Assume the following:
- there are at least 10^11 neurons in the human brain
- there are approximately 10^14 synaptic connections in the human brain (because on average each neuron gets inputs from approximately 1000 other neurons)
- synaptic delay is approximately 1-2ms (but for the sake of it we can also assume an order of magnitude less, so 0.1ms)
A problem that revealed itself to me: It would "only" take 1000 (or 10000 if we use 0.1ms as synaptic delay) serial synaptic connections in order to generate a lag of 1s. Considering that there are 10^11 neurons in the brain, the number of neurons you need firing sequentially in order to generate significant lag (>1s) seems tiny compared to the overall amount of neurons in the brain.
My questions: Are there series of neurons (firing from the time of input to the time after processing) greater than 1000 (or 10000)? How are there series (not) greater than 1000 (or 10000) neurons?
P.S. I'm talking about chemical synapses which I assume to make up the bulk of neural transmission in this case
