Seminar with Alexander Heimel and Jonathan Whitlock
"Interactions between an old and a new visual system in the mouse" by Alexander Heimel (Netherlands Institute for Neuroscience).
"Parietal and pre-motor areas encode 3D pose in freely behaving rats" by Jonathan Whitlock (Kavli Institute for Systems Neuroscience, NTNU).
Alexander Heimel: "Interactions between an old and a new visual system in the mouse"
When we see, we use our cerebral cortex. There are also numerous connections from the retina to the superior colliculus, an evolutionary older visual center in the midbrain. In humans and other primates, the superior colliculus is involved in directing gaze in attention. In the mouse, it is also responsible for initiating many other visually guided innate behaviors. In this talk, I will present our results on the two way traffic of information between these two visual centers.
Jonathan Whitlock: "Parietal and pre-motor areas encode 3D pose in freely behaving rats"
All members of the animal kingdom live and must survive in a three-dimensional world, whether their habitat is on land, in the sea or air, and how the brain coordinates movement in 3D has been a topic of investigation for years. Here, we recorded from posterior parietal cortex and frontal motor cortex while tracking freely running rats in 3D, and found that the majority of cells in both areas robustly encode 3D posture. The data provide a first-time view of how associational and motor areas cooperate to represent 3D behavior in freely moving individuals.
