we have a backlog of work coming out over the next year on the development of innate approach/avoidance behavior. Here is part one of five. I hope this helps folks looking at the roots of visually -guided approach v. avoidance decision making.

New in Neuron 👁️🧠🧪: Can AI help a cortical visual prosthesis control what the brain actually does after electrical stimulation? We used a bidirectional implant to model and shape stimulation-evoked activity in human visual cortex. doi.org/10.1016/j.ne... #UCSB #AI #BionicVision #Neurotechnology
Schematic comparing three methods for producing a target neural response with a cortical electrode array: direct 1-to-1 mapping, a learned inverse model, and gradient-based optimization. Each method generates a stimulation pattern that is passed through either a simulated forward model or tested in vivo. Resulting neural responses are shown as electrode-array heatmaps, illustrating how closely each approach reproduces the target pattern.

Very happy to share our new review on visual computation in the cephalopod brain, with @vangeliqueallen.bsky.social, out now! We discuss exciting recent advances in understanding how the radically different brain of cephalopods processes the visual scene. 🐙🔬👀 www.sciencedirect.com/science/arti...

Call it #ExplainableAI or just making sense of complexity. We establish a direct link between DNNs fit to #AuditoryCortex and more intuitive subspace models from the 2000s.

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

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) www.nature.com/articles/s44...

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 www.sciencedirect.com/science/arti...

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. www.biorxiv.org/content/10.1...
