Similarities Between Presynaptic Neuron and Postsynaptic Neuron
As Presynaptic Neurons and Postsynaptic Neurons are different from each other, still they have a lot of common things. Here’s some of the similarities between Presynaptic Neurons and Postsynaptic Neurons:
- Both presynaptic and postsynaptic neurons rely on neurotransmitters for communication. The presynaptic neuron releases neurotransmitters into the synaptic cleft, while the postsynaptic neuron receives these neurotransmitters.
- Both presynaptic and postsynaptic neurons collectively form a chemical synapse, where information is transmitted from one neuron to another through neurotransmitter release and reception.
- Both presynaptic and postsynaptic neurons play essential roles in nerve impulse transmission. The presynaptic neuron initiates the transmission by releasing neurotransmitters, and the postsynaptic neuron receives the message by binding to these neurotransmitters.
- Both presynaptic and postsynaptic neurons are affected by the opening and closing of calcium channels. In the presynaptic neuron, calcium channels open upon depolarization, leading to neurotransmitter release. In the postsynaptic neuron, calcium channels are involved in depolarization upon binding of neurotransmitters.
- Both presynaptic and postsynaptic neurons possess specific receptors on their membranes that interact with neurotransmitters during the transmission process.

Difference Between Presynaptic Neuron and Postsynaptic Neuron
Difference Between Presynaptic Neurons and Postsynaptic Neurons: Presynaptic Neurons and Postsynaptic Neurons are two neurons that are involved in forming chemical synapses for the transmission of impulses between two neurons. The major difference between a presynaptic neuron and a postsynaptic neuron is that the presynaptic neuron is involved in transmitting a message to the synaptic cleft by releasing neurotransmitters while the postsynaptic neuron is involved in receiving the message from the synaptic cleft by taking up neurotransmitters from the cleft.
In this article, you will study the Difference between Presynaptic Neuron and Postsynaptic Neuron, along with their similarities.
