Interneurons or association neurons.

Sensory Neurons
Afferent neurons (also called sensory neurons) carry signals to the central nervous system and the brain. Efferent neurons (also called motor neurons) carry signals from the brain.
The SYNAPSE is the very small space between two neurons and is an important site where communication between neurons occurs.
To transmit a signal between neurons.
A synapse, chemical signals called neurotransmitters cross these gaps, carrying on the signal.
A neurotransmitter is released by neurons in order to signal other neurons, muscles, or glands.neurotransmittersneurotransmitters
Not exactly; as an impulse moves from one neuron to another it crosses a small space between the neurons called a synapse. The neurons as said to 'not touch' because the cell MEMBRANES of the two neurons do NOT touch, nor merge, nor consequently is there any sharing of cytoplasm between the two neurons. The two neurons ARE, however, HELD TOGETHER at that synapse by small molecules called SYNAPTIC ADHESION MOLECULES, which protrude FROM each neuron into the synaptic cleft or gap and then stick to one another. In this sense, PARTS of neurons do 'touch' PARTS of other neurons, in a MECHANICAL or structural manner, but NOT in an electrical or signal sense. The neural SIGNAL passes through the synaptic cleft or gap via neurotransmitter chemicals which are released by one neuron, diffuse quickly through the gap, and then stimulate a signal in the receiving neuron.
Chemical. (Called neuro-transmitters.)
Interneurons or association neurons.
No, a reverberating circuit does not involve an incoming signal that travels along a chain of neurons and quickly dies out. A reverberating circuit is a circular circuit that returns a signal to its source.

Interneurons or association neurons are connector neurons that establish connections between other neurons.
