This Is What Your Brain Does When You’re Not Doing Anything
When your mind is wandering, your brain’s “default mode” network is active. Its discovery 20 years ago inspired a raft of research into networks of brain regions and how they interact with each other......»»

Simplified voice box enriches human speech
An ongoing debate among scientists, on why chimpanzees and other nonhuman primates cannot speak or sing like humans, has focused mainly on evolutionary changes in human brain development. Attention has now expanded to anatomical changes of the voice.....»»
New study shows that aging neutralizes sex differences in the brain
When male and female fruit flies age, their brains become desexualized. Age-related changes take place in both sexes, but the male brain becomes feminized to a larger extent than the female brain becomes masculinized. This is the conclusion of a stud.....»»

Is brain fog limited to humans?
Is brain fog a condition limited to humans? "Infectious disease and cognition in wild populations," a recently published paper in Trends in Ecology & Evolution, answers that question. In a review of the studies, it explores whether learning, memory,.....»»
Jumping spiders may experience something like REM sleep
If it's an analog of mammalian REM sleep, then it evolved very early. Enlarge / This little guy looks too perky to need a nap. (credit: Tony Liu) Our sleep is marked by cycles of distinct brain activity. The most well-known of.....»»
Using a supercomputer to find the best way to mix two fluids
A pair of researchers, one with the Max Planck Institute of Brain Research, the other with Imperial College, has found more efficient ways to mix two fluids using simulations run on a supercomputer. In their paper published in the journal Physical Re.....»»
Researcher is studying materials whose traits resemble those of the human brain
In its heyday, UIUC's Blue Waters was one of the world's top supercomputers. Anyone who was curious could drop by its 30,000-square-foot machine room for a tour, and spend half an hour strolling among the 288 huge black cabinets, supported by a 24-me.....»»
Developing AI models based on human brain activity to solve self-locating and navigation issues
Imagine a future where your hometown gets destroyed by some calamity. In the aftermath, how easily could you locate your home after your neighborhood has been transformed into a giant maze of rubble, leaving only minimal landmarks?.....»»

Brain-Computer Interfaces at Home: Interview with Dr. Solzbacher of Blackrock Neurotech
Blackrock Neurotech, a medtech company based in Salt Lake City, has pioneered an array of brain-computer interface technologies. Medgadget last spoke with Blackrock Neurotech a year ago about their thought-to-text brain computer interface, but since.....»»
Imaging the brain with ultrasound waves
Both ultrasound for medical imaging and seismology for imaging the Earth's interior measure the propagation of waves through matter. For example, when seismic waves encounter material differences in the Earth's interior, such as between different roc.....»»
Researchers determine the complex structure of the receptors related to opioid addiction
A study published in Pharmacological Research reveals the oligomeric molecular structure of the MOR-Gal1R complex, a component present in the brain which is involved in the analgesic and addictive effects of certain opioids. The study includes the pa.....»»
Scientists develop new biomimetic formulation for treating glioblastoma
Glioblastoma multiforme (GBM) is an aggressive brain cancer with a poor prognosis and few treatment options. New and effective approaches for GBM treatment are therefore urgently needed......»»

Study of published research suggests both brain size and brain-to-body ratio are factors in intelligence in birds
An international team of researchers has found evidence that both total brain size and the size of a brain in relation to the body are factors that determine intelligence in animals. In their paper published in the journal Nature Ecology and Evolutio.....»»
