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!

Seeing What’s in Your Eye

The structure of your eye is a lot like that of a traditional film camera. The lens of your eye is like the camera’s lens. Your iris is like the diaphragm, and your retina, at the very back of the eye, acts like the light-sensitive film.

However, there is a hole in your retina that lets the axons of its ganglion cells (a kind of neuron) exit the eye while letting blood vessels enter to irrigate all of the retina’s neurons. This hole creates a true “blind spot” in your field of vision. You don’t notice this blind spot in your daily life. (more…)
