Precise Temporal Processing in the Gerbil Auditory Brainstem
… in vivo recordings from the MSO of the Mongolian gerbil, the present study showed that the responses of ITD-sensitive neurons are inconsistent with the idea of a topographic map of auditory space. Moreover, whereas the maxima of ITD functions were found to be outside, the steepest slope was …

Anatomical identification of primary auditory cortex in the developing gerbil
… development is an active field of study. The gerbil provides an excellent model for research because at the moment of birth its brain is rather immature, anatomically and functionally. Furthermore, the gerbil auditory cortex is particularly amenable to investigation in that the gerbil's onset …

Supra-Characteristic-Frequency Response in Gerbil Auditory Nerve Frequency Tuning Curves
… (CF). We recorded ANF responses from the gerbil, concentrating on this supra-CF region. We observed a supra-CF plateau in ANF responses at high stimulus level, indicating that the plateau mode of BM motion can be excitatory. Quantitative aspects of our findings suggest that the …

In-vivo measurement of sound-induced motions in the gerbil cochlea
… the basilar membrane (BM) in the Mongolian gerbil at a distance of roughly 1.5 mm from the extreme base and found a best frequency (BF) of roughly 35 kHz. We chose the base to gain access through the round window membrane (RWM) to minimize the need for invasive surgery. Post-mortem …

Measurements and models of electrically-evoked motion in the gerbil organ of Corti
A cell with extraordinary motile ability exists in our inner ear, the outer hair cell. Outer hair cell (OHC) motility can occur at acoustic frequencies and play a key role in mammalian cochlear frequency selectivity and hearing sensitivity. To date, the mechanism of cochlear amplification is not …

Patterns of intraspecific and intergeneric agonistic behavior in the male and female Mongolian gerbil (<i>Meriones unguiculatus</i>)
… agonistic patterns of behavior of the adult male gerbil (<i>Meriones unguiculatus</i>) have been examined in previous work, the behavior of the female gerbil has not been given careful examination. Understood to an even lesser extent is the plasticity of the agonistic response in terms of …

Mechanisms of inhibition and neuronal integration for signal processing in the primary auditory cortex of the Mongolian gerbil (Meriones unguiculatus)
… the auditory cortex of the lightly anaesthetized gerbil (Meriones unguiculatus). Bicuculline generally increased the spontaneous neuronal activity and enhanced and prolonged onset responses to sound. Application of bicuculline often resulted in a shift of the most sensitive frequency of the …

The Structure-Function Relationship of Prestin: from an Evolutionary Perspective
… species (zebrafish, chicken, platypus and gerbil), to gain insight regarding how these two physiological functions might have distinctly evolved. Somatic motility, voltage-dependent NLC and transporter function were measured in transfected human embryonic kidney (HEK) cells using …

Sex differences in the actions of psychoactive agents and progesterone on anxiety-related behaviour in the mongolian gerbil (meriones unguiculatus) and the effects of corticosterone on the hippocampal morphology of wistar rats (rattus norvegicus)

Seed dispersal by black-backed Jackals (Canis mesomelas) and hairy-footed gerbils (Gerbillurus spp.) of !nara (Acanthosicyos horridus) in the central Namib Desert
… seed dispersal by scatter-hoarding hairyfooted gerbils (Gerbilliscus (Gerbillurus) spp.) in the central Namib Desert. This was accomplished by examining visitation rates and fruit removal of !nara melons, primarily by jackals. In addition, I determined the viability and germination rate of !nara …

Sound-induced micromechanical motions in an isolated cochlea preparation
