The human brain contains about 50 billion to 200 billion neurons (nobody knows how many for sure), each of which interfaces with 1,000 to 100,000 other neurons through 100 trillion (10^14) to 10 quadrillion (10^16) synaptic junctions. Each synapse possesses a variable firing threshold which is reduced as the neuron is repeatedly activated. If we assume that the firing threshold at each synapse can assume 256 distinguishable levels, and if we suppose that there are
20,000 shared synapses per neuron (10,000 per neuron), then the total information storage capacity of the synapses in the cortex would be of the order of 500 to 1,000 terabytes. (where 1 terabyte is 1,099,511,627,776 bytes = 1024^4 or 2^40 bytes)

well BM=2500 which is also equal to 250000000kb/.23 which would equal 1086956521.73913048592802147 bytes
