Dependence of Retinogeniculate Transmission on Membrane Voltage in the Cat.
The mammalian lateral geniculate nucleus seems organized to gate or control the gain of retinogeniculate transmission, the result of which is then relayed to the visual cortex. We have performed in vivo intracellular studies of retinogeniculate transmission along these retino-geniculo-cortical pathways in cats by recording the retinally evoked excitatory postsynaptic potential (EPSP) in genicul...
متن کاملWave model of the cat tympanic membrane.
In order to better understand signal propagation in the ear, a time-domain model of the tympanic membrane (TM) and of the ossicular chain (OC) is derived for the cat. Ossicles are represented by a two-port network and the TM is discretized into a series of transmission lines, each one characterized by its own delay and reflection coefficient. Volume velocity samples are distributed along the ea...
متن کاملHearing Aid System Using Basilar Hardware Membrane Model
Our purpose is to apply a basilar hardware membrane model (BMM) to hearing-aid systems to solve some of the problem in existing hearing-aid systems. In this study, we construct a BMM using Simulink. Also, we experiment on the response characteristics of our BMM implementation to C6713DSK, using real sounds and hearing-loss sounds, which imitate a hearing-impaired person’s hearing ability. It is...
متن کاملBasilar-membrane Activity and Loudness
Buus and Florentine (ISP meeting 2001) presented evidence that basilar-membrane velocity growth functions are proportional to the square root of loudness functions derived from temporal and spectral integration. Although it is not possible to directly measure basilarmembrane activity in humans, it is likely that tone-burst otoacoustic emission input-output functions, at least at low and moderat...
متن کاملBasilar membrane nonlinearity and loudness.
Loudness matching functions for tones for persons with one shifted-threshold ear (hearing loss and noise-shifted thresholds) and one ear within normal limits were used to derive the presumed basilar membrane (BM) input-output (I/O) function in a normal ear. The comparison was made by assuming that the BM I/O function for the ear with the cochlear threshold shift has a slope of one (a linearized...
