Pathways for naturalistic looking behavior in primate I: Behavioral characteristics and brainstem circuits

M Takahashi, R Veale - Neuroscience, 2023 - Elsevier
Organisms control their visual worlds by moving their eyes, heads, and bodies. This control
of “gaze” or “looking” is key to survival and intelligence, but our investigation of the …

Distinct context-and content-dependent population codes in superior colliculus during sensation and action

EC Ayar, MR Heusser, C Bourrelly… - Proceedings of the …, 2023 - National Acad Sciences
Sensorimotor transformation is the process of first sensing an object in the environment and

Neural encoding of instantaneous kinematics of eye-head gaze shifts in monkey superior Colliculus

AJ van Opstal - Communications Biology, 2023 - nature.com
The midbrain superior colliculus is a crucial sensorimotor stage for programming and

Sensory tuning in neuronal movement commands

MP Baumann, AR Bogadhi… - Proceedings of the …, 2023 - National Acad Sciences
Movement control is critical for successful interaction with our environment. However,
movement does not occur in complete isolation of sensation, and this is particularly true of …

Organizing space through saccades and fixations between primate posterior parietal cortex and hippocampus

ME Vericel, P Baraduc, JR Duhamel, S Wirth - Nature Communications, 2024 - nature.com
The primate posterior parietal cortex (PPC) withholds a unified representation of the visual
space supporting visual exploration, while the hippocampus (HPC) provides a memory …

Perisaccadic perceptual mislocalization strength depends on the visual appearance of saccade targets

MP Baumann, AF Denninger… - Journal of …, 2025 - journals.physiology.org
We normally perceive a stable visual environment despite eye movements. To achieve such
stability, visual processing integrates information across a given saccade, and laboratory …

Microsaccadic suppression of peripheral perceptual detection performance as a function of foveated visual image appearance

J Greilich, MP Baumann, ZM Hafed - Journal of Vision, 2024 - jov.arvojournals.org
Microsaccades are known to be associated with a deficit in perceptual detection
performance for brief probe flashes presented in their temporal vicinity. However, it is still not …
