In adult monkeys with dorsal rhizotomies extending from the second cervical (C2) to the fifth thoracic (T5) vertebrae, cortex deprived of its normal inputs regained responsiveness to inputs conveyed by intact peripheral afferents from the face [T.P. Pons, P.E. Garraghty, A.K. Ommaya, J.H. Kaas, E. Taub, M. Mishkin, Massive reorganization of the primary(More)
It has previously been demonstrated that the central somatosensory topographic reorganization within deprived cortex that follows peripheral nerve injury in adult monkeys occurs in at least two stages: an immediate unmasking period; and a more prolonged period where deprived areas of cortex come to express new receptive fields in a topographically arranged(More)
The influence of the cerebellum on activity of the septal region, hippocampus, and amygdala of cats and rats was determined by obtaining unit recordings from those supratentorial sites with cerebellar stimulation. With stimulation of the postral vermis, fastigial nucleus, and intervening midline folia of the cerebellum, units in the septal region were(More)
We have previously shown that most of the reorganization that typically follows median nerve transection in adult squirrel monkeys is dependent on normally functioning N-methyl-D-aspartate (NMDA) receptors. Here, we have evaluated two additional hypotheses: (1) is the immediate "unmasking" found after median nerve transection NMDA receptor-dependent? and(More)
Electron microscopic study of brain tissues of monkeys chronically exposed to psychoactive Cannabis showed widening of the synaptic cleft, electron opaque material in the cleft and in pre- and postsynaptic regions, and some "clumping" of synaptic vesicles. In contrast, tissues of control monkeys showed no ultrastructural changes.
Case material is presented to illustrate the thesis that the ability to create an imaginary companion during childhood is an early expression of the special ego aptitudes found in creative individuals in adult life. Such "companions" allow these children to attempt to master creatively a variety of narcissistic mortifications suffered in reality and to(More)
In this paper, I have described certain transference fantasies found in treatments involving older patients and younger therapists. These include the defense against the loss of objects, the resurrection in fantasy of prior lost objects, the bolstering of one's sense of oneself as phallic and masculine or as more acceptably feminine, and the fantasy of(More)
The abundance pattern of s-process nuclides confirms severe mass separation in the Sun and in the parent star that gave birth to the Solar System. The most abundant elements in the interior of the Sun are Fe, Ni, O, Si and S. These five, even-Z elements with high nuclear stability comprize the bulk material of ordinary meteorites and rocky planets close to(More)
(81)—poorly understood. Although complex, a mechanistic, cellular-level explanation of S1 map plasticity appears increasingly tractable and would constitute a major step toward understanding cortical information storage. Language acquisition is one of the most fundamental human traits, and it is obviously the brain that undergoes the developmental changes.(More)
