In a computational reconstruction of brain tissue in the hippocampus, Salk and UT-Austin scientists found the unusual occurrence of two synapses from the axon of one neuron (translucent black strip) forming onto two spines on the same dendrite of a second neuron (yellow). Separate terminals from one neuron’s axon are shown in synaptic contact with two spines (arrows) on the same dendrite of a second neuron in the hippocampus. The spine head volumes, synaptic contact areas (red), neck diameters (gray) and number of presynaptic vesicles (white spheres) of these two synapses are almost identical. (credit: Salk Institute)

Salk researchers and collaborators have achieved critical insight into the size of neural connections, putting the memory capacity of the brain far higher than common estimates. The new work also answers a longstanding question as to how the brain is so energy efficient, and could help engineers build computers that are incredibly powerful but also conserve energy.

In the early days of the space race of the 1960s, NASA used satellites to map the geography of the moon. A better understanding of its geology, however, came when men actually walked on the moon, culminating with Astronaut and Geologist Harrison Schmitt exploring the moon’s surface during the Apollo 17 mission in 1972.

In the modern era, Dr. Gregory Hickock is one neuroscientist who believes the field of neuroscience is pursuing comparable advances. While scientists have historically developed a geographic map of the brain’s functional systems, Hickock says computational neuroanatomy is digging deeper into the geology of the brain to help provide an understanding of how the different regions interact computationally to give rise to complex behaviors.

“Computational neuroanatomy is kind of working towards that level of description from the brain map perspective. The typical function maps you see in textbooks are cartoon-like. We’re trying to take those mountain areas and, instead of relating them to labels for functions like language, we’re trying to map them on — and relate them to — stuff that the computational neuroscientists are doing.”

At one time or another, we’ve all been encouraged to “maximize our potential.” In a recent interview, Academic and Entrepreneur Juan Enriquez said that mankind is making progress toward expanding beyond its potential. And the changes, he believes, could be profound.

To illustrate the process, Enriquez theorized what might happen if we were to bring Charles Darwin back to life and drop him in the middle of Trafalgar Square. As Darwin takes out his notebook and starts observing, Enriquez suggested he would likely see what might appear to be a different species. Since Darwin’s time, humans have grown taller, and with 1.5 billion obese people, larger. Darwin might also notice some other features too that many of us take for granted — there are more senior citizens, more people with all their teeth, a lot fewer wrinkles, and even some 70-year-olds running in marathons.

“There’s a whole series of morphologies that are just different about our bodies, but we don’t notice it. We don’t notice we’ve doubled the lifespan of humans in the last century,” Enriquez said. “We don’t notice how many more informations (sic) come into a brain in a single day versus what used to come in in a lifetime. So, across almost every part of humanity, there have been huge changes.”

Part of the difference that Darwin would see, Enriquez noted, is that natural selection no longer applies as strongly to life and death as it once did. Further, random gene mutations that led to some advantages kept getting passed down to generations and became part of the species. The largest difference, however, is our ongoing move toward intelligent design, he said.

This came up recently and it occurred I never posted this here. This is a lecture by Robert Bradbury, not not Ray Bradbury. I had the pleasure of exchanging a few emails with him. Unfortunately those emails are lost so I cannot share them. He was an advocate of life extension and he was a big thinker. I’ll post both vids and a link to the M-brain page. He is not with us anymore I regret to say. Ready?

Renown aging expert Robert Bradbury discusses whole genome engineering, evolution and aging and ways to defeat aging. His talk touches on many areas including nanotechnology, biology, and computer science.

Optogenetic laser light stimulation of the thalamus (credit: Jia Liu et al./eLife)

By flashing high-frequency (40 to 100 pulses per second) optogenetic lasers at the brain’s thalamus, scientists were able to wake up sleeping rats and cause widespread brain activity. In contrast, flashing the laser at 10 pulses per second suppressed the activity of the brain’s sensory cortex and caused rats to enter a seizure-like state of unconsciousness.

“We hope to use this knowledge to develop better treatments for brain injuries and other neurological disorders,” said Jin Hyung Lee, Ph.D., assistant professor of neurology, neurosurgery, and bioengineering at Stanford University, and a senior author of the study, published in the open-access journal eLIFE.

US army’s report visualises augmented soldiers & killer robots.

The US Army’s recent report “Visualizing the Tactical Ground Battlefield in the Year 2050” describes a number of future war scenarios that raise vexing ethical dilemmas. Among the many tactical developments envisioned by the authors, a group of experts brought together by the US Army Research laboratory, three stand out as both plausible and fraught with moral challenges: augmented humans, directed-energy weapons, and autonomous killer robots. The first two technologies affect humans directly, and therefore present both military and medical ethical challenges. The third development, robots, would replace humans, and thus poses hard questions about implementing the law of war without any attending sense of justice.

Augmented humans. Drugs, brain-machine interfaces, neural prostheses, and genetic engineering are all technologies that may be used in the next few decades to enhance the fighting capability of soldiers, keep them alert, help them survive longer on less food, alleviate pain, and sharpen and strengthen their cognitive and physical capabilities. All raise serious ethical and bioethical difficulties.

“Inhuman: The Next & Final Phase of Man is Here” is not fiction or a mockudrama but a new investigative documentary from Defender Films and Raiders News Productions.

Inhuman travels the globe to unveil for the first time how breakthrough advances in science, technology and philosophy—including cybernetics, bioengineering, nanotechnology, machine intelligence and synthetic biology are poised to create mind-boggling game changes to everything we have known until now about Homo sapiens.
