Neuroplasticity and the Fire-Wire Principle

In an earlier post I introduced the idea that neurons that fire together wire together. When we experience a habitual simultaneity between two things, the part of the brain that responds to those two things becomes fused. The reason this it’s possible for this to happen because the brain is plastic, in the sense of being adaptable and malleable. (We discussed the phenomenon of neuroplasticity earlier in our posts ‘From Localizationism to Neuroplasticity’ and ‘The Adaptive Brain.’) Continue reading

Neurons That Fire Together Wire Together

Our last post looked at the power that associations have in organizing experiences presented to our brains, and we considered the phenomenon of smell as one example of this. We saw that if certain things are associated with pleasant or unpleasant experiences, then those things can actually become pleasant or unpleasant to our brains through the power of association.

The Power of Association

In our earlier post ‘The Eroticism of Odor‘, we looked at the strange (to us) custom of other cultures to actually prefer the smell of body odor, especially that of the opposite sex. We saw how it was typical for a woman to put apple pieces under her arm and, after it had absorbed her scent, offer it as a gift to her boyfriend.

There’s a good reason why other societies have felt like this about BO and why we don’t, and it gives us insight into an important feature of the human brain that we will be discussing in a series of posts over the next few months.

The reason has to do with the power of associations. Having largely banished body odor from Western society, we now associate the body’s natural smell with uncleanness and lack of hygiene. But put yourself back in Elizabethan times. In their pre-deodorant society, the smell of the body was normal, because that is what they were used to. Moreover, it could even be pleasant because that was the smell you associated with being in the presence of the person you love.

Don’t worry, this is not a plea for a new naturalism. I am not about to embark on a campaign to eliminate deodorant from our society. However, I mentioned the above facts because it leads into a theme I wish to spend some time unpacking, which is the power associations have in ordering our brains.

Put simply, if certain things are associated with pleasant or unpleasant experiences, then those things can actually become pleasant or unpleasant to our brains through the power of association.

Even today there are more subtle body odors that can only be perceived if we are in close proximity with a naked member of the opposite sex, which means that such odors tend to be associated with sex—an association that renders certain smells pleasant to us because of the power of association, though this process usually happens on an instinctive level far beneath the conscious mind.

Study Skills for Psychology Licensing Prep – Overview of Series

Over the past few months, I’ve been sharing some of the ways you can improve your online study skills in your psychology licensing prep. The suggestion I’ve offered have been rooted in the latest advances in brain science, including some discoveries that are still considered cutting-edge. Now that we’ve completed running that series, it may be helpful to summarize the ground we’ve covered and provide a complete list of links for future reference.

We opened the series with our post ‘Online Learning: The Way of the Future.’ This article looked at some of the important shifts that have occurred in the history of the university, culminating in the rise of online education. We suggested that, as with other changes in the past, special skills are required to maximize the benefits of the new tools available to students.

Be Careful How You Train Your Brain

During your ‘time off’—that is, during the times when you are not studying for the EPPP—be careful how you treat your brain.

Just as an Olympic athlete will take care of his body even during the times of the day when he is not training or competing, so a student should take care of his mind even during those times of the day when he or she is not actually studying.
