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!

Walking in Nature Stops You from Brooding

If you can manage it, try to go out and walk a bit each day in a large park or other green space (not always easy in poor neighbourhoods. Why? Because yet another study, since the first one by Roger Ulrich in 1984, has confirmed the benefits of natural environments for reducing our tendency to ruminate (focus our thoughts repetitively on negative aspects of ourselves). This new study was done by Gregory Bratman and his colleagues. It is entitled “Nature experience reduces rumination and subgenual prefrontal cortex activation”, and it was published in the journal PNAS in July 2015. (more…)

Are crows just as good at planning as the great apes?

Over the years, many studies have been published on the intelligence of crows, ravens, jays and other corvids (members of the crow family). But according to several specialists on the subject, a study entitled “Ravens parallel great apes in flexible planning for tool-use and bartering,” published in July 2017 in the journal Science, reveals that birds in this family have a heretofore unexpected ability to plan a future behaviour after learning something under experimental conditions. The conditions in this study were such that the behaviour was unlikely to have arisen from a more or less innate adaptation to the birds’ natural environment. The ravens learned to use a rock to get a piece of food out of a box built by humans—certainly not a natural feature of the ecological niche in which their species evolved. Nevertheless, once they had learned this behaviour, they were able to select the rock out of a group of objects, then wait for as many as 17 minutes for the researchers to show them the box again, and then use the rock to get the food out of the box.
