After limited sensory deafferentations in adult primates, somatosensory cortical maps reorganize over a distance of 1 to 2 millimeters mediolaterally, that is, in dimension along which different body parts are [...]

We trained monkeys (Macaca mulatta) to perform a delayed-response task in which the animals had to remember briefly the location of a figure after it had been removed from the [...], The brain frequently needs to store information for short periods. In vision, this means that the perceptual correlate of a stimulus has to be maintained temporally once the stimulus has been removed from the visual scene. However, it is not known how the visual system transfers sensory information into a memory component. Here, we identify a neural correlate of working memory in the monkey primary visual cortex (V1). We propose that this component may link sensory activity with memory activity.

Complementary Hemispheric Specialization in Monkeys IT IS IMPORTANT TO KNOW WHETHER nonhuman primates have complementary specialization of the cerebral hemispheres corresponding to the well-known differences described for human beings, in [...]

Cryopreservation, Culture, and Transplantation of Human Fetal Mesencephalic Tissue into Monkeys TRANSPLANTATION OF FETAL NEURAL tissue in rodents has been shown to alter host neurological, endocrine, cognitive, and motor functions; [...]

Primates OUR GENETIC RELATIONSHIP TO APES AND MONKEYS, THE consequence of our relatively recent common evolutionary ancestry, underlies the similar structural organizational development, and functioning of humans and primates. The [...]

Somatosensory nerve fibers have generally been assumed to have no chemical or electrical synapses with one another outside the central nervous system. However, cross talk between nerve fibers, presumably due [...]

Aldolase Activity of a Plasmodium falciparum Protein with Protective Properties IMMUNIZATION OF MONKEYS WITH IRRADIATED merozoites and schizonts of the human malaria parasite Plasmodium falciparum induces a marked degree of [...]

The capacity for adaptive regulation or 'motor learning' plays an important role in establishing and maintaining the excellent performance of the adult vestibulo-ocular reflex (VOR). In normal individuals, the VOR [...]

Task-Relevant Late Positive Component of the Auditory Event-Related Potential in Monkeys Resembles P300 in Humans The event-related brain potential (ERP) in humans, which is evoked by a task-relevant, rare stimulus, [...]

Many different infectious agents have been isolated from patients with acquired immunodeficiency syndrome (AIDS), but none of these has been clearly implicated as the cause of this disease. The difficulty [...]

AIDS vaccine research has been through tough times lately, with negative results overshadowing the positive ones. Yet in this gloom, there has been one shining light: the success, in monkey [...]

New data from macaques confiscated from a Silver Spring researcher a decade ago challenge neuroscience dogma Experiments that are among the most controversial ever performed on research animals have yielded [...]

Twenty-five percent of the American population is estimated to be nearsighted, and no one knows why. In fact, until recently, there were no good ways to study myopia. The investigations [...]

The amygdaloid complex has long been considered essential for the sensory arousal of affective responses, that is, for the association of sensory stimuli with emotions (1, 2). We now report [...]

Discovery of naturally acquired leprosy in a sooty mangabey monkey (Cercocebus atys) (1, 2) has prompted us to reevaluate the susceptibility of nonhuman primates to the disease. The nine-banded armadillo [...]
