Can you pay attention to the movie, or do you just hear people chomping on popcorn? Image credit: hashi photo (Wikimedia Commons)
At any given moment, we are constantly bombarded by signals from at least four of the five senses.
The visual system is constantly processing our surroundings. The auditory system is stimulated by all of the many miniscule sounds that compose our environment. We’re taking in all the smells around us at any given moment, and we’re constantly feeling the clothes on our skin. Even within one sensory system, there is an enormous amount of data that gets processed.
With this onslaught of input, how do we manage to not go completely insane? The key is that we pay attention to only a small proportion of that information and throw much of it away. This process is known as selective filtering or selective attention, and most people do it all the time. Image watching a movie at a theater; if you’re quite focused on the film, you’re probably not noticing the sound of squeaking seats, crunchy popcorn, or even the air conditioning whirring through the vents.
Although there are several regions of the brain involved in each sensation, the part of the brain involved in selective filtering is where all of these senses intersect.

In this fifth and final post of the War on Cancer series, I will discuss the future of cancer treatment. I will also tie in my previous posts of the series, which include:
- How Can We Win the War on Cancer?
- Targeted Therapy
- Tumor Relapse
- Tumors as Ecological Systems
As I mentioned in Part 1, cancer is not one disease, but thousands, and these thousands of different diseases evolve as time goes on. Current treatments have improved greatly over the years, meaning people with cancer are living longer than ever before. New ways of treating cancer, however, will be needed to ultimately cure it.
Current research suggests that there will likely be three stages to the future of treatment: (1) discovering more vulnerabilities to target, (2) quickly mapping the genetic profile of individual tumors, and (3) developing drugs that will not only combat a tumor, but keep it from relapsing.

Scientific conferences are an important way to learn about the latest developments in your field and to meet people who can help you advance your career. They are annual meetings organized by professional societies that include poster presentations, oral presentations, and social events. Conferences often take place in major cities (like San Diego, Washington DC, or Chicago), though the location of each conference usually changes from year to year. Conference attendees include professors, medical doctors, industry representatives, graduate students, and occasionally undergraduate students.
Conferences can be a lot of fun, but they can also be intimidating and overwhelming! I attended my first two conferences this year – Animal Behavior Society (ABS) in August and Society for Neuroscience (SfN) in November.
Here are a few tips and tricks that I hope can help you survive (and thrive) at a scientific conference:
