Psychological and Physiological Acoustics: Physiology; Binaural Processing „Poster Session… William P. Shofner, Chairhttp://orbit.dtu.dk/files/4436846/Bj%C3%B8rn%C3%B8.pdf Contributed Papers 3:20 2pAB7. The auditory system as a window onto the processes of prenatal development. Dennis McFadden ~Dept. of Psych. and Inst. for Neurosci., Mezes Hall 330, Univ. of Texas, Austin, TX 78712! Otoacoustic emissions ~OAEs!, auditory evoked potentials ~AEPs!, and hearing sensitivity all exhibit sex differences of several types in humans, and these sex differences are highly similar in newborns and adults. The strong implication is that these differences originate during prenatal development and persist through life. The most parsimonious explanation is that these sex differences are produced by androgenic processes operating on the ear and brain of the developing fetus. Certain special populations of humans have been shown to have OAEs and/or AEPs that differ from the sex-typical values, and again the most parsimonious explanation is that the degree of androgen exposure is the basis for these differences. Certain nonauditory measures from these special populations are in accord with this interpretation. The data from special populations will be summarized and a number of alternative explanations considered. Implications for research on the development of hearing will be discussed. @Work supported by NIDCD.#

Hari Eswaran, James Wilson ~Dept. of Appl. Sci., Univ. of Arkansas at Little Rock, Little Rock, AR 72204!, Hubert Preissl, Pamela Murphy, and Curtis Lowery ~Univ. of Arkansas for Medical Sci., Little Rock, AR 72205! The goal was to successfully record fetal auditory evoked responses ~AERs! using the newly developed noninvasive fetal magnetoencephalographic ~MEG! system called SARA. 131 AER measurements were performed on 31 fetuses starting at 27 weeks. The SARA system, equipped with an array of 151 SQUID ~superconducting quantum interference device! sensors spread over an area of 1300 cm2, is curved to fit the shape of the pregnant abdomen. The auditory stimulus was—1 kHz tone; duration—100 ms; rate—0.5 tones/s.; intensity ~external!—100-dB SPL in air. The data were collected at a sampling rate of 312.5 Hz. The AERs were averaged over a period of 700-ms window after removing interfering maternal and fetal heart signals. Control recordings were performed on the same fetus with the same parameters but without any sound stimulation. The peak of the evoked responses was around 250 ms with amplitudes of about 20 fT. No evident evoked response was seen in the control recordings on the same fetus. In summary, it is feasible to noninvasively acquire MEG auditory evoked responses from the fetus using SARA. AER can be a useful tool for the neurological assessment of fetal well-being throughout gestation. @Work funded by NIH.#

Is this what that schizophrenic Strafor son with coloboma was researching? David McCullar

This is staggering information. A whole new layer. It is beginning to feel like I am actually in a computer matrix.
