The Conversation #25 — Frances Whitehead

Some of my artist friends think what I’m doing isn’t art, and I’ve giv­en up on art. It’ll take care of itself. You know. I mean it’s always been there, it will always be there, and we always know that new art nev­er looks like art at first, ever. So why should this be any dif­fer­ent? We just have to trust the process. And I would say that must be true for every oth­er discipline.

The Cellular Basis of Neural Computation

Over the past cen­tu­ry, we’ve been to the moon, we’ve split the atom, we’ve sequenced the human genome, but were still only at the very begin­ning of our under­stand­ing of the human brain. This is one of the great chal­lenges that we face. If we can under­stand the brain, we can devel­op bet­ter treat­ments for brain dis­or­ders, we can design bet­ter robots, bet­ter com­put­ers, and ulti­mate­ly we can bet­ter under­stand ourselves.

The Conversation #4 — Colin Camerer

We know very lit­tle about com­plex finan­cial sys­tems and how sys­temic risk, as it’s called, is com­put­ed and how you would man­age poli­cies. And if you look back at the finan­cial cri­sis, you can either say, as many econ­o­mists do, It all had to do with badly-designed rules,” which may be part of the sto­ry; it’s cer­tain­ly part of the sto­ry. Or it may have to do with the inter­ac­tion of those rules and human nature, like mort­gage bro­ker greed, opti­mism… And you see it not just in indi­vid­u­als who now have hous­es and fore­clo­sure, but at the high­est levels.

Controlling the Brain with Light to Reactivate Lost Memories

The key mol­e­cule of opto­ge­net­ics is a light-sensitive pro­tein called chan­nel­rhodopsin, which is extract­ed from green algae. Scientists can insert chan­nel­rhodopsin into mem­o­ry cells. Subsequently, sci­en­tists can even acti­vate these with blue light which they deliv­er deep inside the brain with optic fibers. 

Machines That Can Read Human Emotions

The face is a con­stant flow of facial expres­sions. We react and emote to exter­nal stim­uli all the time. And it is exact­ly this flow of expres­sions that is the observ­able win­dow to our inner self. Our emo­tions, our inten­tions, atti­tudes, moods. Why is this impor­tant? Because we can use it in a very wide vari­ety of applications.

Realizing a Brain on a Chip

If we want to con­tin­ue increas­ing the per­for­mance of our com­put­ers, we need to rethink the way we com­pute. And our brains are won­der­ful proof that impres­sive com­pu­ta­tions can be car­ried out with a very low pow­er budget.

Traditional Medicine Reimagined Through Modern Systems Biology

Why are nat­ur­al com­pounds bet­ter than syn­thet­ic chem­i­cals to treat dis­eases? We have inten­sive­ly ana­lyzed all those known com­pounds in the nat­ur­al prod­ucts, and found that these com­pounds have high­er sim­i­lar­i­ty, espe­cial­ly struc­tur­al sim­i­lar­i­ty, to human metabolites.

Applying Neuroscientific Findings to Enduring Social Problems

When low­er pri­mates form a hier­ar­chy, those at the bot­tom under­go a change in their dopamine sys­tem. This makes them more like­ly to con­sume drugs in an addic­tive fash­ion. Now, if this turns out to be true of our species, that would mean that human beings are par­tic­u­lar­ly vul­ner­a­ble if they’re in some way dom­i­nat­ed or don’t have any power.

Reimagining Everyday Devices as Information-Delivery Systems

What we’re try­ing to think about now is, take the sort of ven­er­a­ble light bulb and recast it as a com­pu­ta­tion­al appli­ance. So, how do we take some­thing that’s been so remark­ably suc­cess­ful and infuse it with com­pu­ta­tion­al abilities?

Looking to Ants to Better Understand Collective Behaviour

How can we extend what we are learn­ing about how sim­ple local inter­ac­tions in ant colonies or in brains, in the aggre­gate, pro­duce the col­lec­tive behav­ior of the group and the way that it responds to chang­ing con­di­tions? How can we extend what we’re learn­ing about col­lec­tive behav­ior in oth­er sys­tems to begin think­ing about col­lec­tive behav­ior in human social organizations?
