Hence, the octopus’ brain is the subject of study from animal neuroscientists — and one of the main ways we’ve learned about octopus brains is through lesioning studies.This is when ...

In addition to a central brain located between its eyes, an octopus has eight separate clusters of nerve cells, called ganglia, at the base of each of their eight arms. Compared with most ...

Blending in with your surroundings is a crucial (and fascinating) skill in the animal kingdom, which is why many animals can ...

“If I chop off an octopus’s arm, it acts like sort of an independent entity for a while.” Overall, this spread-out network of neurons and autonomous parts makes the octopus brain “less of a control ...

The octopus couldn’t rely on chemical cues processed by its brain to find the food, as it typically does in the ocean, forcing the arm’s individual “brain,” or neuron bundle, to find the ...

Imaging the brain activity of an octopus was no easy task, either, Gutnick noted. An octopus on the sea floor. Image source: Andrea Izzotti/Adobe.

The octopus brain keeps growing and adding new neurons over the animal's lifespan. These immature neurons, not yet integrated into brain circuits, were a sign of the brain in the process of expanding.

“The brain’s real genius might lay in the cells we have neglected for a century,” Kozachkov says. Our heads’ octopus looks to have been dragging the strings all along. Sources: ...

Prof. Hochner (Hebrew University) and Prof. Lichtman (Harvard) reveal Octopus vulgaris' neural intricacies for learning via advanced mapping. Unique interneuron types in a feedforward structure ...

The California two-spot octopus can edit the RNA in its brain to produce different proteins as ocean temperatures fluctuate, a new study finds. Accessibility links. Skip to main content; ...

(There’s a rather gruesome demonstration of the latter fact: “Amputated octopus arms,” Olson says, “will still move around on their own without commands from the brain.”) ...
