Pyramidal cells in visual cortex

This composite of layer 2 to 3 pyramidal cells in the visual cortex depicts a volley of spikes emerging from the cell bodies and traveling down their axons. The pyramidal cells in the primary visual cortex process visual information received from the retina (via the lateral geniculate nucleus) and begin the task of converting the image into an understandable scene. These cells send their output to other layers within the primary visual cortex, as well as to cells in other parts of the brain.

More about this Image
This still image was derived from animations developed by Greg Hood, John Burkardt and Greg Foss of the Pittsburgh Supercomputing Center. The work contributed to the planetarium show "Gray Matters: The Brain Movie," which debuted in 1999 at the Carnegie Science Center in Pittsburgh, Pennsylvania.

"Gray Matters" was a collaboration among the Studio for Creative Inquiry at Carnegie Mellon University, the Center for the Neural Basis of Cognition and PSC. The work was supported in part by a U.S. National Science Foundation grant (9705491). (Year of image: 1999)
