The amount of information that a neuron can receive increases with the number of that the neuron has.

Dendrites

Explanation:

Dendrites are thin and branched extensions, capable of conducting stimuli from other cells (or from environment) and directing them to the cell body, as if they were transmission cables of nerve impulses.

Dendrites extend together with axons throughout the body, connecting neuronal cell bodies to each other and to sensory, glandular, and muscle cells.

Thus, the greater the number of dendrites, the greater will be the amout of information that the neuron can receive.
