Have you ever found it difficult to focus on a task due to background noise? Scientists are studying just how these sounds impact our brain activity — and what that impact means for designing neurotechnology.
Read moreScientists have shown that delta waves emitted while we sleep are not generalized periods of silence during which the cortex rests, as has been described for decades in the scientific literature. Instead, they isolate assemblies of neurons that play an essential role in long-term memory formation.
Read moreScientists are developing powerful new devices and technologies to monitor and regulate brain activity. To ensure NIH keeps pace with rapid technological development and help clinicians and researchers ethically fit these new tools into practice, a new article highlights potential issues around and offers recommendations about clinical research with both invasive and noninvasive neural devices.
Read moreNon-invasive brain stimulation is to be trialled for the first time alongside advanced brain imaging techniques in patients who are minimally conscious or in a vegetative state.
Read moreScientists discover that a brain region known to control sex and violence contains rare cell types that differ in male versus female mice.
Read moreNew research could help explain why memory in old age is much less flexible than in young adulthood. Through experiments in mice the researchers discovered that there were dramatic differences in how memories were stored in old age, compared to young adulthood.
Read moreA brain mapping technique called BARseq is capable of mapping thousands of neurons in a single mouse, at single neuron resolution, while also detailing which neuron expresses what genes. It could be a game-changer for how neuroscientists look at brains.
Read moreProlonged exposure to blue light, such as that which emanates from your phone, computer and household fixtures, could be affecting your longevity, even if it's not shining in your eyes. New research suggests that the blue wavelengths produced by light-emitting diodes damage cells in the brain as well as retinas, according to a new study in a model organism.
Read moreA study has now found that a type of opsin known as neuropsin is expressed in the hair follicles of mice and synchronize the skin's circadian clock to the light-dark cycle, independent of the eyes or brain. Researchers now want to see if skin heals better if it's exposed to certain types of light.
Read moreUsing optogenetic and chemogenetic techniques, researchers have identified brain circuits underlying hunger-induced changes in the preferences for sweet and aversive tastes in mice. These circuits involved Agouti-related peptide-expressing neurons, which projected to glutamate neurons in the lateral hypothalamus. From there, glutamate neurons projecting to the lateral septum increased sweetness preferences, and glutamate neurons projecting to the lateral habenula decreased sensitivity to aversive tastes.
