Final answer:
Spike-triggered averaging is a technique used in neurophysiology to measure neuronal forces. The leech model is used to observe and study neuronal activity. It provides insights into the functioning of the nervous system.
Step-by-step explanation:
Spike-triggered averaging is a technique used in neurophysiology to measure neuronal forces. It involves identifying the electrical signals produced by neurons and analyzing their patterns. By measuring the spikes or action potentials of neurons in response to certain stimuli, researchers can determine the forces exerted by the neurons. The leech model is often used as its neuronal activity can be easily observed and studied in the lab. This technique provides valuable insights into the functioning of the nervous system.
