The spatiotemporal analysis of brain activation during syllogistic reasoning, and the execution of 1 baseline task (BST) were performed in 14 healthy adult participants using high-density event-related brain potentials (ERPs). The following results were obtained: First, the valid syllogistic reasoning task (VSR) elicited a greater positive ERP deflection than the invalid syllogistic reasoning task (ISR) and BST between 300 and 400 ms after the onset of the minor premise. Dipole source analysis of the difference waves (VSR-BST and VSR-ISR) indicated that the positive components were localized in the vicinity of the occipito-temporal cortex, possibly related to visual premise processing. Second, VSR and ISR demonstrated greater negativity than BST developed at 600–700 ms. Dipole source analysis of difference waves (VSR-BST and ISR-BST) indicated that the negative components were mainly localized near the medial frontal cortex/the anterior cingulate cortex, possibly related to the manipulation and integration of premise information. Third, both VSR and ISR elicited a more positive ERP deflection than BST between 2,500 and 3,000 ms. Voltage maps of the difference waves (VSR-BST and VSR-ISR) demonstrated strong activity in the right frontal scalp regions. Results indicate that the reasoning tasks may require more mental effort to spatial processing of working memory.

Working memory for order information is mediated by different cognitive mechanisms that rely on different neural circuits. Here we discuss evidence that order memory involves mechanisms that range from general supervisory processes to process that maintenance fine-grained temporal position information. We suggest that neural regions-including the prefrontal cortex, motor cortex, parietal cortex and medial temporal structures-operate at different levels and processing stages to give rise to working memory for order information.

Do we need a new criteria for death, that covers the technicalities around neuro preservation, issues of legal identity upon reanimation and an approach to rehabilitation? What are the misunderstandings or misinformation that surround transhumanism and endeavour to make the distinction between transhumanism and technocracy? Should we be worried about the wrong headedness of The Population Bomb, climate catastrophism and the fashionability of long termism?

Today, I speak with Max More. As some of you may already know, Max is considered to be the founder of modern transhumanism, a philosopher and futurist who writes extensively on technology and humanity. He’s also currently ambassador and President Emeritus at Alcor Life Extension Foundation, having served almost 10 years as President and CEO there, and having been its 67th member. His 1995 University of Southern California doctoral dissertation, ‘The diachronic self identity continuity and transformation’, examined several issues that concern transhumanists, including the nature of death. He is the Co-editor of Rhe Transhumanist Reader, and he’s written many articles on transhumanism and extropianism, including the 1990 essay, ‘Transhumanism: toward a futurist philosophy’, in which he introduced the term transhumanism, in its modern sense.

This episode of The Future of You covers:

A deep-space mission is celebrating the first anniversary of its launch from Earth by zipping closer to the planet than the International Space Station’s orbit.

NASA’s Lucy mission launched on Oct. 16, 2021, bound on a 12-year journey to explore the Trojan asteroids, which no spacecraft has ever visited. These asteroids are found at the same distance from the sun as Jupiter, with one phalanx orbiting ahead of the planet and one behind it. All told, Lucy will whiz past nine different asteroids.

The innovative materials, known as thermoformable ceramics, were created by “accident” in a lab but had potential applications, including more effective and long-lasting heat sinks.

The first mission for SpaceX’s newest Dragon crew capsule could hardly have gone more smoothly.

The spacecraft, named Freedom, flew SpaceX’s Crew-4 astronaut mission to the International Space Station (ISS) for NASA, which wrapped up Friday afternoon (Oct. 14) with a splashdown in the Atlantic Ocean off the coast of Jacksonville, Florida.

Text-to-image AI systems such as DALL-E 2, Imagen and Midjourney are growing in popularity and capability right now, offering creators a revolutionary new way to produce content.

Generating images from text prompts is a radical new approach to art-making and creative expression. But it also gives us the first glimpse of a fundamental shift in how we can better communicate and collaborate with our machines. And it is this underlying innovation in human-computer interaction that will disrupt the near-future possibilities for how we are able to work and play.

If we take the Moon’s current rate of recession and project it back in time, we end up with a collision between the Earth and the Moon around 1.5 billion years ago. However, the Moon was formed around 4.5 billion years ago, meaning that the current recession rate is a poor guide for the past.

Along with our fellow researchers from Utrecht University and the University of Geneva, we have been using a combination of techniques to try and gain information on our solar system’s distant past.

We recently discovered the perfect place to uncover the long-term history of our receding Moon. And it’s not from studying the Moon itself, but from reading signals in ancient layers of rock on Earth.
