About half of our brain is involved in perceptual processes. Perceptual
processing can in turn be divided into mechanisms of measurement and
inference. Research on how the brain detects sensory signals and extracts
or measures simple features from the sensory imput has already revealed a
very detailed picture of early sensory processing. However, how perception
emerges from these simple features is still largely unclear. Taking visual
perception as an example, we look at inference mechanisms that allow us to
build a model of our visual environment. Among other things, we will deal
with the question of how single features turn into a perception of
surfaces, objects and dynamic events in a 3-dimensional world and how the
brain fills in missing information, which can then be perceived. Moreover,
in this seminar we will also explore how we can distinguish visual
inference from cognitive inference which will allow us to address
questions regarding the large scale architecture of the human mind. |
