After providing all the funding for The Brain from Top to Bottom for over 10 years, the CIHR Institute of Neurosciences, Mental Health and Addiction informed us that because of budget cuts, they were going to be forced to stop sponsoring us as of March 31st, 2013.

We have approached a number of organizations, all of which have recognized the value of our work. But we have not managed to find the funding we need. We must therefore ask our readers for donations so that we can continue updating and adding new content to The Brain from Top to Bottom web site and blog.

Please, rest assured that we are doing our utmost to continue our mission of providing the general public with the best possible information about the brain and neuroscience in the original spirit of the Internet: the desire to share information free of charge and with no adverstising.

Whether your support is moral, financial, or both, thank you from the bottom of our hearts!

Will You Be the Same Person in 10 Years As You are Now?

Our thought processes are far from being as reliable and logical as we often think they are. In reality, our brains are constantly playing tricks on us, ranging from simple optical illusions to change blindness and other cognitive biases to the illusion that the self is a continuous entity that has the experiences that make up our lives.

Scientists are discovering more and more ways in which the brain fails to operate according to the simple common sense that we would expect. One notable example is the way that we perceive ourselves over time. In this regard, a study published in the January 2013 issue of the journal Science revealed a truly strange phenomenon that the authors call the “end of history illusion”—a reference to a concept originated by the German philosopher Hegel and advanced by American thinker Francis Fukuyama in a controversial 1992 book arguing that humanity had reached the end point in its sociocultural evolution.

Science Starting To Identify the Molecular Bases of the Sense of Touch

When it comes to senses such as vision, scientists have known for some time which molecules are responsible for transduction—the conversion of physical stimuli into nerve impulses. Until recently, however, the molecular bases of the sene of touch remained ill-defined. But in an article first published online in the journal Nature in December 2012, Dr. Zhiqiang Yan and his research team from the University of California at San Francisco (UCSF) reported having found what they believed was the missing link in transduction for the sense of touch.

The Various Speeds at Which We Perceive Time

Our perception of how fast time passes is amazingly subjective. When we are children, our summer vacations from school seem to stretch on forever. When we are grownups, we are often surprised to realize how long it has been since some major event occurred—Hurricane Katrina was over eight years ago, and the nuclear disaster at Chernobyl almost 28 years ago!

Thus we frequently underestimate or overestimate elapsed time. But what are the factors that push our estimates in one direction or the other? Are there some time scales that are affected and others that are not? Are there certain areas of the brain that are associated with the way we estimate time? (more…)
