Neuroanatomical structure appears to be altered in preterm infants, but there has been little insight into the major perinatal risk factors associated with regional cerebral structural alterations. MR images were taken to quantitatively compare regional brain tissue volumes between term and preterm infants and to investigate associations between…

Fifteen years ago, Pascual-Leone and colleagues used transcranial magnetic stimulation (TMS) to investigate speech production in pre-surgical epilepsy patients and in doing so, introduced a novel tool into language research. TMS can be used to non-invasively stimulate a specific cortical region and transiently disrupt information processing. These…

Two studies used event-related potentials (ERPs) to examine neural manifestations of emotion recognition in 7-month-old infants. In the first study, 20 infants were presented with 2 alternating achromatic slides of the same female model posing a happy and a fearful expression. Infants' ERPs revealed a prominent positive component to the happy face…

This literature review provides support for the idea that subtle anatomical and functional deviations in the brain correlate with specific types of reading disorders. It finds evidence that symmetry or reversed asymmetry in the plana temporale may be associated with difficulty in acquiring sound/symbol relationships. Studies are reported to show…

Two experiments were conducted to determine a possible relationship between the right hemisphere, music perception, and mental imagery. The first experiment compared two groups of college students, one of which showed a preference for left hemisphere thinking (n=22) and the other a preference for right hemisphere thinking (n=20), in order to test…

Article investigated the possible effects of drug abuse upon the central nervous system by comparing the incidence of EEG abnormality in drug abusers and non-users. (Author/RK)

Summarizes research done on the resting and action potential of nerve impulses, electrical excitation of nerve cells, electrical properties of Nitella, and temperature effects on action potential. (GS)

Longitudinal studies of mother-child interactions for the third trimester of pregnancy to age 4 are described. The effort is aimed at analyzing early childhood data to determine stability of mother-infant interaction, correlations among mothers' character as defined by adaptive and maladaptive defenses, major conflicts, sense of reality, and…

The manual describes procedures involved in administering and scoring a neurodevelopmental examination of children from birth to 2 years of age. The test is designed to be easily incorporated into routine health programs. The instrument is easily learned, quickly administered, objectively based, and capable of producing early evidence of…

A model for incorporating selected nursing practitioner skills at the University of Rochester School of Nursing (New York) begins the teaching of physical assessment skills with the neurological examination in the first year of the undergraduate nursing major. (EA)
