(05) Nov 24, 2014, Processing of visual motion (st)
Which topics were covered in the lecture:
- motion as a fundamental perceptual dimension
- motion as orientation in space-time
- the anatomical localization of motion processing
- the functional anatomy of area MT
- the relationship between a stimulus, the neuronal response to it and the stimulus’ perception
Which topics were covered in the seminar:
- comparing psychometric and neurometric functions in a motion task
- the relationship between the activity of single neurons in area MT and the perception of a moving stimulus
- the effect of electrical microstimulation in area MT on perception
You should be able to answer the following questions after the lecture
- draw a space-time plot of a leftward motion
- draw a polar plot of the tuning curve of a direction-selective cell, tuned to leftward motion
- describe the topographic organization of area MT
- what is meant by a neurometric curve and a psychometric curve (see Newsome et al (1989))?
- why is it interesting to compare these two curves?
- describe the consequences of micro stimulating area MT, as determined by Salzman et al (1990)
- what hypothesis is tested by this microstimulation experiment?
You should know the following terms and concepts after the lecture
- space-time plots for visual motion
- tuning curve
- Reichardt detector
You should know the following terms and concepts after the seminar
- psychometric and neurometric curves
- relationship between the effects of microstimulation and cortical topography
