What property of neurons allows them to respond to changes in the environment?

Neurons possess the property of excitability, which allows them to respond to changes in the environment by generating and transmitting electrical signals called action potentials. This excitability is facilitated by the presence of specialized ion channels in their membranes, enabling them to detect stimuli and convert them into electrical impulses. Additionally, the synaptic connections between neurons facilitate communication and integration of information, allowing them to react to various environmental changes.
