CANS Exam Verified Questions Answers for Certified Aesthetic Nurse Specialist Preparation Exam Question with 100 Correct Answers 2026
Certified Aesthetic Nurse Specialist Preparation Exam Question Bank 150 for CANS Exam 2026 | Real Exam Solutions which CN location has the most complex discharge pattern? - answer - DCN! (increasing complexity from VCN to DCN) - ex. is fusiform since it has pauser response cells Does the AVCN mimic the response of the AN - answer - yes, primary like & primary like notches ex. spherical and globular bushy Which CN location has T stellate cell physiology? - answer - PVCN - sends axons to TB "chopper" - these cells have intrinsic periodicity - could be from inhibtion! Which reponse type is the most common in the PVCN? - answer - onset locker and onset chopper - highly sensitive to noise and virtually in response to tones at CF What does wideband inhibitor (WBI) in the context of CN stand for? - answer - found in PVCN as the D-stellate cell (sends axons to DCN), the inhibitory inputs that span a broad frequency range, rather than just being tuned to a specific CF. These suppress activity across many frequencies and reduce excitatory outputs from noise. - enhances contrast between Hz What is the term for responsive to or inhibited by a wide range of frequencies? - answer - wideband integration - HF inputs are lateral to the soma - LF inputs are medial to the soma 2 types of rate level functions in the CN - answer - 1. Monotonic: primary reponse (like AN), due to excitation 2. Non-monotonic: non-primary response, tuning to a single SPL, this is due to BOTH excitation and inhibtion example of monotonic - answer - spherical bushy cell example of non-monotonic - answer - octopus cell What is the level coding like in the CN? - answer - CN neurons show excellent DR, with the chopper units being both sensitive at low levels and resisting saturation at high SPLs what are integrators? - answer - These are neurons in the DCN where they "add up" the firing rates of AN fibers, this helps to extend the DR (and overcome the DR problem) what is the dynamic range problem - answer - Auditory nerve fibers have a much smaller dynamic range, typically around 20-40 dB for firing rates before saturation. This means a single fiber can't accurately represent both very soft and very loud sounds. Does the CN have better precision than the AN in terms of temporal coding? - answer - Yes, spikes in the AVCN bushy cells are MORE TEMPORALLY PRECISE than ANF How does the CN work with AM encoding? - answer - The chopper cell in the CN fires at a regular "chopping" rhythm on its own. If you play a sound that AM at the same rate as the cell's natural chopping rate, the neuron will respond strongly. CN tuning curves vary, why? - answer - due to excitation and inhibition in different parts of the TC. - type 1/2: bushy, octo - type 3: chopper - type 4: fusiform is Q10 similar or different when comparing AN and CN responses - answer - similar, but vary by cell types - also some CN neurons (w/ wideband tuning) will respond to entire tonotopic map - others have refined TC w/ inhibtory side bands what do inhibitory side bands do to a CN TC? - answer - creates sharper tuning What is the benefit of lateral inhibition? - answer - Lateral inhibition can sharpen and enhance responses from AN to CN - suppresses neighboring neurons, which makes the signal more distinct and improves contrast between sounds (helps w/ pitch discrimination) Does inhibition have a direct impact on place-based coding along the BM? - answer - yes, it can enchance it!!! - HSR fibers are saturated, LSR peaks barely visible, but once the signal reaches the CN spectral peaks are enchanced due to LATERAL INHIBITION _______ in CN can enhance spectral contrast from the periphery - answer - lateral inhibiton summary of the key differences found across the CN with responses, rate level functions, and TC - answer - What enchances rate based coding and sharpens representations of spectral features? - answer - later
