Final answer:
The function of the inner hair cells is not to amplify low sound intensities, but to act as the primary auditory receptors that transduce sound signals into electrical impulses for the brain. The amplification role is attributed to the outer hair cells.
Step-by-step explanation:
The statement regarding the function of the inner hair cells of the organ of Corti is false. The primary role of the inner hair cells is to act as auditory receptors. They are the main transducers for sound signals to electrical impulses which are then sent to the brain via the auditory nerve. These cells do not amplify sound but rather perform the sensory function of transduction. It is the outer hair cells that are primarily involved in amplifying and fine-tuning low sound intensities, thereby helping us discern different sounds and speech in noisy environments. Each hair cell synapses with a number of neurons, relaying detailed auditory information to the brain for processing.
