What is the theoretical byte capacity of the brain? How do scientist determine the byte capacity of one neuron?

One estimate brain storage at 1000 terabytes

If the whole body were capable of storing information what would be the storage limit. Remember the neuron activity extends throught the body, read the "Emotional Machine"
Tip for best answer: M$1.00

You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

The exact mechanism of data storage in the brain is still unknown. There are roughly 100 billion neurons in the human brain; if each neuron represents 1 bit of storage, then the brain's capacity would be around 12.5 gigabytes. However, each brain neuron is connected to thousands of other neurons, forming a total of 10^14 to 10^16 synapses between neurons. Each synapse has a variable firing threshold, expanding the potential data storage; and if memory is encoded in synaptic connections, the brain's total storage capacity could be on the order of 500-1000 terabytes, which is the figure you cite in your question. It is also possible that data is stored on a molecular level; in this case, the storage capacity would be orders of magnitude greater than for synaptic storage.

The peripheral nervous system consists of an additional 100 billion or more neurons, about the same number as the brain itself. Assuming whole-body versus brain-only neural memory, this would double the storage capacity of a neuron-based binary storage system from 12.5 to 25 gigabytes. Since most peripheral neurons transmit signals to only a single adjacent neuron, any contribution by the peripheral nervous system to total memory capacity in a synapse-based storage system would add only a tiny fraction to the brain's memory capacity (12.5 gigabytes versus 500-1000 terabytes).

Compared to an average male, an average female brain is smaller, weighs less, so it has less number of neurons and synapses and so on.
Due to all these, does it mean it is less capable, less intelligent?

Intelligence is based more on the ability to integrate data from various parts of the brain than on the size of the brain as a whole. There are known structural differences between male and female brains, which would indicate that either sex may have an inherent advantage over the other when it comes to certain specific tasks.

I'm having doubts about 1 bit per neuron capacity. A neuron is an analog signal processor. Take one analog neuron and look at the classification potential. It is much more that 1 bit.

I think the 1-bit neuron was just used as an example and was not meant as a realistic estimate. A stimulated neuron transmits signals by activating any or all of its synapses, so the maximum data storage per neuron (assuming that data is stored within individual neurons) would be 2^(number of synapses) - 1 bits.

Human brain processing could be between 100 teraflops and 100 petaflops, so a further question is: what is the bus speed?

The brain is one thing but the mind is something else. Awareness is a non-local phenomenon. There are some who would tell you the Universe itself is a single consciousness of which we are a part, in which case the mind's capacity to handle data (to BE data, lol..) would be unlimited.

OK, I see this is the SCIENCE category.. I should delete this, but there is no way to do it, only edit...
