TAPASI – Monkeys and Microstimulation

Some monkeys and some microstimulation. Courtesy of Gabe Diaz, a little scene from Graziano, Taylor and Moore, 2002. Dots indicate trajectory of the left arm after microstimulation of the right hemisphere PFC. Remember kids – PFC does everything!… Read More

Wasting Time – TheraPutty

Yes, so many other things I could be doing, but this is more important – using a webcam, some Mathematica, and therapy putty. Somehow, as I age, I keep accidentally hurting myself. I know, weird right? So, while… Read More

The Archives of Potentially Amusing Scientific Images (TAPASI)

Why Does the Cortex Reorganize After Sensory Loss?

meh

Investigating the Teleology of Cortical Reorganization A growing body of evidence demonstrates that the brain can reorganize dramatically following sensory loss. Although the existence of such neuroplastic crossmodal changes is not in doubt, the functional significance of these… Read More

Retina and LGN

A demonstration written in Mathematica to show the interaction of the retina and LGN on the sampling of image information from the eyes. You can play with the receptive field size to see how the whole “Hybrid Images”… Read More

VSS 2018 – Shape scission: causal segmentation of shape

Warts, cracks, causal shape segmentation. Research on shape perception usually focuses on the estimation of local surface geometry through cues like stereopsis, shading, or texture. Here, we argue that observers use these shape estimates to infer other object… Read More
