[neuroscience]Is there any limit as to how much information that the human brain can hold?

Is there any theoretical limit as to how much information that the human brain can hold?

What would happen if someone reached that limit?

Ultimately the brain has limited amount of material for data storage so it can store limited amount of information. It is impossible to store infinite information to finite possible entropy. However the brain also does not store the information in quite the same way than a computer does. Information in the brain often needs refreshing and unimportant things tend to fade in memory. Probably because same "circuits" are used to store other things too. 

Think of it like in artificial neural network classification in machine learning. You can teach it to classify a class but if you then stop showing it that class and feed it data about other classes the network might get modified in a way that the first class is no longer reliably recognized. 

I am not aware of anyone hitting the limit of their memory capacity though. And it's good to remember that even the most informed answers you get in the neuroscience field involve a lot of "informed opinions" instead of hard fact.
