Is there any hard-coded memory capacity of our brain?

Question

I am reading Max Tegmark’s book Life 3.0 where he has written

>Your synapses store all your knowledge and skills as roughly 100 terabytes’ worth of information, while your DNA stores merely about a gigabyte, barely enough to store a single movie download.

can we quantify our memory?

In: Biology

Answer 1

We can’t currently quantify memory because we don’t understand how memories are stored in the brain. Only once we understand the physical/biological process of memories can we estimate what the capacity of the brain is. Does each memory get stored in a single neuron? If not, how many neurons does it take? If each memory uses multiple neurons, can several memories overlap and use some of the same neurons? Are memories stored in the links between neurons instead of the neurons themselves? Or is it something completely different, or a combination?
