DOI: 10.1016/j.cub.2020.06.023
Abstract: Motion vision is important in guiding animal behavior. Both the retina and the visual cortex process object motion in largely unbiased fashion: all directions are represented at all locations in the visual field. We investigate… read more here.

DOI: 10.1016/j.neuroimage.2018.04.071
Abstract: &NA; We explored anatomical details of the superior colliculus (SC) by in vivo magnetic resonance imaging (MRI) at 9.4T. The high signal‐to‐noise ratio allowed the acquisition of high resolution, multi‐modal images with voxel sizes ranging… read more here.

DOI: 10.1038/s41398-018-0315-3
Abstract: The prosocial hormone oxytocin (OXT) has become a new target for research on the etiology and treatment of autism spectrum disorder (ASD), a condition characterized by deficits in social function. However, it remains unknown whether… read more here.

DOI: 10.1038/s41467-018-08058-0
Abstract: In patients with damage to the primary visual cortex (V1), residual vision can guide goal-directed movements to targets in the blind field without awareness. This phenomenon has been termed blindsight, and its neural mechanisms are… read more here.

DOI: 10.1038/s42003-019-0527-y
Abstract: The superior colliculus (SC) is an excellent substrate to study sensorimotor transformations. To date, the spatial and temporal properties of population activity along its dorsoventral axis have been inferred from single electrode studies. Here, we… read more here.

DOI: 10.1093/cercor/bhx161
Abstract: In the auditory cortex (AC), corticofugal projections arise from each level of the auditory system and are considered to provide feedback "loops" important to modulate the flow of ascending information. It is well established that… read more here.

A deep neural network model of the primate superior colliculus for emotion recognition

DOI: 10.1098/rstb.2021.0512
Abstract: Although sensory processing is pivotal to nearly every theory of emotion, the evaluation of the visual input as ‘emotional’ (e.g. a smile as signalling happiness) has been traditionally assumed to take place in supramodal ‘limbic’… read more here.

DOI: 10.1111/epi.17469
Abstract: Decades of studies have indicated that activation of the deep and intermediate layers of the superior colliculus can suppress seizures in a wide range of experimental models of epilepsy. However, prior studies have not examined… read more here.

DOI: 10.1152/jn.00077.2020
Abstract: The primate superior colliculus (SC) is causally involved in microsaccade generation. Moreover, visually-responsive SC neurons across this structure's topographic map, even at peripheral eccentricities much larger than the tiny microsaccade amplitudes, exhibit significant modulations of… read more here.
