If a postsynaptic neuron is stimulated to threshold by spatial summation this implies that _________.
A) the postsynaptic cell has many synapses with many presynaptic neurons
B) the postsynaptic cell has many voltage gated ion channels
C) the postsynaptic cell has a lower than normal threshold
D) the postsynaptic cell is slow to repolarize
