Two new studies show that the brain’s navigation system changes how it represents physical space to reflect personal experience.

A brain implant that registers trauma could help prevent rape and violent crime — so why don’t we have it yet?
SXSW: These two futurists want to freeze your body after death and replace your brain
You might think we’re not in Texas anymore but in some strange episode of Black Mirror, the Netflix series, says Nikos Acuna who is moderating this SXSW panel on transhumanism.
In fact you’d be forgiven if you did as there is talk about cryo-preserving the body after being declared dead, in the hopes you can be resurrected when the science is here to safely defrost your body and cure you of your ailments. There is also talk on mind uploading, and replacing parts of our brains with neural prosthetics. This all sounds like science-fiction but these days the stuff of science fiction has become fact.
Transhumanist technologies are about overcoming the limitations of human biology and Dr Max More and Dr Randal Koene are at the forefront of these technologies.

For fifteen years, I’ve assumed that the Matrix Sequels were irredeemable failures. But looking back on them with fresh eyes reveals a pair of films that are exhilarating, interesting, and sometimes hilarious. In this video I try to make sense of these two movies, and what they have to say about free will and the systems that control society.

3 Reasons Why “Ending Suffering” Should Be the #1 Transhumanist Priority – Article
BY HANK PELLISSIER
Hank Pellissier
Editor’s Note: The U.S. Transhumanist Party / Transhuman Party features this proposal by our member Hank Pellissier for a new website called Paradise2040, which will focus on the abolition of involuntary suffering and incremental ways of getting there within the next 21 years. This is an endeavor supported by Article IV of the Transhumanist Bill of Rights, Version 3.0. It is also a current within transhumanist thinking that, as Mr. Pellissier points out, could bring additional support to the movement. Different transhumanists will have different views as to what the most important aims of transhumanism should be. As an organization that embraces pluralism and diversity of thought, the U.S. Transhumanist Party / Transhuman Party would encourage any of our members who agree with the direction Mr. Pellissier proposes to collaborate with him on the creation of the Paradise2040 website.

A survey I conducted in 2010 of 818 transhumanists identified “brain enhancement” as the #1 priority, with “maximizing” health and life extension as #2 and #3. The top three “values” of the U.S. Transhumanist Party (the Core Ideals) are #1) Life Extension, #2) “a cultural, societal, and political atmosphere informed and animated by reason, science, and secular values”, and #3) “to reduce and eliminate existential risks.”
Graphene-based brain implant reveals secrets inside the brain
A new graphene-based brain implant could help provide information about the onset and progression of epileptic seizures and pave the way for next generation brain-computer interfaces.
The new implant, which records electrical activity in the brain over large areas and at frequencies below 0.1Hz, is said to overcome the limitations of electrode arrays that have only been able to detect activity over a certain frequency threshold.
The technology was developed by Graphene Flagship partners at the Barcelona Microelectronics Institute (IMB-CNM, CSIC), the Catalan Institute of Nanoscience and Nanotechnology (ICN2), and ICFO.
Adult hippocampal neurogenesis is abundant in neurologically healthy subjects and drops sharply in patients with Alzheimer’s disease

The hippocampus is one of the most affected areas in Alzheimer’s disease (AD). Moreover, this structure hosts one of the most unique phenomena of the adult mammalian brain, namely, the addition of new neurons throughout life. This process, called adult hippocampal neurogenesis (AHN), confers an unparalleled degree of plasticity to the entire hippocampal circuitry3,4. Nonetheless, direct evidence of AHN in humans has remained elusive. Thus, determining whether new neurons are continuously incorporated into the human dentate gyrus (DG) during physiological and pathological aging is a crucial question with outstanding therapeutic potential. By combining human brain samples obtained under tightly controlled conditions and state-of-the-art tissue processing methods, we identified thousands of immature neurons in the DG of neurologically healthy human subjects up to the ninth decade of life. These neurons exhibited variable degrees of maturation along differentiation stages of AHN. In sharp contrast, the number and maturation of these neurons progressively declined as AD advanced. These results demonstrate the persistence of AHN during both physiological and pathological aging in humans and provide evidence for impaired neurogenesis as a potentially relevant mechanism underlying memory deficits in AD that might be amenable to novel therapeutic strategies.
Hacking The Brain: The Future Computer Chips In Your Head
Over the past twenty years, neuroscientists have been quietly building a revolutionary technology called BrainGate that wirelessly connects the human mind to computers and it just hit the world stage. Entrepreneurs such as Elon Musk and Mark Zuckerberg have entered the race with goals of figuring out how to get computer chips into everyone’s brains. The attention of Musk and Zuckerberg means the potential for giant leaps forward. But the question no one seems to be asking is whether our dependence on machines and technology has finally gone too far. Countries annually celebrate their independence from other countries, but it now seems we should start asking deeper questions about our personal independence.
60 Minutes recently ran a piece showing how engineers are using what scientists have learned about the brain to manipulate us into staying perpetually addicted to our smartphones. The anxiety most of us feel when we are away from our phone is real: During the 60 Minutes piece, researchers at California State University Dominguez Hills connected electrodes to reporter Anderson Cooper’s fingers to measure changes in heart rate and perspiration. Then they sent text messages to his phone, which was out of his reach, and watched his anxiety spike with each notification.
The segment revealed that virtually every app on your phone is calibrated to keep you using it as often and as long as possible. The show made an important point: a relatively small number of Silicon Valley engineers are experimenting with, and changing in a significant way, human behavior and brain function. And they’re doing it with little insight into the long-term consequences. It seems the fight for independence has gone digital.
