2. Temporal: Processing at different time scales short timelong time phoneme syllable word sentence paragraph text

3. Receptive field: Visual system receptive field of a neuron: part of the visual field that influences the firing rate of the neuron low-level (sensory) high-level (perceptual, cognitive) M. Bear et al. (2016): Neuroscience: exploring the brain (4th ed.), p. 363

4. Temporal receptive windows same idea as for receptive fields temporally (instead of spatially) distributed TRW = time interval before a response during which stimuli influence the response of the neuron functional implications short TRW ”  ” low-level processing long TRW ”  ” high-level processing

5. green = stimulus pink = no input

6. Two papers TRWs in the visual system Hasson, U. (2008): A Hierarchy of Temporal Receptive Windows in Human Cortex TRWs in the auditory system Lerner, Y. (2011): Topographic Mapping of a Hierarchy of Temporal Receptive Windows Using a Narrated Story

7. Methodology use complex naturalistic stimuli visual: classic silent movies auditory: narrated real-life story different versions forward backward temporally scrambled measure BOLD-signal using fMRI

8. Methodology each condition measured twice correlation between time series calculated (reliability) short TRW: high reliability even if scrambled long TRW: scrambling reduces reliability

12. Summary The brain processes data at different time scales TRW = time interval before response during which stimuli influence the response of the neuron Areas of the brain with TRWs of different lengths have been identified both in the visual and auditory pathways
