Attractants prevent nerve cell migration
A vision is to implant nerve precursor cells in patients with Parkinson's and Huntington's diseases. However, the implanted nerve cells frequently do not migrate as hoped. Scientists at the Institute for Reconstructive Neurobiology at Bonn University have now discovered an important cause of this: attractants secreted by the precursor cells prevent the maturing nerve cells from migrating into the brain. The results are presented in the journal Nature Neuroscience. (2013-11-21)

Scientists pinpoint jealousy in the monogamous mind
Scientists find that in male titi monkeys, jealousy is associated with heightened activity in the cingulate cortex, an area of the brain associated with social pain in humans, and the lateral septum, associated with pair bond formation in primates. A better understanding of jealousy may provide important clues on how to approach health and welfare problems such as addiction and domestic violence, as well as autism. (2017-10-19)

Biomarkers facilitate early detection of glaucoma
Researchers at Ruhr-Universit├Ąt Bochum have identified new potential biomarkers that may facilitate early detection of glaucoma in patients.

Adaptation in single neurons provides memory for language processing
To understand language, we have to remember the words that were uttered and combine them into an interpretation. How does the brain retain information long enough to accomplish this, despite the fact that neuronal firing events are very short-lived? Hartmut Fitz from the Max Planck Institute for Psycholinguistics and his colleagues propose a neurobiological explanation bridging this discrepancy. Neurons change their spike rate based on experience and this adaptation provides memory for sentence processing. (2020-08-12)

Monkey brains signal the desire to explore
Sticking with what you know often comes at the price of learning about more favorable alternatives. Managing this trade-off is easy for many, but not for those with conditions such as Alzheimer's disease or obsessive-compulsive disorder who are trapped in simple routines. (2009-09-04)

Controlling and visualizing receptor signals in neural cells with light
Using a novel optogenetic tool, researchers have successfully controlled, reproduced and visualized serotonin receptor signals in neural cells. To this end, they modified a photosensitive membrane receptor in the eye, namely melanopsin. They were able to switch the receptor on and off using light; it also acted like a sensor indicating via fluorescence if specific signalling pathways in the cell had been activated. The sensor was, moreover, specifically designed to migrate to those domains in the neural cells that are sensitive to the neurotransmitter serotonin. (2019-02-14)

Uncovering the secrets of sleep and circadian rhythms
Our circadian rhythms tell us when it's time to sleep and energize us at different times of the day; evidence suggests it also plays a role in the development of diseases such as cancer. Elsevier, a world-leading provider of scientific, technical and medical information products and services, announces the launch of a new open-access journal that will publish latest research on sleep and circadian rhythms. (2015-10-14)

Signaling pathway for ginsenoside Rb1 promoting hippocampal neuronal neurite outgrowth
The main pathological changes of Alzheimer's disease include amyloid-beta protein-induced hippocampal neuronal injury and neurite outgrowth impairment. Phosphatidylinositol 3-kinase (PI3K)/Akt pathway and mitogen-activated protein kinase pathway are the important signaling pathways respectively responsible for regulating synaptic plasticity and neuronal survival. In view of the fact that ginsenoside Rb1 exhibits anti-aging and anti-dementia effects, Prof. Qionglan Yuan and her team, Department of Anatomy & Neurobiology, Tongji University School of Medicine, Shanghai, China performed a study, in which ginsenoside Rb1 was used, and found that ginsenoside Rb1 promoted hippocampal neuronal neurite outgrowth and protected against neurotoxicity induced by amlyloid-beta via a mechanism involving Akt and extracellular signal-regulated kinase 1/2 signaling. (2014-07-14)

Tone of voice matters in neuronal communication
Neuronal communication is so fast, and at such a small scale, that it is exceedingly difficult to explain precisely how it occurs. An observation in the Neurobiology course at the Marine Biological Laboratory (MBL), enabled by a custom imaging system, has led to a clear understanding of how neurons communicate with each other by modulating the ''tone'' of their signal, which previously had eluded the field. (2020-09-28)

Why do schizophrenics smoke?
Eighty to ninety percent of schizophrenics smoke. In a new research article in the upcoming issue of Molecular Psychiatry (Nature Publishing Group), researchers in Canada investigate the mechanism by which the rewarding properties of nicotine may be enhanced. They suggest that drugs used to treat schizophrenia may block selectively the aversive properties of nicotine, thus increasing the vulnerability to nicotine's rewarding and addictive properties in schizophrenics by inducing a unique, drug-vulnerable phenotype. (2003-02-13)

Neurobiological insights for psychoanalysts working with autistic children

Postpartum depression & anxiety distinct from other mood disorders, brain studies suggest
On the surface, postpartum depression looks much like other forms of depression. New mothers struggling with it often withdraw from family and friends, lose their appetites, and of course, feel sad and irritable much of the time. However, many clinicians have underestimated the uniqueness of mood and emotional disorders that arise during pregnancy or shortly after giving birth. Psychologists explore the neurobiology of postpartum depression and anxiety in a Review published in Trends in Neurosciences. (2017-01-24)
