Psycho-Social Effects Of A Brain-Training Program Among Healthy Older Adults, Desma Hurley, M. Jean Turner, William C. Bailey

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Grounded in cognitive neuroscience and social exchange theory, this research evaluated the relationship between changes in cognitive functioning and two psycho-social dimensions of life among healthy adults over the age of 70 (N=12). Specific psycho-social dimensions examined were social interaction and depression. Six females and six males participated in the study. All were white, college-educated individuals residing in a life-care residential retirement community. The participants used the Posit Science® Brain Fitness Program™, an auditory-based computer training program that improves memory and speed of processing, for forty hours over an eight-week period. Pre- and post-tests related to social interaction and depressive …

Trends. Terrorist Brains, Ibpp Editor

International Bulletin of Political Psychology

This Trends article discusses the construct of biological reductionism in the context of the case of Red Army Faction member Ulrike Meinhof. For the author, overly emphasizing the biological aspects of Ms. Meinhof’s case might obscure legitimate grievances, and ultimately, lead to more cases of violence associated with terrorism.

Method To Correct The Voxel Size In Press Localized Nmr Stereoscopy, Diana M. Lindquist, Roger M. Hawk, Richard A. Komoroski

Journal of the Arkansas Academy of Science

Two techniques commonly used on human magnetic resonance spectroscopy systems to obtain spectra from localized volumes in the brain are point resolved spectroscopy (PRESS) and stimulated echo acquisition mode (STEAM) spectroscopy. PRESS gives a signal twice as large as that obtained with STEAM, but suffers from longer minimum echo times. While STEAM must be used to detect species with short spin-spin relaxation times, PRESS can be used for species with longer relaxation times to give a spectrum with a better signal to noise ratio. Only STEAM was provided for the GE Omega 4.7 T small animal imager used in this …

Interview: Brenda Laurel, Jason Challas

SWITCH

This interview with Brenda Laurel, Virtual Reality (VR) author and thinker, discusses the applications and challenges of VR. Creating an emphatic experience using VR technology is possible, but the challenge lies in designing an environment that models the senses to stimulate emotions. VR enables experiences of different genders, but physiological differences between the sexes exist and are important to understand. However, technology used to create the environment and simulation of physical objects in VR is only in the developmental stage. Laurel believes in the importance of keeping the mind grounded in the physical body, in order to strengthen the appreciation …

Multisite Microprobes For Electrochemical Recordings In Biological Dynamics, G. Sreenivas, S. S. Ang, R. M. Ranade, A. S. Salian, W. D. Brown

Journal of the Arkansas Academy of Science

For over 30 years, techniques have been developed that allow for the microscale (10-30 /mum) measurement of chemical signals with high temporal resolution (1-200 Hz). Such measurements, called in vivo electrochemical recordings, allow for the direct determination of neurotransmitter molecules and related compounds in biological systems. Multiple recordings, simultaneously performed at different, closely spaced, well defined locations throughout a three-dimensional tissue volume in the brain, are of interest in neuroscience. Developments in microelectronic techniques enable the fabrication of multi-electrode microprobes for recording extracellular action potentials generated by individual neurons simultaneously. A high-yield microfabrication process has been successfully developed for the …

Chemical Poisoning In Animals. 2. Lead, H D. Seddon

Journal of the Department of Agriculture, Western Australia, Series 4

LEAD is the most frequent cause of poisoning in farm animals, especially of cattle.

All animals and man are susceptible to large doses, but small repeated doses may accumulate to toxic proportions in the body.

Cattle and sheep are more susceptible to poisoning and are more likely to have access to sources of lead.
