on which specific location of the neuron does the summation of graded potentials take place?
axon terminals
axon hillock
dendrites
cell body

Explanation:

Graded potentials are electrical signals in neurons. The axon hillock is the region where these graded potentials are summed up. If the sum reaches the threshold, an action potential is generated. Axon terminals are for neurotransmitter release, dendrites receive signals, and the cell body (soma) has general cellular functions but not the main site for summation of graded potentials to trigger action potentials like the axon hillock.

Answer:

Axon Hillock
