Despite their simple auditory systems, some insect species recognize certain temporal aspects of acoustic stimuli with an acuity equal to that of vertebrates; however, the underlying neural mechanisms and coding schemes are only partially understood. In this study, we analyze the response characteristics of the peripheral auditory system of grasshoppers(More)
The temporal resolution of auditory receptors of locusts was investigated by applying noise stimuli with sinusoidal amplitude modulations and by computing temporal modulation transfer functions. These transfer functions showed mostly bandpass characteristics, which are rarely found in other species at the level of receptors. From the upper cut-off(More)
186 There is a well-documented relationship between short sleep duration and high body mass index (BMI). In the largest study, a survey on sleep duration and frequency of insomnia in more than 1.1 million participants, increasing BMI occurred for habitual sleep amounts below 7–8 hours [1]. A recent prospective study found an association between sleep(More)
In hearing insects, discrimination of auditory signals is vital to mate selection. We tested the capability of single auditory receptor neurons to discriminate calling songs from di!erent individual grasshoppers of the same species. Spike trains elicited from di!erent songs were studied using the metric-space analysis of Victor and Purpura (Networks:(More)
Our study examined 166 patients with breast cancer with a mean age of 63 years. Each patient underwent mastectomy with the organ being investigated by histological giant sections and additional small sections from the nipple. Nipple involvement was found in 64 cases (38%). Multifocal carcinoma occurred in 76 patients. Further multicentric carcinomatous foci(More)
