In our daily life, our sensory systems are detecting various types of information about environments inside/outside of our body which varies from hour to hour. Our movements are well-modulated by utilizing such sensory information which is integrated within our brain. In addition, sensory systems are also associated with reflexes (=involuntary bodily response to some stimuli ) . By utilizing such reflexes, we can prevent from some dangers quickly without thinking. As such, sensory systems play important roles for safe and grateful life.
In this course, we are regarding humans as systems which involve "inputs" and "output", and are learning sensory physiology (structures and functions of various sensors within our body / mechanisms of our perception and cognition) and psychology (how our mental process is associated with our cognition and action). Due to time constraints, we are focusing on somatosensory and visual systems in this course.
