Spatial summation occurs when multiple presynaptic neurons release neurotransmitters into the synapse, and if the combined effect reaches the threshold, an action potential is triggered in the postsynaptic neuron.
التجميع المكاني يحدث عندما تفرز عدة عصبونات أمام المشبك نواقل عصبية تتجمع في المشبك، وإذا وصلت إلى العتبة، يتم تحفيز جهد فعل في الغشاء التالي.
