In conclusion - this is so cool and I think we are only beginning to unravel the secrets of the brain!

It seems not all neurons (even those from homologous brain regions) are created equally between species. More specifically, human dendrites appear to have unique computational abilities arising from calcium-mediated action potentials (see paper for details).

This is fascinating. I've long been interested in the following question: What makes human brains unique? Obviously, the sheer # of cortical neurons (~16 billion) compared to other species is important - but there might be more to the story...

No, that's Lothlórien. Mandalorians are a microscopic lifeform that resides in all living cells - without them, we would have no knowledge of The Force.https://twitter.com/SlagOffTwits/status/1195768385704996864 …

Please check out the paper (from the lab of Dr. Suzana Herculano-Houzel, who pioneered some of the neuron-counting methods that make this possible) about the elephant brain here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4053853/ … And please correct me if I got anything wrong!

To wrap things up, I hope this demonstrates how different species have different brain organizations that serve their respective specializations. The raw neuron counts are themselves interesting, but breaking down the numbers is where it really gets fun.

Given that so many elephant neurons are allocated to the cerebellum, how many are left to comprise the cortex, which is more associated with cognition? The study counted only 5.6 billion cortical elephant neurons, around 1/3 of the 16 billion found in humans.

Although it has not be confirmed, the authors of the paper speculate that the elephant trunk, being an extremely dexterous and sensitive appendage with countless degrees of freedom, explains the need for huge numbers of neurons dedicated to motor control.

For context, the cerebellum, which is that strange looking portion of the brain that is nestled beneath the cerebrum, is thought to primarily be involved with motor coordination and not cognition. So, why does the elephant have all those cerebellar neurons?

For example, the original paper (linked to at the end of the thread) where the elephant numbers come from states that an incredible 97.5% of elephant neurons reside in the cerebellum! (Note: 80% of human neurons are in cerebellum.)

Thank you
@EvanSandhoefner for illustrating this fascinating concept, but I just wanted to address the elephant in the room. That there are 257 billion neurons in the elephant brain is impressive, but it's important to consider that not all neurons are equal.https://twitter.com/EvanSandhoefner/status/1187880252950794240 …Prikaži ovu nitHvala.

Hey
@TrustlessState, I loved the most recent episode of@POVCryptoPod involving MakerDAO vs. Bitcoin. Was also refreshing to hear a constructive conversation from people with different crypto-perspectives. Keep up the good work.Hvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte.
