Hey there, reader! This is the first in a series of articles addressing common myths about the brain. You can find my previous article here, in which I discuss the complexity of depression. Expect more to be coming soon! Enjoy reading.

Imagine eating a jelly donut. Imagine your first kiss. Imagine getting a good performance review from your boss. In each case, you may feel a sense of happiness, joy, or pleasure. Now, think about the brain functions that cause these happy feelings. You might guess that each of these scenarios triggers an instant boost of dopamine and serotonin in your brain. Dopamine and serotonin are two of the most talked about (and two of the most misunderstood) neurotransmitters, the chemicals that brain cells use to communicate. Yes, dopamine is associated with pleasure and serotonin with mood, but to stop there would be missing the full picture. Like many myths, there is some truth here. However, these molecules have a much richer role in the body and behavior than just the happy feelings.

Placebo or Nocebo?

Last year, when I pooh-poohed my mother’s alternative medicine regimen, she said, “But these actually work well for me, because I believe in them!” My mother had just outsmarted me with science.

The placebo effect is one of the most remarkable yet least understood phenomena in science. It is a favorable response of our body to a medically neutral treatment (sugar pills, anybody?): in other words, a placebo is a fake treatment that produces a very real response. This is attributed to a physical reaction stemming from a psychological response to the administration of therapy. You could say that a patient sometimes gets better anyway—how many times have we waited out the common cold—and you would be right. This natural return to the baseline which can happen is not considered the placebo effect, which is an improvement in response to a treatment.

In my last post, I wrote about the social differences between introverts and extroverts and the misconceptions surrounding the two personalities. This post will focus on the underlying brain biology that contributes to whether a person is an extrovert or an introvert.

The more I read about these personalities, the more I wondered—are there ways in which the biology can explain the social differences? It turns out that there are several known, key differences in the brain biology between introverts and extroverts.

Introverts & Extroverts: It’s Not as Simple as Shy or Outgoing (Part 1)

Seemingly every Friday night, I’m curled up on my couch with a glass of wine and a good movie. Yet, it amazes me how many people scoff or flat-out laugh when I tell them that I’m an introvert. I am! In social situations, my mood can change very suddenly. It’s as if my social batteries have run out, flipping my social switch from on to off. Such changes are confusing for my friends, which might be based on the big misconception surrounding introversion and extroversion in society.
