Historically, psychologists and neuroscientists have distinguished between processes supporting memory for events across retention delays of several seconds (short-term memory, STM), and those supporting memory for events across longer retention delays of minutes or more (long-term memory, LTM). Dissociations reported in some neuropsychological studies have contributed to a popular view that th...

What comes to mind when I hear the name Karen Zander: case manager pioneer, brilliant and compassionate nurse leader, articulate teacher, mentor, and friend. Karen has a unique perspective on health care today as a consumer and provider. While she manages through physical limitations, it has never diminished her passion, commitment or can-do spirit. Her contributions to the case management prac...

The treatment of schizophrenia for the last half century has been with dopamine (DA) D(2) receptor blockers, implicating a hyperdopamine basis for psychosis. However, a 2007 report found that the glutamate agonist LY404039 was effective in schizophrenia, suggesting a hypoglutamate state for the illness. Although phencyclidine psychosis also supports a hypoglutamate cause, assessing the basic an...

Two patterns from large-scale DNA sequence data have been put forward as evidence that speciation between humans and chimpanzees was complex, involving hybridization and strong selection. First, divergence between humans and chimpanzees varies considerably across the autosomes. Second, divergence between humans and chimpanzees (but not gorillas) is markedly lower on the X chromosome. Here, we d...

The World Medical Association's Declaration of Helsinki offers guidelines to doctors engaged in biomedical research with human subjects. The fundamental distinction of the Declaration is between clinical research combined with professional care and non-clinical scientific research. If hospital patients are the experimental subjects, then the former research must be carried out by the patient's ...

An inner retinal microcircuit composed of dopamine (DA)-containing amacrine cells and melanopsin-containing, intrinsically photosensitive retinal ganglion cells (M1 ipRGCs) process information about the duration and intensity of light exposures, mediating light adaptation, circadian entrainment, pupillary reflexes, and other aspects of non-image-forming vision. The neural interaction is recipro...
