A neuron can receive thousands of EPSPs from different neurons, and responds by triggering or not triggering an action potential
Korvikt [17]

Answer:

The addition and response to the net effect of postsynaptic potentials is called Spatial summation

Explanation:

Signal summation occurs when impulses received by a neuron are eummed together to reach the excitation threshold to fire a neuron. It occurs at the axon hillock of a neuron. Signal summation occurs since each neuron is connected to many other neurons, often receiving multiple impulses from them, both excitatory and inhibitory.

Signal summation can either be temporal or spatial.

Temporal summation, occurs when impulses received at the same place on the neuron in close temporal succession add up to initiate an action potential in the neuron.

Spatial summation occurs when impulses received simultaneously at different places on the neuron add up to initiate an action potential in the neuron.

How long would it take
Valentin [98]
Solution:
4.2 x 10^6 bp/10^3 bp/seconds         = 4.2 + 103 s which is 4200 seconds and equivalents to 70 minutes

In addition, assuming a pause of 2 seconds for re initiating after completing every okazaki fragment and assuming the okazaki fragments average 1000 nucleotide long.  
4.2 x 10^6 bp/10^3 bp                        = 4200 okazaki fragments                           4200 * 2 seconds                               = 8400 seconds which is 140 minutes or 2 hours 20 minutes of pauses alone.                                                                        

Therefore, overall time would be pauses plus the 70 minutes so total time of 210 minutes. Assuming that the replisome completely disassociates from the DNA after every okazaki fragment and must spend one-minute rebinding.

4200 okazaki fragments. 60 seconds rebinding time per fragment:                        4200 x 1 minute = 4200 minutes rebinding time plus 70 minutes for actual replication. 4200 minutes is 70 hours which is almost 3 days.
