    Notes: Summary A 46-year-old woman presented acute sensori-motor neuropathy of the Guillain-Barré type, followed by a protracted course of profound autonomic and sensory dysfunction. Tests of autonomic functions showed denervation hypersensitivity. Neuropathologically, the trigeminal sensory nuclei, solitary nucleus, the dorsal columns of the spinal cord and dorsal spinal roots showed severe degeneration. Degeneration was found both in the preganglionic (intermediolateral cell columns of the spinal cord) and postganglionic (sympathetic ganglion and celiac ganglion) neurons of the sympathetic nervous system, and the preganglionic (dorsal motor nucleus of the vagus) and postganglionic (Auerbach's plexus) neurons of the parasympathetic nervous system.

    Notes: Summary Monkeys were trained to perform a fixation task and a visual discrimination task. During the fixation task, one or two light bars were presented at different positions in the receptive fields of TE neurons. During the discrimination task, the animal was required to detect the positive stimulus when one or two of the paired small colored spots or two-dimensional patterns were presented. In both behavioral conditions, when the two light stimuli were presented simultaneously, almost none of the TE neurons showed an increase in responding over the single stimulus condition; the response was usually similar or less than the stronger response in the single stimulus condition. In the neurons that responded selectively to the discriminanda during the discrimination task, various interactions between the two antagonistic stimuli occurred depending on the location or the effectiveness of the two stimuli. These results may be related to gain control mechanisms in the wide receptive fields of TE neurons.
