Long ascending projections from substantia gelatinosa Rolandi and the subjacent dorsal horn in the rat. | Small neurons of the substantia gelatinosa Rolandi and the subjacent dorsal horn of the spinal cord have been thought to exert a direct modulatory effect only on neurons located within a distance of a few spinal segemnts. By using the technique of retorograde transport of horseradish peroxidase, however, it has been fo... | 715,454 | [

Long-latency "subthreshold" collicular responses to the constant-frequency components emitted by a bat. | A previously undescribed response pattern has been observed in certain single units in the posterior colliculus of Pteronotus suapurensis. These units, constituting about one-third of those tuned to the region of the dominant constant-frequency (CF) components of the orientation sounds, respond to a tone pip with a bur... | 715,456 | [

Tuning curves and masking functions of auditory-nerve fibers in cat. | Single units of the auditory nerve are maximally sensitive to a given frequency, the so-called characteristic frequency (CF).

An alternative view of the neurobiology of dreaming. | The author critiques the recently proposed activation-synthesis hypothesis about the origin and formation of dreams.
