Researchers show that powerful hierarchical situations make it easier to commit harmful actions, as agency and empathy are split across multiple individuals. http://dlvr.it/SZJBnY

Since their discovery over 100 years ago, neurons in the brain's olfactory bulb, called tufted cells, have been difficult to study. By leveraging new technology, neuroscientists were able to precisely dissect the neural activity of these tufted cells for the first time. They discovered the tufted cells were better at recognizing smells than mitral cells, their neighboring neurons in the olfactory bulb. Their findings offer new explanations for how the brain processes sensory information. http://dlvr.it/SZHplL

Docosahexaenoic acid (DHA) is associated with a greater capacity for selective and sustained attention in adolescents, while alpha-linolenic acid (ALA) is associated with lower impulsivity, according to a new study. The results confirm the importance of having a diet that provides sufficient amounts of these polyunsaturated fatty acids for a healthy brain development. http://dlvr.it/SZ7x8g

Simple computer-based neurocognitive training -- using positive words and pictures designed to boost self-worth -- prolongs the antidepressant effects of ketamine in people with treatment-resistant depression, researchers report. http://dlvr.it/SZ5XwS

Rendering the invisible visible is among scientists' favorite challenges. In their efforts to uncover how the olfactory system makes sense of thousands of otherwise invisible odors, scientists now have uncovered more of the cellular and molecular steps by which the high-precision neural circuitry of smell gets wired up in the nose and brain. http://dlvr.it/SZ4Vyt

Women who experience anxiety about their pregnancies give birth earlier on average than those who don't, according to new research. http://dlvr.it/SZ3CQY

Scientists have explored new techniques that may help distinguish between two different neurological conditions in patients with severe brain damage and or in a coma. http://dlvr.it/SYzlqY

Social avoidance is a common symptom of PTSD, and scientists working to better understand why have laboratory evidence that while stress hormone levels consistently increase in the immediate aftermath of a traumatic event, there can be polar opposite consequences in parts of the brain down the line. http://dlvr.it/SYvf66

Researchers have found regions in the woodpecker forebrain that show characteristics that until now have only been associated with vocal learning in animals and language in humans. The study shows that instead of being related to vocalization, activity in these brain regions is related to the characteristic tree drumming that gives woodpeckers their name. http://dlvr.it/SYrRTz

Deep learning models represent 'an entirely new paradigm for studying dementia.' http://dlvr.it/SYn0Fg

A study of moles reveals that cold weather -- not lack of food -- drives the rare phenomenon of reversible brain shrinkage in mammals. http://dlvr.it/SYjVWN

Monkeypox can sometimes lead to neurological complications such as encephalitis (brain inflammation), confusion or seizures, finds a new review of evidence. http://dlvr.it/SYgVQD

A type of brain cell that can renew itself is regulated by circadian rhythms, providing significant insights into how the body's internal clock may promote healing after traumatic brain injuries (TBI), according to new research. http://dlvr.it/SYczG5

Spinal cerebellar ataxia 6 (SCA6) is an inherited neurological condition which has a debilitating impact on motor coordination. Affecting around 1 in 100,000 people, the rarity of SCA6 has seen it attract only limited attention from medical researchers. To date, there is no known cure and only limited treatment options exist. Now, a team of researchers specializing in SCA6 and other forms of ataxia, have published findings that not only offer hope for SCA6 sufferers but may also open the way to developing treatments for other movement disorders. http://dlvr.it/SYcZW8

During development, the cells of an embryo divide until a fully functional organism emerges. One component of the cell is especially important during this process: the cell cortex. This fine network of hair-like filament structures (called actin) just below the cell membrane is the main determinant of cell shape and is involved in almost everything a cell does, such as moving, dividing, or sensing its environment. Yet, the cortex must first be built from single molecules, and if it is not built just right, the cells of an organism would never get to the right place to perform their functions. http://dlvr.it/SYSvpm

Human beings and fruit flies have very little in common -- at first sight. However, studying these flies it is in fact possible to find out more about human nature, particularly when it comes to depressive disorders. It is on this basis that scientists are attempting to gain a better understanding of depression-like states and thus improve means of treating them. http://dlvr.it/SYSW3Z

Although the brain is divided into two halves, it is not exactly a mirror image. Some functions are processed more on the left side, others more on the right. Scientists have now discovered heritable underpinnings of brain asymmetry and how much we share with monkeys. http://dlvr.it/SYPrpD

A study assessed resident physicians' perceptions, coping strategies and self-reported levels of depression, anxiety and stress experienced during the early phase of the pandemic. http://dlvr.it/SYPTSJ

The study suggests a previously unobserved relationship between body temperature and REM sleep, with REM sleep appearing to act like a 'thermostatically controlled brain heater.' http://dlvr.it/SYLQGz

The memory system alternates between periods of learning and remembering. These two functions are controlled by different neural circuits. Using an animal model, scientists recently identified a neural signal in the hippocampus, a brain region essential for forming and recalling memories, that enables the brain to alternate between remembering and learning modes. http://dlvr.it/SYL6H6
