AI synopsis
What people are saying
The discussions frequently reference the comparison of avian brains to those of primates, with participants noting phrases such as 'Why Crows Are as Smart as 7 Year Old Humans', emphasizing the remarkable intelligence of crows and similar birds. The tone is generally positive and enlightening, with terms like 'amazing' and 'fascinating' used to convey admiration for the cognitive capabilities of birds, thus reinforcing the overall sentiment regarding the impact of this research.
The majority of discussions overwhelmingly support the findings of the publication, highlighting shared enthusiasm about the cognitive abilities of birds.
Contributors express strong curiosity and take great interest in the research, as evidenced by multiple references to various aspects of avian intelligence.
Many discussions dive into the intricacies of neuron density and its implications for cognitive function, indicating a high level of engagement.
Contributors perceive the findings as significant, recognizing the implications for understanding animal intelligence and cerebral capacity.
Abstract in brief
- Birds have a surprisingly high number of neurons in their forebrains, similar to primates, despite having smaller overall brain sizes.
- Research shows that parrots and songbirds have about twice as many neurons as similarly sized primate brains, indicating they pack neurons more densely.
- The concentration of neurons in specific areas, particularly the pallial telencephalon, plays a significant role in supporting avian cognitive capabilities.

@ranoeldelbar Básicamente la densidad neuronal (la cantidad de neuronas por un volumen dado) es muy superior en esas aves que en el cerebro de mamíferos (incluyéndonos), y la proporción de neuronas dedicadas a cognición también es mayor que en el nuestro (paper, 2016) https://t.co/UEzrq5Xle9
@TheDavidSJ @norabelrose From https://t.co/RmKEZNtsN1 looks like corvids are already kinda scaled songbirds. The neural density is just twice that of mammals, which gives not that much difference in the signal propagation, but the neurons are distributed differently among the parts of the brain.

Avian neurons consume three times less glucose than mammals (https://t.co/gB1O80E1sG) and are considerably more efficient per unit of brain mass (https://t.co/dqSXKlqbTO). So the next time you get called 'bird brain', take it as a compliment!

@obonicus @ylecun @ESYudkowsky As for the crow, bird neurons are smaller than mammals & thanks to this, they are more energy & mass efficient. Their high level of intelligence that is comparable to say, a whale or dolphin is because their brains have higher complexity. https://t.co/gpxUXcfWco
@blacksmoke1033 https://t.co/VKxy5TcKf5 Not as limited as you thought. “High neuronal density in the telencephalon appears characteristic of all birds. This means that neuronal densities in the primate pallium are matched by those of chicken and emu, but surpassed by those of parrots.”
