BW/PW) – a calculation commonly used to measure fetal health in prenatal medicine.

“The results show that 3D analysis with Neurolucida reaches beyond the horizons of 2D histology, the current gold standard in placenta morphology/pathology,” said Dr. Hans-Georg Frank, an author of the study.
