HDIAC Podcast — Weaponizing Brain Science: Neuroweapons — Part 1 of 2

Posted by in categories: chemistry, neuroscience, science, security

https://www.hdiac.org/podcast/neuroweapons-part-1/

In part one of this two-part podcast, HDIAC analyst Mara Kiernan interviews Dr. James Giordano, a Professor in the department of Neurology and Biochemistry at Georgetown University Medical Center. The discussion begins with Dr. Giordano defining neuroweapons and explaining their applied technologies. He provides insight into the manner in which international weapons conventions govern the use neuroweapons and discusses the threats presented by neuroweapons in today’s environment. Dr. Giordano goes on to review the need for continuous monitoring, including his views regarding challenges and potential solutions for effectively understanding global developments in neuroweapon technologies.

Researchers discover mechanism for memory storage in engram cells

Posted by in category: neuroscience

What is the mechanism that allows our brains to incorporate new information about the world, and form memories? New work by a team of neuroscientists led by Dr Tomás Ryan from Trinity College Dublin shows that learning occurs through the continuous formation of new connectivity patterns between specific engram cells in different regions of the brain.

Whether on purpose, incidentally, or simply by accident, we are constantly learning and so our brains are constantly changing. When we navigate the world, interact with each other, or consume media content, our brain is grasping information, creating new memories.

The next time we walk down the street, meet our friends, or come across something that reminds us of the last podcast we listened to, we will quickly re-engage that memory information somewhere in our brain. But how do these experiences modify our neurons to allow us to form these new memories?

How do two new books on consciousness close in on the elusive field?

Posted by in categories: evolution, neuroscience

The Four Realms of Existence by Joseph LeDoux and Consciousness by John Parrington tell us a lot about human cognition, brain structure and evolution – but most of all they demonstrate how far this most tricky of quests still has to go.

Bayesian encoding and decoding as distinct perspectives on neural coding

Posted by in category: neuroscience

This paper characterizes two distinct philosophies underlying previous work on how Bayesian computations are linked to neural data, highlighting how different theories may be motivated by different tacit assumptions and thereby explain different data.

Neuralink, Elon Musk’s brain implant startup, quietly raises an additional $43M

Posted by in categories: computing, Elon Musk, finance, neuroscience

Neuralink, the Elon Musk-founded company developing implantable chips that can read brain waves, has raised an additional $43 million in venture capital, according to a filing with the SEC.

The filing published this week shows the company increased its previous tranche, led by Peter Thiel’s Founders Fund, from $280 million to $323 million in early August. Thirty-two investors participated, according to the filing.

Neuralink hasn’t disclosed its valuation recently. But in June, Reuters reported that the company was valued at about $5 billion after privately-executed stock trades.

The neuropeptidergic connectome of C. elegans

Posted by in categories: biotech/medical, neuroscience

An amazing graph theoretic analysis of the C. elegans neuropeptide connectome!


Neuromodulation by peptides is essential for brain function. By comprehensively mapping neuropeptide signaling in the nematode C. elegans, Ripoll-Sánchez et al. define a dense wireless network whose organization differs in important ways from wired brain circuits. This network is a prototype for understanding neuropeptide signaling networks in larger brains.
