Simple tasks don’t test brain’s true complexity

New research strategies are needed to find out how information flows through the brain’s neural networks, according to neuroscientists. In a new article, the researchers suggest using complex experiments to test the most important properties of these n…

Brain imaging reveals neural roots of caring

When others suffer, we humans empathize. Our feelings of empathy take different forms, such as distress when we imagine and internalize someone’s pain and compassion as we sympathize with their condition. These different feelings involve distinct patte…

Brain’s hippocampus can organize memories for events as well as places

The hippocampus can generalize, putting not just places but also events into sequence by changing the neural code in the rat brain, new research demonstrates.

Overriding the urge to sleep

The discovery of neurons that control arousal has implications for insomnia and other sleep disorders, report investigators.

Culprit hidden in plain sight in Alzheimer disease development

A new study heightens concerns over the detrimental short- and long-term impact of airborne iron-rich strongly magnetic combustion-derived nanoparticles present in young urbanites’ brains.

Brain scans differentiate two types of empathy

From fMRI scans, researchers find distinct brain markers for empathic care and empathic distress and show that they link differently to eight emotions.

Amygdala activity predicts posttraumatic stress disorder

Neuroimaging measures of emotional brain function after acute trauma may help predict whether a person will develop posttraumatic stress disorder (PTSD), according to a new study. The study reports an association between the activity of two key brain r…

Culture affects how people deceive others say researchers

Psychologists have discovered that people’s language changes when they lie depending on their cultural background.

Predicting autism: Study links infant brain connections to diagnoses at age two

In previous studies, researchers linked infant brain anatomy differences to autism diagnoses at age two. Now they show differences in functional connections between brain regions at 6 months to predict autism at age two.

Small group of neurons modulates the amount of insulin that the pancreas must produce

A new study emphasizes the importance of the neuronal mechanisms in the detection of nutrients and the control of glucose levels. The results help to understand diabetes in greater detail.
