Distracted people can be ‘smell blind’

‘Inattentional smell blindness,’ or inattentional anosmia, has been proven to exist. Just as it has previously been found that people can miss visual cues when they are busily engaged in a task, the same is true of smells. However, with smells there is…

What effect does transcranial magnetic stimulation have on the brain?

Researchers have gained new insights on the question of how transcranial magnetic stimulation (TMS) effects functional interconnectivity of neurons. For visualization, they employed fluorescent dyes which provide information on the activity of neurons …

Neurons ripple while brains rest to lock in memories

Researchers develop a computational tool to analyze waves of firing neurons in the hippocampus while animals are at rest and determine which neurons represent the recall or reactivation of patterns linked to specific memories.

Maternal depressive emotion associated with children’s sleep problems

Maternal depressive mood during the prenatal and postnatal periods is related to child sleep disturbances, according to recent pilot data from a longitudinal cohort study in kindergarten children.

Sex robots may do more harm than good

According to their makers, sex robots can bring many health-related benefits to users. But how realistic are these claims? A new study investigates.

I saw that. Brain mechanisms create confidence about things seen

At the threshold of what we call consciousness is a brain function that makes you feel confidently aware that you are actually seeing what you see. Psychologists have observed mechanisms involved in making it work.

Protein pair quickly makes memories of new places

A new study shows that the brain’s ability to rapidly form memories of new places depends on the timely interaction of two proteins: FMRP and neurogranin.

Brain structure may predict diet success

Differences in the structure of the prefrontal cortex predict an individual’s ability to make healthier food choices, according to a new analysis of previous research in healthy men and women. The article suggests an important role of these anatomical …

Speed-accuracy tradeoff turns up gain in the brain

Widespread changes in neural activity enable people to quickly make a decision by ‘turning up the gain in the brain,’ suggests a recent human study. The findings help to resolve a central issue in our understanding of decision-making.

How does alcohol influence the development of Alzheimer’s disease?

Research has found that some of the genes affected by alcohol and inflammation are also implicated in processes that clear amyloid beta — the protein that forms globs of plaques in the brain and which contributes to neuronal damage and the cognitive i…
