We humans have a unique capacity to acquire language, even as adults. However, if you have ever used Duolingo, you might have realized that children are more successful at acquiring languages than adults. This observation is puzzling; since adults are smarter than children, shouldn’t it be the other way around? One set of explanations for this paradox focuses on parsing — that is, applying our knowledge of grammar as sentences unfold incrementally…

Potluck of neuroscience: Meet microglia, your brain’s National Guard
![[An illustration of a microglia.]](https://blogs.iu.edu/sciu/files/2021/02/Microglia-Warrior2.png)
One of the first things you’ll learn about if you start studying the brain is that it is made of cells called neurons. While neuroscientists have a decent understanding about how neurons work, it turns out that at least half of the brain is actually made of non-neuronal cells called glia*. Glia, named based on the Greek word for ‘glue,’ were initially thought to be a type of connective tissue in the nervous system, acting just as scaffolding, while the neurons did all the communicating. In the last couple decades, the growing field of neuroimmunology has highlighted the importance of a certain kind of glia: microglia, the brain’s resident immune cells.

In the third part of this blog series, we will finish looking into human consciousness by thinking about what happens to it after death. If you have not seen the episodes, do not worry, spoilers are kept at a minimum! You can read parts 1 and 2 here. San Junipero is a virtual afterlife into… Read more »
Brain technology in Black Mirror: Technological myths or real possibilities? Part II
In the second part of this blog series, we will look at three episodes where proposed technologies involve human consciousness. We will see if these technologies can become real possibilities in the near future. If you have not seen the episodes, do not worry, spoilers are kept at a minimum! You can also read part… Read more »
Brain technology in Black Mirror: Technological myths or real possibilities? Part I
If you happen to watch Black Mirror, it is quite likely that you have been scared by the brain implant technologies depicted in the show. In fact, almost a quarter of this show—at least five episodes of the current 22— illustrate the dangers of brain implants. The horror stories range widely, from transferring someone’s consciousness into… Read more »
What music does to your brain: A neuroscientist’s perspective
Why do we like music? Music is interwoven into almost every aspect of our lives. We hear it at the grocery store and in every single video we watch. We listen to it when we exercise, and we pay boatloads of money to go see our favorite artists in concert. We love all kinds of… Read more »

This is your brain on electricity
In the famous Milgram Experiment, it only took commands from a purported authority figure to get people to subject another study participant to electric shocks up to 450 volts (about a quarter of the voltage used to execute people in the electric chair). In reality, the other participant was an actor, and there were no actual… Read more »
