Our brains have a limited neural bandwidth in processing incoming information from immediate surroundings. What are possible mechanisms for filtering out unnecessary information? In other words, how do our brains “know” which parts of environment are crucial for us? Priority map theory posits that locations of important elements get special tags, similar to “like” button on Facebook. The more likes a certain location receives for whatever reason – because it is relevant for our current task, for example, or it grabs our attention with a vivid color, the more activity its location elicits in our brain.
This spatial representation of “likes” serves as a map that guides our thoughts and actions to places in immediate surroundings that promise the highest rewards Our brains are not quite helpful like Facebook, unfortunately, and they don’t show the number of “likes”. Or do they? Without any doubt, we need more sophisticated tools to count them, and in order to do that we also need ways manipulate the number of “likes” our posts receive.
To look closer at brain activity, we use functional magnetic resonance (fMRI) and rely on a newly discovered property of occipital and parietal lobes. Under specific experimental conditions we are able to observe topographically organized activity on the surface of the occipital and parietal cortex. It means that the surface activity corresponds to location of important elements occupying contralateral visual field. Thus, when we show salient objects to observers, we can expect to see an increase in cortical activity. The question we are trying to answer is how the number of “likes” we observe corresponds to importance of presented items. In addition, what if we show multiple items in the same time? Tortilla chips are great, but if you could also get ice cream, what would you choose?
The choice between ice cream and tortilla chips might seem trivial to some of us, but when you think about it, many everyday decisions rely on judging relative importance of available options. Importantly, attention disorders such as autism or attention deficit hyperactivity disorder (ADHD) could affect, among others, the ability to filter out important environmental cues and choose priorities. Combining in our experiments observation of brain activity and eye movements we want to uncover at least a small part of the Facebook machine.
