Television presents 25
images in one second. Yet we see it as continuous because there is an after
image in our brain that lasts one-eleventh of a
second. Is there a similar after
image in the sense of smell?
Yes. Though the experiments
showed that rat brains respond to
smells in a few milliseconds.,
Even after removal of the
smell, there is an after image that
lasts for more than 10 breath cycles. They have also identified
the particular brain area that is responsible for this phenomenon.
