The ABR wave forms of 16-day-old and adult Mongolian gerbils were evoked by click stimuli presented at rates ranging from 1 to 80/sec. Wave I and wave IV thresholds were determined for each of 5 click rates. Amplitudes and latencies of waves I and IV were measured at each of 7 click rates and 3 intensity levels (15, 40 and 65 dB above threshold). Thresholds for waves I and IV in the adult gerbi...

Experiments were performed on cats under Chloralose or Nembutal anesthesia. The parameters of the acoustic click stimuli were found to have a strong influence on the responses registered from both the surface of the cerebellar vermis lobuli V up VII as well as from single units. It was shown that a stimulus frequency rate not greater than 1/2 s should be used, since higher frequencies caused st...

The intracortical distribution of evoked potentials was studied by seven-contact multielectrodes implanted into the primary auditory cortex of freely moving cats. The aim of the study was to compare the intracortical profiles of the responses evoked by click stimuli and by electrical stimulation of the medial geniculate body in different states of alertness and in Nembutal anesthesia. Only the ...

Often ABR threshold testing employs clicks to assess high-frequency hearing, and low-frequency tone bursts to assess low-frequency sensitivity. While a maturation effect has been shown for click stimuli, similar data are lacking for low-frequency toneburst stimuli. Thus, 305 infants ranging in conceptional age (CA) from 33 weeks to 74 weeks were tested. Absolute latencies were measured for wave...

Abstract In this review article, we survey the 2016–June 2021 scientific literature on synthesis of multi‐stimuli responsive (MSR) polymers, main focus being reversible deactivation radical polymerization techniques (RDRPs, also known as controlled polymerizations). fact, along more than 40 years extensive research, RDRPs have boosted stimuli‐responsive polymers. are now robust, versatile, rela...

Evidence regarding the functional subdivisions of human auditory cortex has been slow to converge on a definite model. In part, this reflects inadequacies of current understanding of how the cortex represents temporal information in acoustic signals. To address this, we investigated spatiotemporal properties of auditory responses in human posterolateral superior temporal (PLST) gyrus to acousti...

Abstract Objective The aim of the study was to evaluate effects narrow band level-specific Claus Elberling-Chirp (NB LS CE-Chirp) and CE-Chirp stimuli on amplitudes, latencies, interpeak latencies in comparison with tone burst (TB) click. Methods A total 40 ears (10 males, 10 females; age range: 20–26) individuals who had no complaints related hearing participated study. Differences between cli...

This paper continues a line of research initiated by Kaernbach and Demany [J. Acoust. Soc. Am. 104, 2298-2306 (1998)], who employed filtered click sequences to explore the temporal mechanism involved in the pitch of unresolved harmonics. In a first experiment, the just noticeable difference (jnd) for the fundamental frequency (F0) of high-pass filtered and low-pass masked click trains was measu...
