G2C Online



In Nature Neuroscience this February, Bickart et.al. demonstrate a correlation between the number of friends you have and the size of your amygdala . Specifically, they showed that the volume of the amygdala is positively correlated with the size and complexity of a person’s social network.

As stated on the G2C website, the amygdala is involved in processing emotions, and fear–learning. Concerning the amygdala and fear, the flight-or-flight response is one of the most well known examples. So do people with more “frenemies” have larger amygdalae to help them survive inevitable back stabbing?

According to this paper, while there was a correlation between large More >


Overcoming Fear

We all fear things. Fear itself is a basic survival instinct. It’s a natural response to a specific stimulus used to recognize danger and initiate fight-or-flight responses. Many common fears include ghosts, cockroaches, spiders, snakes, heights, water, enclosed spaces, tunnels and bridges, needles, exams, clowns and public speaking. These fears can be innate (you don’t know why you’re afraid of certain things) or they can be acquired by a frightening traumatic accident. For many people, their fears do not affect their quality of life. For some, however, fear can mean something completely different.

Sports and Concussions

We have all heard of concussions, but it seems to be not until recently that concussions are finally taken seriously. Many of our popular sports contain some sort of contact. Football is a very popular sport with many times, full contact. What about other sports such as boxing or mixed martial arts where contact, especially head contact is deliberate? Or in NASCAR’s car accidents involving vehicles traveling close to 200mph? Athletes are putting their brains on the line for their sport.

Over the past several years, many precautions were taken to prevent concussions and further damage to the brain following injury. More >


A Willingness to Donate? It May Be in Your DNA

Okay, I’ve come to terms with the fact that Christmas is coming soon. It seems to have snuck up fast (although I’m beginning to think that it does that every year.) Once November started, Santa set up shop taking pictures in the middle of the mall. This is the time of giving gifts and receiving gifts. It’s the time of rushing to the store, and trying to beat closing time to get the last minute gifts (after finally figuring out what to buy to begin with). It’s the time of wonderfully smelling houses with more food cooking than what could More >


The Mystery of Autism

Calling Autism a disorder is a bit misleading. The term “Autism” is really a category for a spectrum of disorders including Autistic disorder, Asperger syndrome, Childhood Disintegrative disorder, Rett syndrome, and Pervasive Developmental disorder. Those afflicted with these disorders often share difficulties in communication and social interactions. Some cannot speak or maintain eye contact. Some have repetitive routines and an obsessive attention to certain details. In the United States, an estimated 1 in 110 children has an autism spectrum disorder and for the past several years, it’s been on the minds of many researchers around the world.
