The octopus brain has teased researchers since the 1960s, but recording from it seemed impossible. Cris Niell and his team’s calcium imaging experiments finally “showed that this brain could be studied,” says Sam Reiter.

Cephalopods, vision’s next frontier
For decades, scientists have been teased by the strange but inaccessible cephalopod visual system. Now, thanks to a technological breakthrough from a lab in Oregon, data are finally coming straight…

Can your AI beat a mouse?
Mice still outperform our best computing machines in some ways. One way is robust visual processing.
10 years ago I decided to work on HARD behavior driven by COMPLEX visual processing. And that risk is paying off now. #neuroAI 1/n

Applications are open for the first Cephalopod Neuroscience Gordon Conference, to be held February 2026! Hope to see many of you there! 🐙🧠🔬

Our first paper on altered states of consciousness induced by #breathwork is officially out now! It addresses four big questions: (1) Can simple breathing alter your consciousness? Most definitely! And in very similar ways to psychedelics! (1/4)

Decreased CO2 saturation during circular breathwork supports emergence of altered states of consciousness - Communications Psychology
Circular breathwork induces altered states of consciousness similar to psychedelics, predicted by decreases in CO2 saturation. Acute physiological and psychological dynamics during breathwork in turn ...

Recent studies found pronounced neuromodulation in the early visual cortex due to locomotion and spontaneous body movements in mice but not in non-human primates. We reconciled this dichotomy in this new open-access feature review @cp-trendsneuro.bsky.social

Is the impact of spontaneous movements on early visual cortex species specific?
Recent studies in non-human primates do not find pronounced signals related to the animal’s own body movements in the responses of neurons in the visu…

When we enter a new environment, we use visual input to rapidly build an internal model of the local spatial environment. How does our brain do this? We review past literature and suggest some new ways forward in our new review in @currentbiology.bsky.social: authors.elsevier.com/sd/article/S...

Sniffing helps animals identify smells and connect them to places and events, but noses can’t sense time or place.
How do brains connect odors with internal models of the world?
Our preprint suggests that the olfactory bulb participates in this connection.

More cephalopod content for your holiday reading! (don't be fooled by the title - there's some funky cuttlefish facts in there too)
