as well as converging ones. Much of the
processing appears to be distributed,
parallel, and specialized.!
V1 responsive to orientation of a line of light. But then what happens is you have a bunch of neurons which different orientations, and they may converge to a
single neuron at the next level, say V2, and that neuron is response to more complex aspects. Further you go, the more complex the info is that the neuron is
responding too. Tend to have convergence, thus receptive ﬁelds tend to get bigger and bigger. Turns out it is not that simple: the V1 has a lot diverging pathways
as well (and also feedback loops). Have areas paralleling other aspects such as shape, emotion aspect, etc. All must come together to form our visual and Multimodal Integration!
The brain integrates multiple inputs from different sensory modalities, such as sight,
sound, touch, smell, etc., into the perception of a uniﬁed multisensory experience. ! The McGurk Effect: the p...
