Really delighted to share our new article in Current Biology showing that the cingulate-to-dorsolateral prefrontal pathway is not involved in trial-to-trial short-term adaptation but rather in sustained motivational control.

A sad day for Neuroscience in the Netherlands.
Dutch lawmakers have approved the phase-out of primate research at one of Europe’s biggest facilities. Neuroscientists are worried.

Nonhuman primate research to lose federal funding at major European facility
The Dutch Senate has ordered the Biomedical Primate Research Centre in the Netherlands to shift its funding away from primate experiments by 2030.

Our newest preprint! Work led by Ben Dykstra (co-mentored by @gordonberman.bsky.social). Some of the first recordings from the iCA3 region during social behaviors. Ben found that iCA3 neurons more strongly represent social recognition information relative to iCA1 . www.biorxiv.org/cgi/content/...

(1/8) My latest study is out in @nature.com ! Kudos to coauthors especially @jess-cardin.bsky.social and to @kavliatyale.bsky.social and @wutsaiyale.bsky.social for support. We find that gamma power in mouse visual cortex is caused by brief events of visual processing www.nature.com/articles/s41...
Flexible perceptual encoding by discrete gamma events - Nature
Using a new analytical method for tracking gamma band events in mouse visual cortex, flexible encoding of visual information according to behavioural context is shown.

Precision Neuroscience published their high-density ECoG in Nature Biomed. Eng.
The startup shows a 1,024-channel grid implanted through a cortical slit in pigs, and intraoperative neural recordings and stimulation in five humans at sub-mm resolution.

Minimally invasive implantation of scalable high-density cortical microelectrode arrays for multimodal neural decoding and stimulation - Nature Biomedical Engineering
A 1,024-channel microelectrode array is delivered to the brain cortex via a minimally invasive incision in the skull and dura, and allows recording, stimulation and neural decoding across large portions of the brain in porcine models and human neurosurgical patients.

New work! Learning is assumed to involve synaptic plasticity, but which specific synapses change to enable higher order cognitive functions? We actually find that cognitive flexibility involves potentiation of long-range GABAergic synapses from prefrontal PV neurons: www.biorxiv.org/content/10.1...
Synaptic plasticity of prefrontal long-range inhibition regulates cognitive flexibility
While glutamatergic synaptic plasticity is believed to be a fundamental mechanism mediating learning, the behavioral significance of plasticity at cortical GABAergic synapses remains less well underst...

Our new paper with @chrismlangdon is just out in @natureneuro.bsky.social! We show that high-dimensional RNNs use low-dimensional circuit mechanisms for cognitive tasks and identify a latent inhibitory mechanism for context-dependent decisions in PFC data.
