In the gerbil (Meriones unguiculatus) hippocampal formation, the calcium-binding protein parvalbumin (PV) shows a unique species-specific distribution: it is present in the perforant path from the entorhinal cortex to the stratum molecular of the dentate are and cornu ammonis. A possible relation of this to the seizure-sensitivity of gerbils has been(More)
For primates, as for many other vertebrates, copulation which results in ejaculation is a prerequisite for reproduction. The probability of ejaculation is affected by various physiological and social factors, for example reproductive state of male and female and operational sex-ratio. In this paper, we present quantitative and qualitative data on patterns(More)
Stereotactic coagulations of intralaminar thalamic nuclei in 6 squirrel monkeys Saimiri sciureus produced dark degenerations only of type IV synapses in pallidum externum, according to the classification of Hassler and Chung often preserving the slightly asymmetric contact and subsynaptic densities. Other type IV boutons underwent semidark degeneration,(More)
Pallidum-induced direction-specific movements in squirrel monkeys were studied with stimulation or coagulation of this brain structure. The reactions to pallidum externum stimulation were small rapid and phasic head movements, mainly towards the contralateral side. Stimulation of pallidum internum produced a contralateral turning of the head. After(More)
