Prenatal augmented auditory stimulation and visual system development: Effects of timing on intersensory organization

This study investigated the effects of augmented prenatal auditory stimulation on postnatal visual responsivity and neural organization in bobwhite quail (Colinus virginianus). I delivered conspecific embryonic vocalizations before, during, or after the development of a multisensory, midbrain audiovisual area, the optic tectum. Postnatal simultaneous choice tests revealed that hatchlings receiving augmented auditory stimulation during optic tectum development as embryos failed to show species-typical visual preferences for a conspecific maternal hen 72 hours after hatching. Auditory simultaneous choice tests showed no hatchlings had deficits in auditory function in any of the groups, indicating deficits were specific to visual function. ZENK protein expression confirmed differences in the amount of neural plasticity in multiple neuroanatomical regions of birds receiving stimulation during optic tecturn development, compared to unmanipulated birds. The results of these experiments support the notion that the timing of augmented prenatal auditory stimulation relative to optic tectum development can impact postnatal perceptual organization in an enduring way.^

Mean current and temperature data from the Gulf of Cádiz

During "Meteor" cruise 23 in spring 1971 intensive investigations of the Mediterranean outflow in the Gulf of Cidiz were carried out. In order to give a budget of the inflow and outflow numerous CTD-stations were taken. The observations also included six moored current meter arrays deployed in the known outflow channels. The considerations given here are based mainly on three hydrographic sections, current meter records averaged over one month, and geological observations from the bed forms beneath the Mediterranean undercurrent. The results show that the outflow essentially is determined by the bathymetry of the area. At least four separate outflow channels could be confirmed. The volumentric transport rates of three of them were calculated. These channels are the northerly near shelf branch (0.40 * 10**6 m**3 * sec**-1), the main branch (1.39 * 10**6 m**3 * sec**-1) in southwesterly direction, and an intermediate branch (0.24 * 10**6 m**3 * sec**-1) found between both. In a static box model the progressive mixing of 0.95 * 10**6 m**3 * sec**-1 pure Mediterranean Water with 1.97 * 10**6 m**3 * sec**-1 North Atlantic Central Water is demonstrated.
