The snake problem is great. Tons to chew on there. What a great example for the discussion of experimental design. Thanks to Dr. Kanwisher and MIT for publishing this.

1. A very good control condition for snake photo is as prof stated, tree branch lying on ground. Coming from snake country, i would often be running in nature, including mountain elevations, when i would jump away from such a small branch, years later. 2. Baseline rate is best tested before and after the stimulus run. Some differences in area arousal, if occurring; and possible opposing information, through which to learn limit of specificity more closely. 3. DMN is internal focus, but research has shown that individuals vary in rumination. For some DMN rumination is social, arousing competitive , resentment, and other negatively valenced thoughts. Others may be relaxed during DMN, visualizing either more pleasant reverie, or planning. DMN , can vary, with its only commonality absence of significant sensory or motor activity, though it may vary if imagining motor activity. (and the huge roar of rotating MR generator eliminates any real baseline normality of brain activity, anyway, unless very insulating earphones) So, baseline is best created with researcher instruction to perform a specific mental activity.

My auto-associative memory is off the charts. And it has much to do with counting without numbers or drawing without knowing what I’m drawing perfectly sideways. It’s like an engine being systemized and it can churn particular “calculations” without me determining it’s going to tackle that problem.

Stimulating V1 nothing happens, maybe a flash of light… and what about An out-of-body experience was repeatedly elicited during stimulation of the posterior part of the superior temporal gyrus on the right side?

[@aaronwilson9763]

Here's an interesting question: Why do animals such as dogs, cats, and monkeys seem to look humans in the face...I mean not just the face, but always with eye contact? This thought is kind of creepy...are they trying to read or interpret some form of emotional context? I'm loving this MIT channel on KZbin...it's adding a lot of value to the KZbin experience! Thanks for sharing!

[@nujranujranujra]

that's really a great question

[@studywid]

Received electromagnetic rad, the most valuable raw information that their brains would process. Our eyes are the source of EM waves as they absorb energetic photons. My understanding: EM rad is carried via photons - which enter our eyes and activate receptors depending on the amount of energy the photon right, it hits our retina and deflect those photon at the same time. The deflected photons in our cornea is a fuel for other eyes. That's probably why animals has eye contact with us, to absorb those deflacted photons

[@briseboy]

1. Error of scale. 2. What canids have that you don't, is a tepetum lucidum, which reflects so that photoreceptors get more light from the ambient. They see in lower light. Thus, go back to high school biology and DROP the mental delusions you attempt to foist on us.

[@vickychrist5849]

I still find it incredible that I have access to this kind of knowledge! OK, I have a question is there any paper researching if our brain works linearly in regards of face recognition? For example, if I know a person, that I haven't seen let's say for a decade, is it more easy to recognize it from an recent photo or from a photo of its childhood? How does our brain cope with reconstructing a face through time?

[@Menaka_Sharma]

This is an interesting concept in the human brain. As we know , the human brain is highly fascinating and highly organised. When we see a person , or know a person , we organise them unconsciously into different categories. Like oh his face is an oval , he’s tall , he kind of looks like my 3rd grade teacher, etc. what you are asking is how we recognise a person we are seeing after a decade. Certain characteristics are prompt , and yes , the childhood photograph will be a much faster memory trigger , but the intelligence system analyses the parts of the persons face that are retained , though a little modified. Since most of the characterises (organised memories) have changed , it is difficult to recollect. The brain puts together bits and pieces of information it can still find and then you suddenly remember oh wait , this is my childhood friend

[@uab371]

Excellent question. Last sunday i saw my husband come up the hill and I was attracted to him. He looked great. But my husband was killed 5 years ago. In the 1/100 th of a second. he looked well, and he didnt have the limp he had when he was alive with me. He limped I guess from wearing his wood carpentry tool belt. I didnt notice it that much when he was alive with me. None the less . Maybe He came to say high five Love ,everything worked out in the wash I am finally doing well again. ready to rocket. who can say what I saw ? if anyone could pull a stunt like that to come see me and both know all is okay, it would be him. or I could be completely nutz. I am pleased to be in your company. I do welcome your input. Lettuce gather at the round table , picnic, bbq, decide easily a good path forward, we got thiis I love you all and welcome your input.. Hate me as much as you want, I can take it. Love, Melia Joy

There is any possibility that the FFA and the OFA some how are connected at the thalamus?? Since there are more axons going backwards from the visual area to the thalamus than viceversa?

Isnt experimental design right title?

[@sidecardude]

49:46 Nancy comments that she could not find the part of the mind that reacts to snakes, maybe that is because it is literally imprinted in our bodies so we react before we can even think about it. Jordan Peterson had mentioned this while discussing evolution, snakes, and the bible. Just a thought, remember him saying something about the reaction imprinted in our spinal cord.....

[@bradsillasen1972]

Even though it seems as if the innate aversion to snakes would naturally be selected for, there are, surprisingly to me, studies which refute this and suggest it is a learned behavior. Innate aversion may well be only a sort of "just so story". As a side note, remember, only about 7% of snakes are considered to be dangerously venomous. That might dilute any selective pressure to aversion.

[@sidecardude]

@@bradsillasen1972 they are never going to find anything in our brain if its imprinted in our spinal cord, no story, its there.

[@bradsillasen1972]

@@sidecardude If indeed we store or process information in our spinal cords, then I have missed something big in my cursory study of neural anatomy. My understanding was that the spinal cord is pretty much just a bundle of axons to conduct signals to and from the brain. Can anyone answer to that?

[@sidecardude]

@@bradsillasen1972 We react and move faster than the signals can propagate through our brains to our bodies. Looking for the clip on the spinal cord still..... kzbin.info/www/bejne/jaCXmoFtdqyVqc0&ab_channel=JordanBPetersonClips

[@bradsillasen1972]

@@sidecardude Thanks for that. I did watch and even offered a comment. I won't comment on Peterson directly here as that is apparently verboten. My last comment was deleted for that I suspect. And I'm ok with it and think I understand why. The video to me was almost unintelligible, and summarily uninformative, with a large measure of conjecture and heavy reliance on vague metaphors. I can't read poetry either ;-) Back to the point. I'm accepting that innate snake aversion/fear may well be so in at least some cases. But, the lack of inhibition by toddlers that I've experienced first hand, and anecdotally, confuses the issue for me. I know that I was never really afraid of snakes, but rather excited and curious.

i read recently that monkeys recognize each other by there butts as easily as their faces, probably because animals evolved from herd species where the animals followed each other in line face right against the butt of the next animal, would be interesting how this butt recognition brain areas maps on all your data, and just so u dont feel too superior to the monkey or herd animals, it seems humans still have quite a bit of butt focus especially in the less educated classes. based on music videos and such. do monkeys twirk do chimps. could be the title of the lecture when the data is collected.
