The Circuits in our Brain -- The new way to study brain signals

[sergiobanguer2]

can you put some bibliographical references with peer-review journals?

[crlegendy]

@sergiobanguer2 The bibliography is in my book -- this little video is only meant to offer a glimpse at the methods

[Theodorus5]

Dear Charles, a most excellent exposition! Thank you. Are you planning on doing more videos on different chapters from your book?

[crlegendy]

@Theodorus5 Thank you for your kind comment. Yes, I hope to put up 1-2 more videos as soon as I get a chance. Right now I am too preoccupied with writing my theory of the astroglia cells, which is moving forward much too slowly. (I think "the miracle of the brain" is to be sought in the glia cells -- the neurons only provide the communication network!)

Nice video. Your figure at 7:42 posits that the firing of conjugate pairs can act within a call assembly to form a perceptual whole. Yet the latencies indicated along the serial processing within the network make me wonder how this could be encoded within a moving visual scene. The binding of all these trains of coherent spikes into a perception of an object still seems obtuse to me.

@ilovemingers  I address the problem of moving images in great detail in my book, under the heading of "tracking." The conclusion to which I come is that as long as pursuit eye movements can sufficiently reduce the drift of the retinal image, the model will continue working.

Your work is incredible. I am doing similar work, but with a language framework.

the grandson of einstein .:)) . thank god . u came

I would like to ask for the help of any anatomy specialists doctors and teachers to provide a dentist in the making(me) to better understand the human body for my medical university examination. I am now in high school and am required to learn 2 years worth of anatomy teaching especially the nervous system and analyzers. Any videos and documents referring to these are welcomed.

INTERESTING!

[crlegendy]

I agree that the "points and directions" representation of shapes I describe has similarities to certain computer graphics concepts -- and I in fact do use the term "polygon graphics" in my book! I also agree that in the recent years in vivo microscopy techniques have made such impressive advances that it may actually be feasible to test, experimentally, some of the things I say..

More complex forms and surfaces are displayed as continuous sheet of triangles connected in their ribs.

It is whether you proved that our brain processes visual information as a computer and thus already is one, or you discovered a way to communicate between a brain and computer.

You think it is possible to connect the brain through some scanning like FMRI or just electrodes directly to a computer and control what is displayed by 3D software just by concentrating on certain shape?

[Yagdash]

If it is possible to scan the human brain to the level of resolution of single brain-cell and record when it fires a signal it is very easy to reconstruct the exact geometrical form in 3D graphical program. If this data correctly deciphered and cleared of noises, leaving only the signals from cells that represent vertices of a form.

[Yagdash]

This is exactly how visual information is processed by 3D visualisation software algorithms, in OpenGL library for example.

Every 3D shape is described as combination of "primitives", lines and primitive forms ccomposed of lines, each line expressed as a vector between two sets of coordinates. Each set of coordinates [X, Y, Z] represents a single point in space.

Very interesting video. I look forward to reading your book. Davidlewis

Thank you for such a nice presentation. But this idea goes against the finding of cells responding to moderately complex visual features individually ! am bit confused in this regard

[crlegendy]

@jeremealmore -- The cells responding to complex features, as reported by Gross, Logothetis, and others, are all found in the higher-level visual areas, typically the inferior temporal cortex. What I am addressing here (and in my book) is a question regarding lower-level processing: How does the shape information manage to get past the primary visual cortex? Incidentally, I consider it likely that the inferotemporal cells in question are also members of larger cooperative groups.

[gradschoolerasmusmc]

Interesting theory. Shows the beauty and complexity of our brain.

[tvaddict69]

Thanks so much! I am currently a neuroscience undergrad very much interested in the field of neural networks and I think your work is fascinating! I look forward to reading your book.

[crlegendy]

@tvaddict69 Delighted to hear you liked my video -- I hope you will enjoy my book!

[msbergwanderer]

This is awsome! Wow, a totally new way to look at the brain - I mean they way neurons interact, where they get their information from etc. I am sure this new theory will get noticed by the professionals. I am certainly going to buy the book, this is just so exciting!!! What a clear and interesting presentation!
