A New Theory for What’s Happening In the Brain When Something Looks Familiar

Researchers propose a new theory of what happens in the brain when we experience familiar seeming visual stimuli. The theory, dubbed sensory referenced suppression, suggests the brain understands different levels of activation expected for sensory input and corrects for it, leaving behind the signal for familiarity.

Our Attention Is Captured by Eye-Glance

When people make eye contact with another person, their attention is immediately solicited and this causes a distortion in temporal perception. However, the shift in time perception does not change when people glance at non-social items or objects.

Vision Impairment Is Associated With Mortality

Meta-analysis reveals those who have visual impairments or are blind have a higher risk of mortality compared to peers with better vision. The study found mortality risk was 29% higher in those with mild visual impairment and rose to 89% higher for those with severe visual impairments.

Differences Related to Sexual Orientation Found in the Brain

A new neuroimaging study reveals brain patterns that differentiate between men and women are less pronounced in non-heterosexual people. The differences occurred primarily in sensory processing areas of the brain, in particular areas associated with visual processing. Researchers say the brain differences could be linked to a genetic predisposition for same-sex sexual behaviors. The study reveals a neurobiological basis for same-sex attractions.
