New paper in PNAS: Inversion of pop-out for a distracting feature dimension in monkey visual cortex.

Goal-directed behaviors like visual search involve both the selection of behaviorally relevant targets and the suppression of task-irrelevant distractors. This is especially important if distractors are salient and capture attention. Here we demonstrate a “pop-in” mechanism by which the visual cortex inverts a pop-out attentional capture signal into suppression to suppress distractors and facilitate visual search.

New paper in Current Research in Neurobiology: A framework and resource for global collaboration in non-human primate neuroscience.

International collaborations in non-human primate (NHP) research are accompanied by challenges bound to regulations. We surveyed the ethical and regulatory guidelines for 13 countries with NHP neuroscience research and compiled the data as a resource. Find the paper here.

Open Data Award of the Netherlands Instute for Neuroscience

Chris is the inaugural recipient of the Open Data Award of the Netherlands Institute for Neuroscience. The jury recognized our dedication to open science in general (see also Resources) and with respect to our recent pRF paper in eLife in particular.

Preprint: Pop-in: the inversion of pop-out for a feature dimension during visual search in area V4 of the monkey cortex

We have a new preprint out in which we describe 'pop-in', a mechanism that rapidly inverts pop-out for the suppression of salient distractors during visual search. The preprint is now available on bioRxiv and a twitter thread summarizing the work can be found here.

News: Exciting research project starting at the Vision Institute in Paris

A collaboration has started at the Vision Institute in Paris where we will be working on next-generation brain interfaces to study and restore vision..

News: Partial return to Utrecht University for a teaching position

Starting in 2022, I will be dividing my time between the NIN (research) and the Department of Experimental Psychology of Utrecht University (lecturing). I look forward to being back 11 years after getting my PhD..

Highlighted in eLife: Magnetic Resonance: Mapping the visual world to the human brain.

Our recent eLife paper diving deep into the neuronal basis of the visual population receptive field with fMRI and large-scale ephys recordings in non-human primates was higlighted in an eLife Insight article by Betina Ip and Holly Bridge titled Magnetic Resonance: Mapping the visual world to the human brain.

New paper in Neuron: Toward next-generation primate neuroscience: A collaboration-based strategic plan for integrative neuroimaging.

Open science initiatives are creating opportunities to increase research coordination and impact in nonhuman primate (NHP) imaging. The PRIMatE Data and Resource Exchange community recently developed a collaboration-based strategic plan to advance NHP imaging as an integrative approach for multiscale neuroscience. Find the paper here.

New paper in eLife: Population receptive fields in non-human primates from whole-brain fMRI and large-scale neurophysiology in visual cortex.

Accepted for publication in eLife! We estimated visual population receptive fields (pRFs) with several pRF-models using both fMRI and large-scale electrophysiology (>1k electrodes) in non-human primates. The results provide insight into the retinotopic organisation of the primate brain and the neuronal basis of the BOLD-based pRF approach commonly used in humans.

New paper in Neuroimage: Combining Brain Perturbation and Neuroimaging in Non-human Primates.

Our paper on the state-of-the-art in combining brain perturbation techniques with neuroimaging in non-human primates is now available at Neuroimage. The preprint is also still available at OSF.

Preprint: Brainhack: developing a culture of open, inclusive, community-driven neuroscience.

The inspiring Brainhack community has worked together to describe how Brainhacks benefit science and scientists. I'm happy to have been a very small part of this. The preprint is now available on PsyArXiv. [Update] Now accepted for publication at Neuron.

New papers: Sharing resources and results for and from NHP neuroimaging

Two papers recently came out in NeuroImage:
1) A collaborative resource platform for non-human primate neuroimaging
2) Sharing voxelwise neuroimaging results from rhesus monkeys and other species with Neurovault

Preprint: Combined Brain Perturbation and Neuroimaging in Non-human Primates.

Together with a large group of NHP neuroscientist, we wrote a paper about the state-of-the-art in combining brain perturbation techniques with neuroimaging in non-human primates. Huge team effort! The preprint is now available on OSF Preprints.

Preprint: A collaborative resource platform for non-human primate neuroimaging

We wrote a paper on the PRIME-RE platform and the kind of resources it houses. The preprint is now available on bioRxiv. The PRIME-RE platform itself is always open for contributions.

Check-out PRIME-RE

With a few other members PRIME-DE consortium I maintain PRIME-RE,a website that aims to be a resource hub for NHP neuroimaging. Check it out, contribute your own tools, and let us know if you have ideas for improvements! The future is collaborative!

New paper out in Neuron

Another piece by our PRIME-DE consortium came out in Neuron: Accelerating the Evolution of Nonhuman Primate Neuroimaging. It is the result of a meeting held at the Wellcome Trust in London last September and presents a collaborative vision for how to move the field of NHP neuroimaging forward. The future is collaborative! Get the (open access) paper here!.

New tool released: RheMAP

We recently created a tool to easily register non-human primate neuroimaging data from one standard space to another. We called it RheMAP and made both the data and underlying code freely available on Zenodo and GitHub. Check it out if you think this might be useful! Here's a Twitter thread about it.
