A new study reveals areas of brain where recognition and identification occur.

Researchers have identified a hippocampal neural network that activates during stress. Activity in a hippocampal-hypothalamus network predicts greater feelings of stress, while connectivity between the hippocampus and dorsolateral prefrontal cortex predicts less stress.

Researchers have identified27 protein biomarkers that can predict whether a patient with COVID-19 is likely to develop severe coronavirus symptoms.

While the amount of antibodies generated varies widely in patients who have recovered from coronavirus, most people generate at least some antibodies which are intrinsically capable of neutralizing the SARS-CoV-2 virus according to a new study.

Twenty-nine genes have now been identified as being linked to problematic alcohol use. 

Toxic versions of the protein tau are believed to cause death of neurons of the brain in Alzheimer’s disease. A new study published in Nature Communications shows that the spread of toxic tau in the human brain in elderly individuals may occur via connected neurons. The researchers could see that beta-amyloid facilitates the spread of toxic tau.

Certain personality traits could increase the risk of developing mild cognitive impairment, a new study reports.

The anesthetic drug ketamine has been shown, in low doses, to have a rapid effect on difficult-to-treat depression. Researchers at Karolinska Institutet now report that they have identified a key target for the drug: specific serotonin receptors in the brain. Their findings, which are published in Translational Psychiatry, give hope of new, effective antidepressants.

Finally this week, a new study shows some infants can identify differences in musical tones at six months.
