When it comes to processing information about motion, neurons in the ventral intraparietal area of the brain are more flexible in switching between reference frames. The findings could be used to develop neural prosthetics designed for motion control.
Findings shed light on repulsion, or why the brain treats similar environments as though they are more different than a pair of environments that have nothing in common.
When you've acted in an uncooperative or untrustworthy way, the way you smile could either help heal or hinder social relationships. Those whose smiles reflected reward, or a signal that they were happy, or a smile of dominance, which reflects a feeling of superiority, appeared to be untrustworthy and unlikely to change their deceptive nature. However, a smile of affiliation was perceived as an attempt to make amends, restoring levels of trust.
Researchers have identified neurons in the brains of praying mantises that are able to compute 3D direction and distance. The findings may help to develop better technology for machine and robotic vision.
Elevated levels of lead in the blood of children was associated with structural changes in the brain during mid-life. Those with higher levels of lead exposure as children had decreased hippocampal volume and structural deficits in white-matter integrity.
