    I recommend the book Gesture and Speech by Leroi-Gourhan, page 154 " cerebral evolution of the neantropics " , Is an anthropological and also archaeological point of view, he introduce the prefrontal cortex as the main reason for hour conscience. I also recommend the work of Searle and his research on the Conscience , he is a pioneer to bringing the biological study of conscience in the academy system

    Not sure where this was filmed but I would be down to skateboard the pool in the background. Excellent conversation as usual, thank you.

    great interview:

    Funny thing is like computer hardware used to be all seperate with the CPU with one specific task & the GPU only handling another. But today it's the GPU that is asked to be used for computational tasks along with the CPU & vice versa than there's a system on a chip that again has seperate compartments that do communicate interactively similar to the ways parts of the brain does.

    Plus, parts of a damaged human brain can rewire parts of itself to be able to relearn similar tasks now done with parts of the brain that was assumed to do. I believe there's much overlapping skills inside different parts of the brain.

    My belief in regards to non human animals is we're all alive, we feel pain with our nervous systems, we have hunger, thirst, sex. All sharing basic consciousness per se.

    i don't believe animals are sitting there relaxed one day dreaming of creating music, paintings or literature.

    contemplating its goals in the next 5, 10 years time frame.

    but we do see animals beyond just survival have the exact same "playing" capabilities humans have. we've seen dogs & cats playing piano for 1/2 hour. watch elephants grab a paint brush & draw images on a canvas.

    Funny, the more & more computer programs accomplish similar domains we thought were purely only human like ability to play chess or jeopardy well enough to win is teaching us to think differently about "intelligence" & "consciousness" per se. it's not turning out to be black & white but more gray areas like the brain is 🙂

    What i find interesting isn't so called "intelligence" or "thinking" because simple & complex computers have mimicked that today.

    Humans have a certain number of thoughts per day. About survival needs, future planning & past memories etc.

    I'd like to know or describe what the brain is doing when we aren't thinking & just being.

    What is the brains purpose or function when in between our thoughts?

    when I meditate & go from 100 thoughts a minute to one thought an hour. what is the brain doing for that one hour while I didn't have any or a few random thought?

    The brain still has "intelligence" when it's not thinking, right?

    Today's brain probes & hardware can only record when we're thinking or imagining a glass of water.

    I wonder what it can show as to what the brain is doing in between actual images & thoughts?

    It's call Zen moments or Flow.

    Being in the Flow basically turns off all outside noisy distractions allowing one to simply be, focusing on task at hand in the moment etc.

    love the phrase- "I think, therefore I am"

    So, if I don't think therefore I am not? LOL

    being from eastern europe, when you say Lex Fridman withouth the "i"( how you hear, not how you write it) it was strange to understand what do you mean .. I always forget this strange thing in english when they say "i" and they refer to "e" and when they say "ei" and the refer to "a" or "i" ?!

    how can he take so long to answer whether animals have a PFC at around 47:00 thats an indisputable "yes"-fact about anatomy of nervous systems in mammals, not "open questions" at 49:00

    Stop me if you've heard this before: I used to think that the human brain was the most fascinating part of the body, then I realised, look who's telling me that.
    Thanks heaps for this, science graduate in psychology, inspiring me to work harder to get to that next level.

    I Saw an ad seconds after you finished your intro ad, after the talk had started, and just saw another around 14-15 minutes in… I really hate ads while watching something, and totally don't mind yours at the beginning, but not while the conversation is going on… (don't know if there's more yet… but seems likely..)

    If only the encoding potential of a neuron is relevant then the mind emerges only from the abstraction of the information the neurons encode, if it is only software, not tied to the underlying physical structures then it exists in an abstract not physical space.

    Do you think there is an infinite (or extremely large) descent kind of analysis required in neuroscience? In physics we can always reason all the way down to the atoms, but in neuroscience we are trying to explain why certain combinations of atoms are acting in concert. This transforms a problem space from just the physical space into a larger "combinatorial" space (2^(Number of Atoms in a Brain))

    That's nice that engineers ask themselves the goal of their research. The problem I see, however, is that the company they work for can decide for them.

    @Lex, I have a question for you. Before that, thank you so much for doing this. Matt layed out the top down and bottom up approaches in AI-Cogntion-Neuroscience. What do you personally believe? To give you my opinion, as Joscha said in your other interview, if there are things being built then let them build it. Even François for that matter said, L5 is something which is very hard to achieve and they are sticking to the vision, as in the deep learning part of it to begin with and I believe, as he mentioned in his paper, it is going to be system centric generalization at first (hopefully) anyway. What if the bottom up approach can contribute effectively to this mutually exclusive domains in broader terms. What do you personally believe or think considering you staying at the AI end of it?
