Response characteristics of neurons in the medial geniculate body of the little brown bat to simple and temporally-patterned sounds
We examined the auditory response properties of neurons in the medial geniculate body of unanesthetized little brown bats (Myotis lucifugus). The units' selectivities to stimulus frequency, amplitude and duratio...

Effects of GABA-mediated inhibition on direction-dependent frequency tuning in the frog inferior colliculus
Earlier studies from our laboratory have shown that the frequency selectivity of neurons in the frog inferior colliculus is direction dependent. The goal of this study was to test the hypotheses that gamma-am...

Sound direction modifies the inhibitory as well as the excitatory frequency tuning characteristics of single neurons in the frog torus semicircularis (inferior colliculus)
Single-unit recordings were made from the frog inferior colliculus to determine whether or not the direction-dependent sharpening of a unit's free-field excitatory frequency-threshold curve (FTCe) was accompanie...

Neural ensemble coding of target identity in echolocating bats
Most insectivorous bats use echolocation to determine the identity of flying insects. Among the many target features that are so extracted, the insect's wingbeat pattern and frequency appear to serve as useful...

Effects of sound direction on the processing of amplitude-modulated signals in the frog inferior colliculus
Single-unit recordings were made from 143 neurons in the frog (Rana p. pipiens) inferior colliculus (IC) to investigate how free-field sound direction influenced neural responses to sinusoidal-amplitude-modulated...

Neurons with different temporal firing patterns in the inferior colliculus of the little brown bat differentially process sinusoidal amplitude-modulated signals
We examined how well single neurons in the inferior colliculus (IC) of an FM bat (Myotis lucifugus) processed simple tone bursts of different duration and sinusoidal amplitude-modulated (SAM) signals that approxi...

Detection of gaps in sinusoids by frog auditory nerve fibers: importance in AM coding
Physiological studies were carried out in the frog (Rana pipiens pipiens) eighth nerve to determine: (i) whether the modulation rate or the silent gap was the salient feature that set the upper limit of time-lock...

An HRP-study of the frequency-place map of the horseshoe bat cochlea: Morphological correlates of the sharp tuning to a narrow frequency band
The frequency-place map of the horseshoe bat cochlea was studied with the horseradish peroxidase (HRP) technique involving focal injections into various, physiologically defined regions of cochlear nucleus (CN...

Three populations of primary auditory fibers in the bullfrog (Rana catesbeiana): Their peripheral origins and frequency sensitivities
Single unit recordings from the VIIIth nerve of the bullfrog (Rana catesbeiana) in response to tones reveal three populations of auditory fibers: low-frequency inhibitable fibers, mid-frequency non-inhibitable fi...
