What do dendrites do in the context of a neuron?

Dendrites play a crucial role in the functioning of neurons by serving as the primary receiving structures for signals from other neurons. They are tree-like extensions that increase the surface area of the neuron, allowing it to receive and integrate a greater amount of information from surrounding cells.

In this context, the correct choice focuses on their ability to connect to other neurons. Dendrites receive neurotransmitters released by neighboring neurons at synapses, which can lead to the generation of electrical impulses if the signal is strong enough. This connection is fundamental to the communication within the nervous system, enabling the intricate networks that contribute to sensory processing, reflexes, and higher brain functions.

While the other options relate to neuronal functions, they do not accurately describe the specific role of dendrites. Carrying nerve impulses is primarily the role of the axon. Detecting stimuli generally pertains to specialized sensory receptors. Processing information often involves the cell body and the interplay of multiple neuronal components, where dendrites contribute but are not solely responsible.
