Humans take cues from facial expressions when it comes to evaluating another person's expressions whether happy, sad or angry. Neurons in a part of the brain called the amygdala "fire" in response to the visual stimulation as information is processed by the retina, the amygdala and a network of interconnected brain structures. Some of these regions respond just to the actual features of the face, whereas others respond to how things appear to the viewer, but it is unknown where ...

Freeze-Storage Egg Banking Set to Revolutionise Egg Donation

Posted:

By enabling freeze-storage egg-banking, the rapid freezing technique of vitrification is set to revolutionise egg donation as a fertility treatment. The cryopreservation of eggs was one of IVF's continuing challenges until the widespread introduction of vitrification; the older slow freezing methods induced the formation of ice crystals, which could cause damage to several structures of the egg. Thus, as demand for egg donation increases as a treatment for age-related ...
