And I’m drawing these surrealist illusory illustrations perfectly sideways. I can’t do that by hand with a pencil unless I take my time and have something to draw. Never have I ever before the app, drawn creatively or/and sideways, speedily nonetheless.

It's crazy that there are people out there who used this lecture to get their degree and become a neurosurgeon or something. And I'm using this lecture to keep me focused to wash my dishes. Also, bless MIT for making this course free. When I was a kid, I loved learning so much I played school during summer break. If I had a math workbook from the previous year, I would finish it. The school gave us an old science textbook to keep so I studied from it. I watched documentaries and CSPAN for fun. If I had this course available to me back then, I would've been the happiest kid around. I hope somewhere out there, there's a kid who is like I was and can learn as much as they want.

At the start, the professor says only humans have precision throwing. As with many other things, we take it to a whole different level. But it occurs to me that many monkeys throw their feces accurately. Just saw a video of that on Reddit yesterday, coincidentally. The baboon got it right on the persons face from about 10 feet away, through a cage. Also various animals very accurately project their venom, or other fluids.

The ratio of the number of connections between the cortex, sensor and thalamus may indicate that the sensor is used for feedback filtering. Axons may 'feel' a field of holographic information then use the sensor to filter in specific features from the sea of waves. That scent is sent directly to the cortex is perhaps a hint to unlock how molecules, of the same type, are formed as unique keys to store and relay memory in the gaps between synapses.

@erikbelfrage4600

I had the same thought, but in layman terms - scent memories always seem to be the most profound, and here it is shown how it's linked directly and not via the Thalamus like all other senses... Do you mean that molecules could somehow be "stored" in connection to synapses?

@scenFor109

@@erikbelfrage4600 Yes. The molecules themselves needn't be stored but unique energy signatures of individual molecules may be linked to memory. An allegory would be of plant leafs. Each type of plant produces the same type of leaf but each one is structurally unique. Or grains of sand of the same mass, that produce a piezo electric charge under pressure, which also produce a unique energy signature because of structural differences in familial types.

Also I think it's interesting that the huma MT detects position and presence of position, but not direction, because that's roughly in tune with my understanding of the quantum mechanical description of the world where position and momentum are non commutative. It's like describing a group of vectors in a position space

That is nice to see MT has movement direction coding in the frontoparallel plane; but, surely there must be movement direction coding in terms of 3D Cartesian space somewhere too. Interesting you say it is very highly metabolically active, as I think it is fairly safe to say from phenomenology that attention to motion uses higher frequency 'frames' of consciousness (transient increase in 'sample rate' for the extra precision to understand motion [I'm not saying retina/VC is sampling at higher rate; rather I'm saying whatever the brain gathered it 'prints to consciousness' at the higher rate so that PFC/cerebellum can better fine tune behavior]).

There is an area on the retina that has no photosensitive cells. That is where the optic nerve joins the retina and takes the signals from the retina to the brain. The brain "paints" in the missing info in the picture so we don't "see" the gap in our perception. QN: How is this gap mapped on/handled by the retinotopic map? And where is the algorithm located that fills the image gap? In order to fill the gap, surely it has to analyse the overall image first in order to insert the correct missing part and avoid an incongruous result? Yet our consciousness is not aware of any time lag in our perception of the image? (Hope that all makes sense.)

Experts argue there are as many as 33 senses so is there 33 maps

What was the video switcher person thinking during the afterimage demo??? I love stuff like that, but in order for it to illustrate anything, you have to hold the screen in place during the demo and not switch around to the camera view. I mean seriously, I appreciate the free high quality education, but that's like messing with us!

Pituitary gland connected to hypothalamus ,between the optic nerves, is rather important for ‘everyday health’ binding the brain with the endocrine system. A most important nexus in researching peoples health problems both physical and psychological, the brain itself is hormonal, its important to understand that , hormones seriously affect psychology (very unexplored but expect big pharma to oppose you if you do)

If you google, it's difficult to actually find any good photos of, for example, the amygdala. So I started to think that what you really mean when you talk about these regions is that they are specific areas within the brain, that have been mapped out when measuring the activity of the brain. That these areas reside in larger physical shapes in the brain. But this is not correct, right? They have distinct shapes inside the brain, right?

20 Watts! Amazing!

love the lectures, don't like how you cut us out of the after effect demonstration.

Probably a stupid question, but is it possible to access the reading assignment scientific papers or must they be purchased? I presume MIT have a license for them but us mere mortals must pay up :-) ?...

So the thalamus is the sensor fusion system?

i wonder if there are degrees of viral encephalitis ??

I wanted to ask, why is it that the olfactory nerve does not make it's way to the thalamus and instead ends up in the olfactory cortex directly? Can someone confirm why does this exception exist? Is there any special property of the olfactory system that lets it override the route that other sensory nerves take?

Another commentor got me thinking about that. Perhaps it's because smell is a sense that interacts directly with the chemical/thing it's trying to identify? There's less to interpret. Not sure if taste has a connection to the thalamus or not, but seeing as how the two are linked......

@@dcpunk4 I mean, I can see how that may be true, as the tongue does have mixed nerve receptors with both tactile and gustatory functions so that can take the route to the thalamus but the olfactory nerve, as you said might interact directly with vapors and chemical scents like pheromones and even chemical substances can be distinguished on the basis of smell. It does help in distinguishing a lot of things that you couldn't possibly solve with touch/sight/hearing/taste.

From my classes on this topic a long time ago a teacher told us that it was probably an evolutive advantage in the recognition of predators and environment, since with your eyes you're limited to whatever is in front of you. Also that way your olfactory senses work even if you're sleeping

I mean this may sound stupid, but I finally understand grey vs. white matter. Makes complete sense.
