Microsaccades: Our Visual Framerate
Dr. Frank Werblin at UC Berkeley has dedicated nearly his entire academic life to the study of the eye and visual processing. More recently Dr. Werblin has completed his model of the retinal processing system he has deemed “The Retinal Hypercircuit”. The Hypercircuit itself is made up of the five classical retina cell types: Photoreceptor, […]
Insights from a Failing Brain
For years, scientists have investigated cases of human brain damage as a means of further understanding the function of specific neural regions, but neuroanatomist, Dr. Jill Bolte Taylor, received the unique opportunity of experiencing this function-impeding damage firsthand. She awoke one morning to find herself having a stroke, and years later has recovered to share […]
A.I. in the "Cloud"
The world seems as though it is starting to move faster and faster, and thus the demand for information and information accessibility is drastically speeding up as well. Modern computers and related technologies, however, have done a remarkable job with both creating and keeping up with the ever growing demand for data and access people […]
The Hard Problem of Consciousness
You’re lying on a sandy beach on a hot sunny afternoon, enjoying a few hours of much needed laziness. As you open your eyes and confront the vastness of the ocean in front of you, light of 600nm wavelength hits your retina, kindling an impossibly long cascade of events in your brain: a molecule called […]
Middle World
A little self-education goes a long way. Let Richard Dawkins enlighten you (and if you’ve seen this already, it’s never a bad idea to brush up on the basics of life):
“Avatar" Virtual Reality: Scientists Explore Self-Consciousness
In the 2009 film Avatar, scientists exploring the planet Pandora used alien hybrid bodies called “avatars” that functioned through a mental connection established with their genetically-matched human counterparts. While this kind of technology seems as science fictionally fantastic as only the movies can portray it, recent work in the neuro-scientific community may lead the world to […]
Scientific Misinformation
Stuart Hameroff, MD, is an anesthesiologist and professor at the University of Arizona. In one of many articles and videos about consciousness on the Huffington Post, Hameroff describes how anesthesia can help explain consciousness. If the brain produces consciousness (all aspects of the term), then it seems to follow that turning off the brain will […]
Replacing Neurons
Imagine: a mad scientist with a ray gun shoots at a neuron somewhere in cortical layer IV of your visual area MT, burning it up in a matter of microseconds (just for fun, imagine also that the ray gun leaves everything else intact). With one neuron missing, you probably won’t notice any perceptual change. But what […]
