In natural acoustical environments, most biologically related sounds containing frequency-
modulated (FM) components repeat over periods of time. They are often in rapid sequence …

Speech and other communication signals contain components of frequency and amplitude
modulations (FM, AM) that often occur together. Auditory midbrain (or inferior colliculus, IC) …

Both animal communication sounds and human speech contain frequency-modulated (FM)
sweeps. Although the selectivity for the rate of FM sweeps in neurons has been found in …

A periodic sound, such as a pure tone, evokes both transient onset field-potential responses
and sustained frequency-following responses (FFRs) in the auditory midbrain, the inferior …

In order to explore the possible mechanisms by which ethologically relevant sounds can be
extracted from complex auditory environments, this study examined the effects of weak noise …

This study examined the effect of sound direction on frequency tuning of inferior collicular
(IC) neurons of mice under free field stimulation conditions. Fewer than 20% of IC neurons …

Receptive fields of single units in the auditory midbrain of anesthetized rats were studied
using random FM-tone stimuli of narrow frequency-ranges. Peri-spike averaging of the …

Single units were recorded from the inferior colliculus (IC) of anaesthetized rats in response
to:(a) an FM tone, the frequency of which was randomly varied, and (b) a digitized rat …

Species-specific vocalizations in mice have frequency-modulated (FM) components slower
than the lower limit of FM direction selectivity in the core region of the mouse auditory cortex …

Frequency modulations occur in many natural sounds, including vocalizations. The neuronal
response to frequency modulated (FM) stimuli has been studied extensively in different brain …
