Scientists Create the World's Largest Brain Map

Scientists have created the first precise 3D map of a mouse brain showing over 500 million synapses and 200,000 cells all within a 1 mm cube of brain. The scientists behind this feat hope it will eventually shed light on how human brains store visual memories.

What are we going to do tonight, Brain?
Same thing we do every night, Pinky.

[jaha]

-What have you done?
-I've mapped a mouse.
-How did you do that?
-I've used the mouse.

[ars-brms]

it's insane that stitching together all of those images took longer than that mouse lived for, brain is the craziest organ by far

You forget why you're there after wandering into the kitchen because your Working Memory has dumped its buffer of old items to add new items. This typically happens when you aren't staying focussed on your task, so the brain will judge that any memories related to your previous task has a lower priority to new information: such as whatever you just looked at when entering the kitchen & the cascade of memories that seeing it has pulled out of your medium/long-term memory.

It’s wild how even the smallest of critters has an entire universe inside their brain that ultimately decides if they step in a mousetrap or not.

[Shlooomth]

Holy crap that’s how dense neurons and their connections are.

Just a heads-up: That coffee we gave you earlier had fluorescent calcium in it so we can track the neuronal activity in your brain. There's a slight chance the calcium could harden and vitrify your frontal lobe. Anyway, don't stress yourself thinking about it. I'm serious. Visualizing the scenario while under stress actually triggers the reaction. -- cave johnson 1957

What I love about science is that we’ll always be on the beginning of new, exciting things because when we figure out one thing we discover a new question to be answered

Brings a whole new meaning to “ clicking together” in your head

Currently we are trying to find out how can we compress this data without losing information before mapping the whole brain. It has an enormous size but every small detail is important. We discussed this with Allan institute previous year, it is cool seeing the project here.

0.2% of the mouse brain took 5 years to map. And their next goal is to map... let's see, here... oh yes, 99.8%...

[bligabliga]

opens fridge*

"why did i come in here again?"

begins years of brain research*

[sjonesie]

I love how enthralled the mouse was with Tom & Jerry.

[ellisxy]

This is actually the coolest thing ever to me.

I have this feeling that our brains have another level of neurological communication outside chemical, electrical or physical interactions. This feeling is born from the knowledge that a subject can slip on a cap wired with sensors which detect signals from the brain as it operates. What’s to say that neurons are not able to pick up signals much like the sensor cap? Can a neuron detect a signal like the sensor cap from a neuron on the other side of the brain? Let’s call that a bit. How many links can be made from one neuron to all the others in this way? If they all do this the computational complexity would be off the charts. However as highly unlikely as this may be I still feel like there might be something to this idea…

[thelizard]

Can you please give us all the link to the published version of this experiment as well

[criscat]

Fun fact: the reason we forget things when we walk into a new room is cause its a survival mechanism, that helps us stay focused and take in the new environment to watch out for predators or any dangers.

[konrad]

I think the cause of "forgetting why you've entered the kitchen" is change of environment and potential activities. I often have the same temporary dementia thing when grabbing my phone with a specific task in mind

[ferociousfeind]

I like that neuroscience is a bottom-up approach, and psychology is a top-down approach. Psychology examines agent (mostly human) behavior as a series of causes and effects, establishing connections by testing real world brains all at once in reality. Neuroscience starts at the bottom, from first principles, and attempts to map out every little detail of the brain, using a totally different set of causes and a totally different set of effects. They're approaching the same fuzzy middle ground, from opposite sides of the issue. They have totally different principles, and yet they're both describing true phenomena that are closely linked.

This is one of those rare, awesome shorts. Well done.
