Forms of Prediction in the Human Visual System
Save as calendar entryThe idea that predictions shape how we perceive and comprehend the world has become increasingly influential in cognitive, computational, and systems neuroscience. It also forms an important framework for understanding neuropsychiatric disorders. However, the influence of predictions is often exclusively conceptualised in terms of feedback processes, whereby predictions generated in higher-level brain areas exert their influence on lower-level areas within an information-processing hierarchy. This notion excludes from consideration the predictive information that is directly built into the structure of the visual system, and is therefore embedded in the feedforward stream of processing. In my presentation, I will describe a series of computational studies and psychophysical experiments (in both typical observers and patient populations) looking at the role of feedback and feedforward forms of prediction in visual processing. I will conclude that the distinct implementation of each of these forms of prediction in the brain is critical, differentially affecting perceptual performance and representational efficiency.

Arrival by car
Leave the interstate A7 at exit "Göttingen Nord". Follow the B27 straight ahead in the direction of "Braunlage". After the third traffic light intersection turn right towards "Kliniken". Afterwards turn left onto "Robert-Koch-Straße" direction "Universität Nordbereich/Polizei". At the end of "Robert-Koch-Straße" turn right onto "Otto-Hahn-Straße", direction "Nikolausberg". The first street on the left turn onto "Kellnerweg", follow the signs "Deutsches Primatenzentrum".
Arrival by bus
The footpath from the bus stop "Kellnerweg" to the Main Entrance/Reception:
From Bus stop "Kellnerweg" (line 21/22 and 23) Cross the road, go in the direction of the bus. At the mailbox, turn left into the footpath and proceed to the end. Turn right into the Kellnerweg. The main entrance of the DPZ is on the left side.
