Oral contraceptives modify the menstrual cycle. What’s less well known is that they also reach the brain, particularly the regions important for regulating emotions.
More invasive devices have prompted new debates about privacy and freedom. But it’s important to keep in mind that other technologies already sense and shape our thoughts, a neuroethicist argues.
New research offers insights into the brain after COVID-19 that may have implications for our understanding of long COVID-19 and how the disease affects our senses of taste and smell.
On Oct. 1, 1971, Godfrey Hounsfield’s invention took its first pictures of a human brain, using X-rays and an ingenious algorithm to identify a woman’s tumor from outside of her skull.
Reduced brain volume in people who have experienced COVID-19 resembles brain changes typically seen in older adults. The implications of these findings are not yet clear.
Despite its huge complexity, your brain directs its neural traffic in relatively straightforward ways when approaching cognitively demanding tasks such as puzzles.
These tiny nanoparticles might provide a new way to see what’s happening in the brain and even deliver treatments to specific cells – if researchers figure out how to use them safely and effectively.
Hollywood pushes a fantasy version of what neuroscience can do in the courtroom. But the field does have real benefits to offer, right now: solid evidence on what would improve prisons.
It can be very hard for people to accept that they – or their family member – are not to blame for their mental illness. Seeing the evidence in a scan can make a difference.
BCI devices that read minds and act on intentions can change lives for the better. But they could also be put to nefarious use in the not-too-distant future. Now’s the time to think about risks.
We can’t observe the brain activity of extinct human species. But we can observe modern brains doing the things that our distant ancestors did, looking for clues about how ancient brains worked.
