For people with insomnia, sleep does not reduce the shame of an embarrassing experience. For them, the distress does not fade; in fact, it can get worse with recall.
Brain activity differences may help explain why distress from bad memories grows stronger in people with insomnia but fades in those without insomnia.
The researchers conducted in-depth analyses of how touch signals are transferred and processed in neurons of various parts of the brain and the latest studies have been published in Cell Reports and Frontiers in Cellular Neuroscience. The experiments were conducted on anaesthetised rats.
“We immediately realised that our findings deviated strongly from the accepted view that different parts of the brain are responsible for different specific functions,” says Henrik Jörntell, one of the researchers behind the study.
A drug commonly used to treat multiple sclerosis may, after necessary modifications, one day be used to treat patients with epilepsy, researchers in Prof. Inna Slutsky’s lab at the Sackler Faculty of Medicine and Sagol School of Neuroscience at Tel Aviv University have discovered.
This is good news for patients with Dravet syndrome, one of the most dangerous forms of childhood epilepsy, for which there is currently no effective treatment.
According to a new study published on April 29 in Neuron, Tel Aviv University researchers uncovered a piece of a puzzle that has eluded scientists for 100 years of studying homeostasis: What is the mechanism that maintains activity set points in neural circuits?

MeiraGTx’s founders were interested in those uses; the biotech’s programs today are in diseases of the eye, salivary gland and brain.
But “we wanted to have a broader perspective on how you could potentially use gene therapy” too, CEO Alexandria Forbes says.
That vision is a high-tech, futuristic one, in which the human body can essentially become a medicine-making factory, enabled by gene therapy. But it’ll require more research, and is still years from fruition.
Stem cells are pluripotent cells, having a property of differentiating into various types of cells of human body. Several studies have developed mesenchymal stem cells (MSCs) from various human tissues, peripheral blood and body fluids. These cells are then characterized by cellular and molecular markers to understand their specific phenotypes. Dental pulp stem cells (DPSCs) are having a MSCs phenotype and they are differentiated into neuron, cardiomyocytes, chondrocytes, osteoblasts, liver cells and β cells of islet of pancreas. Thus, DPSCs have shown great potentiality to use in regenerative medicine for treatment of various human diseases including dental related problems. These cells can also be developed into induced pluripotent stem cells by incorporation of pluripotency markers and use for regenerative therapies of various diseases. The DPSCs are derived from various dental tissues such as human exfoliated deciduous teeth, apical papilla, periodontal ligament and dental follicle tissue. This review will overview the information about isolation, cellular and molecular characterization and differentiation of DPSCs into various types of human cells and thus these cells have important applications in regenerative therapies for various diseases. This review will be most useful for postgraduate dental students as well as scientists working in the field of oral pathology and oral medicine.

(Editor’s note: This podcast is from The Not Old – Better Show.)
As part of our Inside Science and Technology interview series, today’s show is an interview with Dr. Pradeep Reddy, a research scientist at the Salk Institute for Biological Studies.
As we all know in the Not Old Better Show audience, aging is a leading risk factor for a number of debilitating conditions, including heart disease, cancer and Alzheimer’s disease, to name a few. This makes the need for anti-aging therapies all the more urgent. Now, Salk Institute researchers have developed a new gene therapy that is showing promise as a possible way to decelerate the aging process in humans. It uses CRISPR genome-editing technology.
