This work was inspired by @tomerullman.bsky.social's “illusion illusion” paradigm (arxiv.org/abs/2412.18613) where VLMs mistake illusion-like images for genuine optical illusions. In both cases, models respond to what a problem looks like rather than what it actually requires.🔮

Neurons active while seeing food were reactivated during sleep. Taken together, our results reveal that reliable neural signatures in high-level sensory and motor regions form the neural substrates for natural behaviors. 8/8

SP Arun @sparuniisc.bsky.social · 29/04/2026
Key events during these interactions elicited distinct and reliable neural signatures that reflected the encoding priorities of each region. Visual and motor regions were clearly dissociated in screen tasks, but were dissociated only at specific events in the natural task. 7/8

SP Arun @sparuniisc.bsky.social · 29/04/2026
Here, we provide evidence for the latter possibility through wireless recordings in freely moving monkeys performing natural tasks as well as controlled screen tasks. During natural interactions with food, neural activity was decodable with striking fidelity 6/8

SP Arun @sparuniisc.bsky.social · 29/04/2026
Alternatively, natural behaviors might elicit reliable neural signatures in high-level visual and motor regions which contain invariant representations, and involve correlated sensory and motor information that leads to apparent mixing. 5/8

SP Arun @sparuniisc.bsky.social · 29/04/2026
The prevailing view is that natural behaviors are more noisy compared to controlled tasks, and involve mixing of sensorimotor information. 4/8

SP Arun @sparuniisc.bsky.social · 29/04/2026
Abstract Natural behaviors are challenging to study because they involve large variations in sensory inputs and motor outputs across trials. Even the simple act of eating can involve seeing food from many angles and reaching for it differently each time. 3/8

In both monkeys, while grooming, neural activity was predicted better by the partner’s joints and his brain activity. Thus, the receiver of grooming drove the social interaction, not the groomer. Our findings elucidate the neural basis of primate social interactions in an ecologically valid setting.

SP Arun @sparuniisc.bsky.social · 22/04/2026
Key finding: Neural activity encoded key social variables such as allogrooming state, partner identity and joint movements. Surprisingly, neurons in the high-level visual cortex continuously tracked a social favor signal, i.e. net duration of allogrooming given versus received.

Is mental imagery a single process? Our meta-analysis of 46 fMRI studies suggests not. We find a key divide between object imagery (visualizing an object in rich detail) and spatial imagery (mentally transforming objects). This split mirrors the ventral and dorsal streams of vision
