      Magnetoencephalography is a technique used to measure the magnetic fields produced by electrical activity in the brain. It is a non-invasive method that can provide high temporal and spatial resolution of brain activity. In the context of the research paper, the authors mention a study by Strauss and Dehaene that focused on electro- and magnetoencephalographic responses to spoken arithmetic equations during wakefulness and sleep.

  • levels of CTCs increased at night in humans with breast cancer and mouse models of breast cancer and that CTCs in the rest-phase are more likely to metastasize
  • Cancer cells spread aggressively during the resting phase; however, whether this process occurs during sleep phases, non-rapid eye movement (NREM), or rapid eye movement (REM) sleep remains to be explored.

  • implications for brain plasticity, diseases like autism spectrum disorders, schizophrenia, and dementia, which arise when the brain's networks are not maintained properly, and the ability of the brain to fight off infection and repair the damage following a stroke or other traumatic injury.

      It would be interesting to look deeper into these process and the mechanism behind maintenance of the brain.
  • This research shows that the signals in our brain that modulate the sleep and awake state also act as a switch that turns the immune system off and on."

  • plasticity, the ongoing process by which the complex networks and connections between neurons are wired and rewired during development and to support learning, memory, cognition, and motor function.

      I think it would be cool to look into the difference between this function in people's brains with and without learning disabilities.

  • “Prior research has shown that aircraft noise can elevate stress responses and disturb sleep, but there has been mixed evidence of any links with body mass index,” says study lead and corresponding author Matthew Bozigar, assistant professor of epidemiology at OSU and a former postdoctoral associate at SPH. “We were surprised to see a fairly robust link between aircraft noise and higher body mass index among women across the US.”

      Again, this reminds me of the UCSD juncos and the increased stressors they must endure to live in an urban environment. However, we must remember that just because their emerging population in and around the UCSD campus is successful, it comes with a cost of shorter lifespans, increased mortality, etc. Very interesting stuff.
  • These new findings underscore the role of the environment on one’s risk of chronic disease.
  • Junenette Peters, associate professor of environmental health, and colleagues examined airplane noise exposure and self-reported BMI and other individual characteristics among nearly 75,000 participants living around 90 of the major US airports

  • The team examined aircraft noise levels every five years from 1995 to 2010, using a day-night estimate (DNL) that captures the average noise level over a 24-hour period and applies a 10 dB adjustment for aircraft noise occurring at night, when background noise is low.
  • Although the team acknowledges that BMI is a suboptimal metric, the independent and strong association between more aircraft noise exposure and higher BMI that they observed is notable.
  • “We can only hypothesize about why we saw these regional variations, but one reason may relate to the era of regional development, building characteristics, and climate which may affect factors such as housing age, design, and level of insulation,” says Peters. “Regional differences in temperature and humidity may influence behaviors such as window opening, so perhaps study participants living in the West were more exposed to aircraft noise due to open windows or housing type, which allowed more noise to penetrate.”
  • Previous data suggest that Black, Hispanic, and low-income populations are disproportionately exposed to aircraft noise. The participants in the NHS study groups were primarily White and of mid-level socioeconomic status. 
  • “We need to study the potential health impacts of environmental injustices in transportation noise exposures alongside other environmental drivers of poor health outcomes” Bozigar says. “There is a lot more to figure out, but this study adds evidence to a growing body of literature that noise negatively impacts health.”
