Mirror-image nerve cells, tight bonds between neuron pairs and surprising axon swirls abound in a bit of gray matter smaller than a grain of rice.
‘Hervs’ date back hundreds of thousands of years – and play an important role in regulating genes.
New study could improve the ability to make genetic diagnoses and treat neurodevelopmental disorders.
Those who know Oxford University for its literary luminaries might be surprised to learn that some of the most important reflections on emerging technologies come from its hallowed halls. While the leading tech innovators in Silicon Valley capture imaginations with their bold visions of future singularities, mind-machine melding, and digital immortality by 2045, they rarely engage as deeply with the philosophical issues surrounding such developments as their like-minded scholars over the pond. This essay will briefly highlight some of the key contributions of Oxford University’s professors Nick Bostrom, Anders Sandberg, and Julian Savulescu to the transhumanist movement. It will also show how this movement’s focus on radical autonomy in biotechnical enhancements shapes the wider global bioethical conversation.
As the lead author of the Transhumanist FAQ, Bostrom provides the closest the movement has to an institutional catechism. He is, in a sense, the Ratzinger of Transhumanism. The first paragraph of the seminal text emphasizes the evolutionary vision of his school. Transhumanism’s incessant pursuit of radical technological transformation is “based on the premise that the human species in its current form does not represent the end of our development but rather a comparatively early phase.” Current humans are but one intriguing yet greatly improvable iteration of human existence. Think of the first iPhone and how unattractive 2007’s most cutting-edge technology is in 2024.

Researchers have tested a range of neuroprosthetic devices, from wheelchairs to robots to advanced limbs, that work with their users to intelligently perform tasks.
They work by decoding brain signals to determine the actions their users want to take, and then use advanced robotics to do the work of the spinal cord in orchestrating the movements. The use of shared control — new to neuroprostheses — “empowers users to perform complex tasks,” says José del R. Millán, who presented the new work at the Cognitive Neuroscience Society (CNS) conference in San Francisco today.
Millán, of the Swiss Federal Institute of Technology in Lausanne, Switzerland, began working on “brain-computer interfaces” (BCIs), designing devices that use people’s own brain activity to restore hand grasping and locomotion, or provide mobility via wheelchairs or telepresence robots, using people’s own brain activity.
This is something I wish i had.
Acute mapping of responses to focal electrical neuromodulation in a patient with treatment-resistant depression reveals distinct mood and symptom changes that are highly context dependent.
Simply put, the Hard Problem asks the following question: how can the machinery of the brain (the neurons and synapses) produce consciousness — the colours that we see, for example, or the sounds that we hear?
