There are two kinds of neurotransmitters - INHIBITORY and EXCITATORY. Excitatory neurotransmitters are not necessarily exciting - they are what stimulate the brain. Those that calm the brain and help create balance are called inhibitory. Inhibitory neurotransmitters balance mood and are easily depleted when the excitatory neurotransmitters are overactive.

An EPSP is an excitatory postsynaptic potential, which represent input coming from excitatory cells, whereas an inhibitory postsynaptic potential represents input driven by inhibitory presynaptic cells.
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.
The type of neurotransmitter.
The excitatory or inhibitory inputs from cerebrum.
Depending on the effector organ it can be inhibitory or excitatory. The muscarinic receptors are activated from the parasympathetic nervous system. So the effect of muscarinic receptors activated on the heart, it will slow the heart down. However, on the gastrointestinal tract, it will increase motility.
Excitatory neurotransmitter usually is acetylcholine. To get inhibitory responses in a nerve cell, the arrangement of receptors is different. The study of nervous system in detail will provide you exact answer to your question.
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.
