According to scientists at the Hotchkiss Brain Institute in Calgary, Canada, there is evidence for increased neurogenesis in adult mice reared by two parents. Their study also describes other interesting findings, such as the fact that increased neurogenesis persists in the next generation, or that the effects of differences in rearing affect males and females differently. Using Stereo Investigator to perform a stereological assessment of proliferating cells...

Researchers at the Waisman Center (University of Wisconsin-Madison) just took a big step in their quest to develop regenerative medicines for treating Parkinson's, Alzheimer’s, and other neurodegenerative diseases. They used human embryonic stem cells to restore memory and learning in disabled mice. The study, published last month in Nature Biotechnology, "is the first to show that human stem cells can successfully implant themselves in the brain...

Spinal cord injuries can result in a range of physical disabilities from slight loss of motor function to major paralysis, but little is known about the mechanisms underlying the damage. Scientists affiliated with the Miami Project to Cure Paralysis at the University of Miami are gaining knowledge about how the nervous system responds to spinal cord injuries. Their latest study, published last month in the...

A stroke patient is rushed to the hospital. Deprived of oxygen-rich blood, brain cells have already died, and more damage will probably occur in the hours and days to come. But researchers at the University of South Florida and the University of Padova in Italy say a two-part package administered through the body, rather than directly into the brain, may be the key to staving...

If a head gets hit hard enough, the trauma occurs instantly. Neurons die, the brain swells as microglia cells rush to the damaged area, and the protective armor known as the blood brain barrier might even rupture. But it doesn't end there. Long term effects include cognitive impairment, loss of sensory processing, and susceptibility to neurodegenerative diseases like Alzheimer's. Researchers at the University of South Florida say...

There is very little known about Huntington’s disease (HD), a fatal neurodegenerative disease leading to total physical and mental decline that affects 30,000 Americans today. Researchers have been developing transgenic mouse models to mimic human HD. A new model, the zQ175 knock-in, developed by Menalled et al. (2012) appears to more closely mimic human HD progression in the zQ175 KI than previous mouse models. A recently published...

Dr. Erich Jarvis spends a lot of time with songbirds. At his Duke University lab, Jarvis, a Stereo Investigator user, studies the neurobiology of vocal communication. Since his feathered friends learn song much like humans learn speech, they're a favorite model. But Dr. Jarvis says mice sing too, and new research says they can learn new tunes. “We investigated the mouse song system and discovered that it...

Some children raised in orphanages grow up to develop social disorders, and there's not all that much modern medicine can do about it. But scientists at Harvard Medical School are working on gaining a better understanding of how early isolation affects a developing brain. Their research gives new insight into the mechanisms at play, and indicates that timing and healthy myelination are crucial. “Social isolation from...

Commonly used as a human anaesthetic and animal tranquilizer, the experimental drug ketamine became famous in the last two decades as a hallucinatory club drug known as “Special K.” Now, researchers at Yale University say the drug is beneficial in treating depression by increasing synaptic connections in parts of the brain that regulate mood and cognition. Dr. Ronald Duman, who uses Stereo Investigator and Neurolucida at...
Read More Long-time MBF customers at the University of Rochester Medical Center are considered leading experts in researching myelin diseases. They recently published a review article in Science titled “Glial Progenitor Cell-Based treatment and Modeling of Neurological Disease” in which they featured output from Stereo Investigator in the Figure 2 section to illustrate chimeric brains. {Glial Progenitor Cell–Based Treatment and Modeling of Neurological Disease Steven A. Goldman, Maiken Nedergaard, and Martha S....
