    Notes: Summary In 4 dorsolateral thalamic nuclei (LA, DLAmc, DLLd and DLLv) short latency evoked responses were recorded after electrical or photic stimulation of the contralateral eye. Electrical stimulation of these 4 nuclei led to bilaterally evoked responses in the wulst, where previous experiments had demonstrated an oligosynaptic projection from the retina. Cooling in DLL, while stimulating the contralateral optic nerve, leads to a severe decrement of both wulst responses suggesting that the thalamus functions as a relay within the retino-thalamo-hyperstriatal pathway. When the optic nerve ipsilateral to the cooled thalamus is stimulated the ipsilateral wulst response is unchanged while the contralateral wulst response is enhanced, suggesting a disinhibition. Similarly an inhibitory effect of the thalamus on one side upon the contralateral wulst response was found after concomitant stimulation of one optic nerve and a delayed stimulation of the ipsilateral thalamus. The dorsolateral thalamic group is the origin of bilateral wulst projections, the pathway to the contralateral telencephalon was demonstrated to pass via the supraoptic decussation DSO. Cooling DSO diminished the inhibitory thalamic effect upon the contralateral wulst. DSO was corroborated as part of the ipsilateral retino-wulst system.

    Notes: Summary 1. The distribution of labeled macromolecules was studied within the dorsolateral thalamic nuclei of the pigeon after unilateral intraocular injection of either 3H-proline, 3H-leucine or 3H-fucose. The highest densities of grains were found in nucleus dorsolateralis anterior, pars lateralis at its dorsolateral aspect (DLLd) and in nucleus lateralis anterior (LA) whereas moderate labeling was observed in the ventral aspect of DLL (DLLv) and in nucleus dorsolateralis anterior, pars magnocellularis (DLAmc). No significant label was found on the ipsilateral side. 2. After circumscribed unilateral ablation of the visual wulst, the cells in DLLv were most severely affected by retrograde degeneration, whereas DLLd, DLAmc and LA remained intact. Bilateral ablation of the wulst or combination of wulst damage with section of the supraoptic decussation gave rise to additional degeneration in DLLd, thus suggesting a contralateral retinotelencephalic pathway via DLLv and an ipsilateral retino-telencephalic pathway via DLLd and recrossing via DSO. LA and DLAmc represent relays in retinothalamo-telencephalic pathways of unknown destination. 3. DLLv was confirmed as relay in the contralateral retino-thalamo-hyperstriatal pathway in a combined series of experiments, where the autoradiographic and the retrograde degeneration techniques were applied in the same animal.

    Pair-breaking effects in the superconducting Kondo alloy LaCe (1971)

    Notes: Abstract The depression of the superconducting transition temperature of LaCe alloys and the upper critical fieldH c2 (T) of La and LaCe was measured, down to 0.05 K. The results disagree with calculations, based on recent theories, including the temperature dependence of the spin-flip amplitude.

    Crystalline field effects in superconducting La1−xTbxAl2 under pressure (1974)

    Notes: Abstract The pressure dependence of the superconducting transition temperature of LaAl2 and alloys with Tb and Gd impurities has been measured. The results are compared with a theoretical calculation of the pressure dependence ofT c , which is based on the variation by pressure of the crystalline field experienced by the Tb ions. Measurements onLaGdAl2 where crystal field effects are absent have been used to study the influence of pressure on the scattering rate.
