The T. Rex had as many neurons as these surprisingly smart African animals

The T. In addition, Rex were as intelligent as the baboons. Furthermore, It is at least the conclusion of a study which. Consequently, after having compared the brain of the T-Rex to that of modern birds like the emeus and the ostriches, has calculated mathematically how many neurons could be housed in the brain of theropods. Nevertheless, The details of this work are published in The Journal Of Comparative Neurology.

Composition neuronale – T. rex had many neurons

Understanding the neuronal composition of the brain of dinosaurs would make it possible to have a much better overview of their behavioral and cognitive capacities. However, Unfortunately, the brain soft fabric rarely fossilizes. Additionally, However. when the bone brain fabric is preserved, the volume and therefore the mass of the brain can be estimated by computed tomography. If the relationship of scale between brain mass. the t. rex had many neurons number of neurons for the clade is also known, this relationship can then be applied to estimate the neuronal composition of an ancient brain.

This implies Suppose proportionality. In other words. for the subject that interests us today, you must have good reasons to believe that the same proportionality that applies to birds (descendants of theropods) also applied to dinosaurs like the T-Rex.

For the neuroscientist Suzana Herculano-Houzel, the key to making hypotheses sensible on proportionality is based on the consideration of dinosaurs as separate groups. There was a time when disparate groups – such as Sauropods and Theropods – were all grouped together. Over time. discoveries, it is ultimately more and more clear that few rules could be applied to dinosaurs as a whole.

By examining the theropods, however, it became clear for the researcher that these animals had brains sizes similar to those t. rex had many neurons that could be expected to find in a bird of the same magnitude. As such. it then becomes reasonable to expect the same scaling rules to apply to the T-Rex as to the descendants of theropods, such as modern emeus and ostriches.

As many neurons as modern primates

Using a database published on the number of neurons in the Telencephalon of existing Sauropsides (birds, squamates and Testudines), and using mathematics, neuroscientist has therefore been able to estimate the number of neurons of several famous theropods, t. rex had many neurons such as Tyrannosaurus Rex.

The latter, according to the results, had respectively a number of telencephalic neurons similar to that of baboon. If this were to be confirmed. then these dinosaurs were not only enormous, but also with a flexible and potentially lifespan cognition (there is a relationship between the number of neurons and the lifespan)-perhaps up to 40 years.

Living so much time with so many neurons could therefore have given these animals the time and the capacity for reflection necessary to resolve problemsor Use tools.
