Neural representations of visual memory in inferotemporal cortex reveal a generalizable framework for translating between spikes and field potentials Translating neurophysiological findings requires understanding the relationship between common measures of brain activity in animals (spiking activity) and humans (local field potentials, LFP). Prior ...

🚨 New preprint!

Why do some insights from spikes translate to field potentials while others don't? In this paper we compare visual memory representations in spikes and LFPs to propose a general framework that answers this question.

A dynamic spatiotemporal normalization model captures perceptual and neural effects of spatial and temporal context The effects of spatial and temporal context on sensory systems have mostly been studied independently of each other. This study shows that the modulation of visual perception and neural activity by th...

Happy to share this new paper from the lab led by Angus Chapman, now out in PLoS Biology! It presents an integrated spatiotemporal normalization model for continuous vision. @afchapman.bsky.social

BOLD signal changes can oppose oxygen metabolism across the human cortex, Nature Neuroscience

BOLD signal changes can oppose oxygen metabolism across the human cortex, Nature Neuroscience

fMRI signals β€œup,” but neural metabolism might be going β€œdown.”

In our @natneuro.nature.com paper, we demonstrate that about 40% of voxels with robust BOLD responses exhibit opposite oxygen metabolism, revealing two distinct hemodynamic modes.

In this preprint, we concurrently fit the HRF alongside pRF parameters doi.org/10.1101/2025...

- HRF varies between visual areas
- HRF also varies with pRF stimulus designs (due to nonlinearities?)
- Esp. when fitting complex models this can skew results a lot!

Diving in with Nachum Ulanovsky With an eye toward realism, the neuroscientist, who has a new study about bats out today, creates microcosms of the natural world to understand animal behavior.

Naturalistic approaches such as Ulanovsky’s open up β€œpotential opportunities to really reveal why the brain is structured in the way it’s structured,” says Iain Couzin.
