Faces elicit a particular pattern of eye movements from humans and monkeys. Here, we examine the role of face-selective cortex in this remarkable behavior.

I’m so thankful I had the opportunity to work with this team! @RezaAzadi_@AfrazArash and others
Fantastic paper by @HistedLab using calcium imaging and optogenetics. The results emphasize the pivotal role of recurrent connectivity in the visual cortex for processing sensory information. This, once again, challenges conventional feedforward models of the visual system.
🧠🚨: Our latest paper is out today in @NeuroCellPress! Led by @JonORawe, we show salt-and-pepper excitation& suppression in mouse V1 arises from purely exc opto input.
That means the excit-excit recurrent connections in cortex change how neurons respond to input. 1/3
We have another open postdoc position! Come join a collaborative community at the Laboratory of Sensorimotor Research, NIH. I welcome informal inquiries.
My lab @UDelaware is recruiting graduate students in cognitive neuroscience. Contact me if you are interested and please share the word. Here is more info about the MVP Lab: https://t.co/i7s7DIvuUh

Excited to share our new work “The whole is in the parts: non-holistic object parts predominate face-cell responses to illusory faces” with @kaspervinken and Marge Livingstone! https://t.co/zh1SiGaUqW
An amazing study sheds light on why faces are particularly salient stimuli for primates: SC neurons have a stronger response to faces compared to other objects, which is notably faster than what we had anticipated for feedbacks from visual cortex.Great job! @gongchen_yu@Leorkatz
New preprint!
We identified a mechanism for face processing that's centered on primate SC.
It's freaky fast (faster than cortical face patches), depends on inputs from visual cortex (as opposed to retina), and explains some puzzles in the literature. #tweeprint below. 1/n
5/5: This research opens up exciting avenues for further exploration and deepens our understanding of the intricate relationship between neural encoding of faces and our gaze behavior.
4/5: Our study provides compelling causal evidence for the role of face-selective neurons in guiding eye movements during face perception. It adds a crucial piece to the puzzle of how our oculomotor system uses high level visual information.
Here we examine the recognisable emotional information in a large set of “wild” facial behaviours.
Very proud of Houqiu Long and @nataliepeluso for leading this project. And thankful for the opportunity to work with @ShrutiJapee@Chris_I_Baker

Our paper details the surgical procedure for virus injection and implantation of the Opto-Array. It also contains many useful details for nonhuman primate surgeries beyond optogenetics. If you have any questions or feedback, we'd love to hear from you!

Opto-Array (@BlackrockNeuro_ ) is an array of μLEDs, used to deliver light to extended regions of the cortex surface for high-throughput behavioral optogenetics in large primate brains. This is a step towards using optogenetics to treat blindness.
