WebFeb 23, 2024 · Myelin sheath’s primary function is to provide insulation to the axons of the neuron it surrounds. This insulation protects these axons in the same way that electrical wires have insulation. Myelin sheath is a low electrical condenser with high electrical resistance, which means it can act as an insulator without disrupting the electrical ...

Sound waves enter the outer ear (the pinna) and are sent to the eardrum via the auditory … WebAn approach to resolving this dilemma is provided by signal detection theory. This approach abandons the idea of a threshold. Instead, the theory involves treating detection of the stimulus as a decision-making process, part of which is determined by the nature of the stimulus, by how sensitive a person is to the stimulus, and by cognitive factors.

Detection theory or signal detection theory is a means to measure the ability to differentiate between information-bearing patterns (called stimulus in living organisms, signal in machines) and random patterns that distract from the information (called noise, consisting of background stimuli and random activity of the detection machine and of the nervous system of the operator).
