If we are talking facts, neurons don't use electricity, it's a cascade of released ion potentials. Thats why nerves are so much slower than electrical signals.

But poltergeist cat is real!

Fun fact, the average adult brain also has a credit cards worth of plastic inside. So that bacon has some company!

Once I put my head up to the EFTPOS machine and the payment actually went through

Additionally, the average brain is about 1300 grams. 0.5% of 1300 is 6.5 grams, and plastic credit cards weigh roughly 5 grams.

0.5% is really hard for me to visualize. A credit card in everyone's brain is unfortunately easy.....

Contrary to popular belief, we're all profoundly stupid. Even the smartest among us spend enormous effort in their struggle to comprehend our surroundings.

[–] [email protected] 19 points 15 hours ago (3 children)

At least half of us are below average.

[–] [email protected] 1 points 33 minutes ago

If we're talking about IQ, than no. An IQ between 85 and 115 is considered average. This entails 68% of the population. So, only 32% of people are not average and only 16% are below average.

You mean the median? :3

It's not. I assure you there are far more outliers on the low end.

[–] [email protected] 1 points 19 minutes ago

But I'm sure there are more people with 200+ IQ than with <0.

[–] [email protected] 3 points 3 hours ago

I endeavour to be as stupid as possible so more people can be above average.

Maybe the brain will one day invent something more tiresome than watching reddit users exchange tautologies.

[–] [email protected] 16 points 17 hours ago

I'm doing my part!

Prions are just like seasoning right?

I often describe myself as "3lbs of mostly fat piloting a meat mech." To the point that my wife sometimes refers to injuries as malfunctions/damage to her meat mech.

[–] [email protected] 1 points 28 minutes ago

I’m an ugly bag of mostly water.

Fitting, really, to be a dream to meat.

You momma is FAT (with water and salt)

[–] [email protected] 9 points 15 hours ago (1 children)
[–] [email protected] 7 points 13 hours ago (1 children)

Yeah your momma’s so big she’s not even FAT she’s exFAT and can store files up to 120 petabytes

[–] [email protected] 5 points 11 hours ago

Yo mama's like exFAT; she's got no permissions so anyone can access anything and her low requirements mean she gets embedded everywhere.

OP has a baby in their head

Brain uses more wattage than a lightbulb, unless we are counting incandescent bulbs because it makes the stat seem more impressive.

[–] [email protected] 33 points 15 hours ago (2 children)

That phrase first came out when incandescent bulbs were the most common, so they consumed like 60W vs 7W for an equivalent LED bulb. The brain is somewhere around 20W.

I don't give a damn about Lemmy points, but you just said essentially the same thing as the above commenter and the Lemmy points are diametrically opposed. I love it!

[–] [email protected] 5 points 15 hours ago (1 children)

It was estimated back when incandescent was standard.

Keep in mind that’s not accounting for energy consumed from neurons burning oxygen, which accounts for 20% of a human body’s consumption.

20% of your bodies energy is about 20 Watts.

Normal-weight humans burn about 2200 kilocalories a day, which is about 9.2 megajoules. There are 8640 seconds in a day, so that works out to roughly 100 joules per second, or 100 Watt. 20% of that is 20 Watts for the brain.

[–] [email protected] 1 points 56 minutes ago

That's rest consumtion tho.

[–] [email protected] 2 points 13 hours ago

Well done. So even added to the electrical consumption it’s less than an incandescent bulb. Incredible.
