| Amygdala found to have role in important pre-attentive mechanism in the brain Posted: 29 Jul 2021 03:36 PM PDT Researchers have shown how the amygdala, a brain region typically associated with fear, contributes to prepulse inhibition (PPI) by activating small inhibitory neurons in the mouse brain stem. The discovery advances understanding of the systems underlying PPI and efforts to ultimately develop medical therapies for schizophrenia and other disorders by reversing pre-attentive deficits. |
| A sleep study’s eye-opening findings Posted: 29 Jul 2021 03:35 PM PDT Getting more sleep, by itself, does not change work productivity or overall well-being for impoverished workers in India. Naps or better-quality sleep at night may have a bigger impact, according to a new study. |
| Tiny wireless device illuminates neuron activity in the brain Posted: 29 Jul 2021 03:35 PM PDT A team lights a path forward for improved treatment of conditions including addiction and epilepsy and chronic pain. In a new article, they report on a wireless transcranial optogenetic simulation device that can send light through the skull rather than physically penetrating the blood-brain barrier. |
| A blood test for your body clock? It's on the horizon Posted: 29 Jul 2021 11:34 AM PDT Sleep researchers have found it's possible to determine the timing of a person's internal biological clock via a single blood draw. Ultimately, the findings could lead to a simple blood test for assessing circadian rhythm and personalized recommendations for when people should eat, sleep, exercise and take medications. |
| How to make up your mind when the glass seems half empty? Posted: 29 Jul 2021 09:22 AM PDT Neuroscientists have connected some of the dots to reveal the brain networks that give anxiety influence over decisions. The group has published a review that synthesizes results from years of brain measurements in rats and primates and relates these findings to the human brain. |
| Adding color to your plate may lower risk of cognitive decline Posted: 29 Jul 2021 09:22 AM PDT A new study shows that people who eat a diet that includes at least half a serving per day of foods high in flavonoids like strawberries, oranges, peppers and apples may have a 20% lower risk of cognitive decline. The study looked at several types of flavonoids, and found that flavones and anthocyanins may have the most protective effect. |
| Fruit compound may have potential to prevent and treat Parkinson's disease Posted: 29 Jul 2021 09:22 AM PDT Researchers say they have added to evidence that the compound farnesol, found naturally in herbs, and berries and other fruits, prevents and reverses brain damage linked to Parkinson's disease in mouse studies. |
| Motivation depends on how the brain processes fatigue Posted: 28 Jul 2021 07:56 AM PDT How do we decide whether or not an activity which requires work is 'worth the effort'? Researchers have shown that the willingness to work is not static, and depends upon the fluctuating rhythms of fatigue. |
