Answer:
When neurotransmitter molecules bind to receptors located on a neuron's dendrites, voltage-gated ion channels open. At excitatory synapses, positive ions flood the interior of the neuron and depolarize the membrane, decreasing the difference in voltage between the inside and outside of the neuron.
Explanation:
Positive ions flow into a neuron and depolarize its membrane when a
neuron is activated.
What is a Neuron?
Neurons are also referred to as nerve cells and they help to send and
receive signals from the brain.
Positive ions such as Sodium ions flood the interior of the neuron and
depolarize the membrane, in the excitatory synapse. When this occurs, the
voltage difference between the inside and outside of the neuron is
reduced.
