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

Spatial summation occurs when multiple presynaptic neurons release neurotransmitters simultaneously, therefore adding up their effects to reach threshold in the postsynaptic neuron. Therefore, if a post synaptic neuron is stimulated to threshold by spatial summation, it implies that the postsynaptic cell has many synapses with many presynaptic neurons.
