An inhibitory postsynaptic potential (IPSP) is a kind of synaptic potential that makes a postsynaptic neuron less likely to generate an action potential.
synaptic potential
The voltage-gated Ca2+ channels are opened when an action potential releases neurotransmitters from a neuron. A neuron transmits nerve impulses.
The excitatory or inhibitory inputs from cerebrum.
Neurons integrate incoming signals and sum up the excitatory and inhibitory signals, integration. The excitatory neurotransmitter produces a potential change (signal). This signal pushes the neuron closer to an action potential. If the neuron receives excitatory signals chances are that the axon will transmit a nerve impulse. The inhibitory neurotransmitter produces signals that drive neurons further from an action potential. If neurons receive both the inhibitory and the excitatory signals the summing of the signals may prohibit the axon from firing.

In general, action potentials that reach the synaptic knobs cause a neurotransmitter to be released into the synaptic cleft. The arrival of the action potential opens voltage-sensitive calcium channels in the presynaptic membrane.

During decision-making, information is processed to choose between two or more alternatives. This involves the interaction of excitatory and inhibitory neurons. This process also involves excitatory and inhibitory neurotransmitters. The post-synaptic action potential is determined by the sum of all signals.
... Depends entirely on the post-synaptic neuron. If it is an inhibitory synapse (often located on the actual body of the dendrite or soma), then the probability of that post-synaptic neuron firing DECREASES. The reverse is true if it is excitatory; the synapse (more likely located on a dendritic spine) will more likely induce the post-synaptic neuron to fire an action potential.
Chemically Gated Channels.
The synaptic transmission is where the communication between the terminal button and the dendrite occur. What happens is the impulse moves along the axon and release neurotransmitter from the end plate of the presynaptic neuron and are diffused across the synaptic cleft. This creates a depolarization of the dendrites of the postsynaptic neuron. When that happens the postsynaptic's sodium channels to open and start the action potential. Once the channels are open an enzyme called cholinesterase is released from postsynaptic membrane and it acts to destroy the neurotransmitters. When they are destroyed the sodium channels close and begins recovery.
