Quantitative functional neuroimaging of cerebral physiology in healthy aging
Functional MRI (fMRI) studies using the BOLD signal are done under the general assumption that the BOLD signal can be used as a direct index of neuronal activation. Studies of cognitive aging often compare BOLD signal amplitude and extent directly between younger and older groups, with the additional assumption that the relationship between neuronal activity and the hemodynamic response is unch...
متن کاملMemory abilities during normal aging.
One hundred and five normal subjects from 20 to 89 years old, and with a minimum of six years of formal education were selected. Subjects were divided into seven age ranges, with 15 subjects in each group. The following tests were individually administered: (1) Wechsler Memory Scale (WMS) (Wechsler, 1945); (2) Serial Verbal Learning (Ardila, Rosselli & Puente, 1994; Ardila & Ostrosky, 1991); (3...
متن کاملRelationship between Emotional Intelligence and General Health among Delinquents and Normal Juveniles
The present study investigated the relationship between emotional intelligence and the general health among delinquents and normal juveniles in Iran. The design of this study was ex-post facto design. Using a random stratified sampling technique from five districts of Iran, west, East, Norrth, South and the center: 339 juveniles (161 normal and 178 delinquent juveniles) were selected from it. A...
متن کاملStructural changes that occur during normal aging of primate cerebral hemispheres.
Human and non-human primates show cognitive decline during normal aging. Originally, the decline was attributed to a loss of cortical neurons, but recent studies have shown there is no significant cortical neuronal loss with age. Neurons acquire pigment, but the only other obvious changes are in layer 1 of neocortex. Layer 1 becomes thinner as apical tufts of pyramidal cells lose branches, as w...
متن کاملRelationship between blood pressure and cerebral blood flow during supine cycling: influence of aging.
The cerebral pressure-flow relationship can be quantified as a high-pass filter, where slow oscillations are buffered (<0.20 Hz) and faster oscillations are passed through relatively unimpeded. During moderate intensity exercise, previous studies have reported paradoxical transfer function analysis (TFA) findings (altered phase or intact gain). This study aimed to determine whether these previo...
