Generalized 3 Hz spike and wave discharges in a child with childhood absence epilepsy. Credit: Wikipedia. Research by Cardiff University has uncovered the brain activity that underlies absence epilepsy, offering new hope for the development of innovative therapies for this disabling disease. Absence epilepsy—the most common form of epilepsy in children and teenagers—causes episodes of […]Continue Reading ...
Worms lacking CEPsh glia (right) tend to abruptly pause in place, suggesting that these cells help regulate the immobility that accompanies sleep. Credit: Rockefeller University A good night of sleep entails about eight hours of blissful immobility—a state of near paralysis that, though welcome at night, would be inconvenient during the day. In a recent […]Continue Reading ...
Anxiety was traced by the CSHL team to the brain’s central amygdala, and to increased excitation of neurons that express the peptide somatostatin (SOM+ neurons). This initial step is demonstrated in these images, by comparing the amount of pink and blue fluorescence in the bottom right frame as compared with the frame directly above it, […]Continue Reading ...
A comparison of norepinephrine neurons from the locus coeruleus in mice revealed over 60 genes preferentially expressed in male neurons (blue) and over 70 genes preferentially expressed in female neurons (pink). Credit: Bernard Mulvey Using male individuals has long been a tradition in scientific mice studies. But new research enforces the importance of using a […]Continue Reading ...
Generalized 3 Hz spike and wave discharges in a child with childhood absence epilepsy. Credit: Wikipedia. Cannabidiol (CBD), a compound derived from the cannabis plant that does not produce a “high” and has been an increasing focus of medical research, was shown in a new large-scale, randomized, controlled trial to significantly reduce the number of […]Continue Reading ...
Credit: CC0 Public Domain Frequent sauna bathing is associated with a reduced risk of stroke, according to a new international study. In a 15-year follow-up study, people taking a sauna four to seven times a week were 61 per cent less likely to suffer a stroke than those taking a sauna once a week. This […]Continue Reading ...
Credit: CC0 Public Domain Sympathetic nerve activity to skeletal muscle blood vessels—a function of the nervous system that helps regulate blood pressure—increases during physiological and mental stress in people with chronic anxiety, a new study finds. Over time, this response may increase the risk of high blood pressure and heart disease, although the study did […]Continue Reading ...
Network model of the brain (right), alongside a pictorial representation of brain anatomy (left; from Wikimedia Commons). In the network model, the red path shows the quickest way to travel between the highlighted regions, only using three connections of the network. The green path shows the route identified by our navigation strategy, which use four […]Continue Reading ...
Credit: CC0 Public Domain High activity in a relatively poorly studied group of brain cells can be linked to aggressive behaviour in mice, a new study from Karolinska Institutet in Sweden shows. Using optogenetic techniques, the researchers were able to control aggression in mice by stimulating or inhibiting these cells. The results, which are published […]Continue Reading ...

Credit: CC0 Public Domain A new study in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging reports that people with obsessive–compulsive disorder (OCD) feel more distress when viewing images to provoke OCD-related emotions than their unaffected siblings. Although the unaffected siblings showed lower levels of distress, they had higher levels of brain activity in regions important for […]Continue Reading ...
