The human brain is EXTREMELY "multi-threaded" as it is , it can process about 11 million pieces of information per second; the reason why we don't notice it is because only about 40 of those reach our consciousness and the signals we do recieve have already been processed into something that is easier to understand.
One obvious example of "multi-threading" is that we have separate processes for each of our senses, e.g. you do not need to make a conscious effort to combine the two signalks that comes from your eyes into one picture; there is a separate "thread" that does this for you.
