We have a new paper just published in Scientific Reports! In this new paper, we tackled the question of whether superior colliculus (SC) neurons have an ability to detect visual objects in their very initial spiking responses to image onsets (occurring within ~50 ms from presenting a visual stimulus to the eyes). It has long[…]
Our lab members are in Washington, DC this week to present their latest work on active vision, with a focus on how the primary visual cortex (V1) relates to the midbrain superior colliculus (SC) when it comes to generating rapid saccadic eye movements. Comparison of the physiological properties of visual responses in primary visual cortex[…]
We have a new paper now published in the Journal of Neurophysiology! In it, we continued our studies of visual interruption. During natural visual behavior, we continuously generate saccadic eye movements. Whenever a visual transient occurs in the environment, the likelihood of saccade generation suddenly drops to almost zero within less than 100 ms from[…]
We have a new and exciting paper now published in the Proceedings of the National Academy of Sciences! In this paper, we tackled one of the most classic notions in systems neuroscience: that superior colliculus (SC) neurons in the midbrain issue a motor command that triggers and controls the trajectories of rapid eye movements (called[…]
Our lab is represented at this year’s junior neuroscientists’ conference by Carlotta Trottenberg! She presents updates on our work relating visual detection of stimuli and variability in saccadic reaction times. Carlotta explored visual responses of neurons in the primary visual cortex (V1) and superior colliculus (SC), and she related how different parameters of visual responses[…]
Our lab participated in this year’s European Conference on Visual Perception (ECVP), taking place in Cyprus. The conference has a long tradition, being organized since more than 40 years. At this year’s conference, we tackled the neurophysiological mechanisms associated with slow ocular position drifts. These are tiny, slow changes in eye position (even smaller than[…]
We have a new paper just published in the Journal of Neuroscience. In this paper, we investigated visual field anisotropies, but specifically when visual stimuli appeared in the temporal vicinity of rapid saccadic eye movements. Past work has shown that visual perceptual performance is either the same or significantly better (depending on the stimulus conditions)[…]
At the end of the systems vision summer school that our lab contributed to recently, there was a very interesting and multidisciplinary research symposium. The symposium covered different aspects of vision and with a variety of techniques. There were talks related to theory, psychophysics, brain imaging, neurophysiology, computational models, and even pictorial art. Our lab[…]
Our lab contributed to this year’s Systems Vision Science Summer School in Tübingen. Our contribution was led by Carlotta Trottenberg, Matthias Baumann, and Tong Zhang, and it covered our experiments on the active vision loop (image below), with a focus on the superior colliculus (the topic of choice for our session at the summer school).[…]
Our lab is participating in this year’s Gordon Research Conference (GRC) on Eye Movements. This is the first time that this special conference takes place since 2019, so it feels even more special than it already is! The conference brings together a group of experts on different aspects of eye movement research, from sensation to[…]
