Tim Dettmers: In this blog post I will delve into the brain and explain its basic information processing machinery and compare it to deep learning. I do this by moving step-by-step along with the brains electrochemical and biological information processing pipeline and relating it directly to the architecture of convolutional nets. Thereby we will see that a neuron and a convolutional net are very similar information processing machines. While performing this comparison, I will also discuss the computational complexity of these processes and thus derive an estimate for the brains overall computational power. I will use these estimates, along with knowledge from high performance computing, to show that it is unlikely that there will be a technological singularity in this century.
Scientists first grew mini-hearts in a lab. Then they 3D printed skin. Now scientists have taken “body on a chip” to a whole new level.

It is now possible to reconstruct spoken sentences from activity patterns of the human brain surface. “Brain to Text” combines knowledge from neuroscience, medicine and informatics.
Researchers from Vanderbilt University are challenging previous hypotheses that changes in restricted areas of the brain were responsible for producing awareness, with evidence that awareness or consciousness results from widespread communication across sensory and association areas of the cortex.

MIT senior, Christina Tringides, holds a sample of the multifunction fiber.
MIT researchers reveal an interface that could make plugging our brain into a computer a reality. Their system uses new fibers less than a width of a hair that could deliver optical signals and drugs directly into the brain, along with electrical readouts to continuously monitor the effects of the various inputs.
Nasal spray could improve memory in people with Alzheimer’s disease.
A new study published in the Journal of Alzheimer’s Disease found that an insulin nasal spray can improve cognitive function in those with Alzheimer’s disease and normal age-related memory problems. The study involved 60 adults who had normal age-related memory problems or mild to moderate Alzheimer’s (Claxton et al., 2015).
The goal of the research was to focus on the target frequencies while ignoring the distractor frequencies.
As we get older, we have an increasingly harder time ignoring distractions. According to new research in the Cell Press journal Neuron, by learning to discriminate a sound amidst progressively more disruptive distractions, we can diminish our distractibility.
