Why the Brain Loses Touch With Reality
Ever wonder why some people seem completely spaced out? It turns out half the normal population has a fold in the brain that makes their memories significantly less accurate.
What's the Latest Development?
A variation in a fold in the front of the brain accounts for why some people remember events very differently from how they actually happened, says a study just released from the University of Cambridge. Those who lacked the variation, called the paracingulate sulcus, were shown to have significantly weaker memories than those with the variation. Despite the experiment's results, all subjects judged themselves to have better-than-average memories.
What's the Big Idea?
The Cambridge researchers found that half the normal population lacks the variation that controls for accurate memory, which may help explain why memory is so notoriously unreliable. The results could also give insight into diseases like schizophrenia where patients have wild hallucinations that break completely with reality. It also begs the question of how much influence neuroscience will play in society as we come to understand more about the brain. Should witnesses to crimes be given MRI scans, for example?

Neuroscience research suggests it might be time to rethink our ideas about when exactly a child becomes an adult.
- Research suggests that most human brains take about 25 years to develop, though these rates can vary among men and women, and among individuals.
- Although the human brain matures in size during adolescence, important developments within the prefrontal cortex and other regions still take pace well into one's 20s.
- The findings raise complex ethical questions about the way our criminal justice systems punishes criminals in their late teens and early 20s.
Does believing in true love make people act like jerks?
- Ghosting, or cutting off all contact suddenly with a romantic partner, is not nice.
- Growth-oriented people (who think relationships are made, not born) do not appreciate it.
- Destiny-oriented people (who believe in soulmates) are more likely to be okay with ghosting.
A new method of growing mini-brains produces some startling results.
- Researchers find a new and inexpensive way to keep organoids growing for a year.
- Axons from the study's organoids attached themselves to embryonic mouse spinal cord cells.
- The mini-brains took control of muscles connected to the spinal cords.
