Decoding the neural basis of affective empathy: How the brain feels others’ pain

A research team has uncovered key insights into how the brain processes others’ distress. Using miniature endoscopic calcium imaging, the researchers identified specific neural ensembles in the anterior cingulate cortex (ACC) that encode empathic freez…

Humans have a long way to go in understanding a dog’s emotions

New research has revealed that people often do not perceive the true meaning of their pet’s emotions and can misread their dog. The reasons for this are many and include a human misunderstanding of dog expressions due to a bias towards projecting human…

Worldwide study finds high rates of depression and anxiety in people with chronic pain

A novel analysis of more than 375 published studies concluded that the association between chronic pain and rates of depression and anxiety is staggering. The study found that 40% of adults with chronic pain experienced ‘clinically significant depressi…

Paralyzed man moves robotic arm with his thoughts

Researchers have enabled a man who is paralyzed to control a robotic arm through a device that relays signals from his brain to a computer. He was able to grasp, move and drop objects just by imagining himself performing the actions.

Memory is impaired in aged rats after 3 days of high-fat eating

Just a few days of eating a diet high in saturated fat could be enough to cause memory problems and related brain inflammation in older adults, a new study in rats suggests.

Brain mapping unlocks key Alzheimer’s insights

Researchers have used a new brain-mapping technique to identify memory-related brain cells vulnerable to protein buildup, a key factor in the development of Alzheimer’s disease, an incurable, progressive brain disorder that slowly destroys memory and t…

Alzheimer’s treatment may lie in the brain’s own cleanup crew

A new study suggests a promising alternative to previous attempts to remove the sticky, toxic amyloid beta plaques from brains with Alzheimer’s Disease: enhancing the brain’s own immune cells to clear these plaques more effectively. The findings could …

High temperatures could affect brain function in preadolescents

Exposure to high ambient temperatures is associated with lower connectivity in three brain networks in preadolescents, suggesting that heat may impact brain function.

Repurposed ALS drug becomes imaging probe to help diagnose neurodegeneration

Scientists used positron emission tomography (PET) with edaravone, a drug used to treat ALS, to detect oxidative stress, which leads to brain damage, offering a clear path to detecting neurological conditions.

For some, childhood adversity can promote resilience to anxiety disorders

Research has shown that young people who face adversity such as traumatic or stressful events during brain development are 40% more likely to develop anxiety disorders by adulthood. But most people who endure these experiences during childhood and adol…
