Neurolucida and Neurolucida Explorer Used for 3D Reconstruction and Quantitative Analysis Researchers used Neurolucida to reconstruct a newly discovered type of neuron found only in the human brain, according to a study published in the journal Nature Neuroscience. Known as “rosehip” neurons because of the way they resemble a rose after its petals have fallen off, these cells feature compact, bushy axonal arborizations. Found in the first...

Scientific research shows that women are twice as likely as men to develop stress disorders. Why are women more sensitive than men to stress? A recent research study presents new evidence that estrogen could play a role. The symptoms of disorders like major depressive disorder and post traumatic stress disorder lead neuroscientists to speculate that a dysfunction occurs in the way the medial prefrontal cortex connects...

When your mouth is dry, your joints are stiff, or your heart is inflamed because your immune system is attacking your own body, chances are you're suffering from a little stress. A recent study shows that there may be physiological reasons why patients with autoimmune diseases experience increased levels of anxiety. Scientists at the City University of New York Medical School, Columbia University, and the University...

Myelin, which insulates axons in the central nervous system is produced by oligodendrocytes. But not all oligodendrocytes are equal. Led by Dr. Jonathan Vinet of the Université Laval in Quebec, scientists have identified three different types of oligodendrocytes in the mouse hippocampus: "ramified," "stellar," and "smooth." Each type displayed varying morphological characteristics, mainly in shape, volume, and branching behavior, which led the researchers to believe that the...
