Verbal and spatial functions across the menstrual cycle in healthy young women.

The effects of the menstrual cycle on cognitive functions were investigated using simple verbal and spatial tasks. Eight healthy young women with a regular, established 28-day menstrual cycle and the occurrence of ovulation on day 14 were tested four ...

Functional neuroanatomy of sustained attention in schizophrenia: contribution of parietal cortices.

Deficits in sustained attention have been frequently described in schizophrenia. The neuroanatomical basis reported previously have included altered levels of activation in cingulate and prefrontal cortex, but the contribution of further regions remains ...

Event-related potential correlates of serial-position effects during an elaborative memory test.

Twenty undergraduate students participated in an elaborative learning test to evaluate the relationship between electrical brain activity and subsequently recalled and not-recalled words. Data collected from the midline (Fz, Cz, Pz) and lateral scalp ...

Semantic distance effects on object and action naming.

Graded interference effects were tested in a naming task, in parallel for objects and actions. Participants named either object or action pictures presented in the context of other pictures (blocks) that were either semantically very similar, or somewhat ...

Capturing the insights of family caregivers: survey item generation with a coupled interview/focus group process.

The usefulness of qualitative methodologies to augment and enrich quantitative studies is often overlooked. The authors goals are to describe the qualitative process employed to generate survey items and to compare the results to those of studies that ...

Spatial attention and memory versus motor preparation: premotor cortex involvement as revealed by fMRI.

Recent studies in both monkeys and humans indicate that the dorsal premotor cortex participates in spatial attention and working memory, in addition to its well known role in movement planning and execution. One important question is whether these ...

The hippocampus, space, and viewpoints in episodic memory.

A computational model of how single neurons in and around the rat hippocampus support spatial navigation is reviewed. The extension of this model, to include the retrieval from human long-term memory of spatial scenes and the spatial context of events is ...

The virtual case report.

Reports of clinical happenings are coming under increasing suspicion because of their piecemeal nature and their problematic reliance on memory. Recent research on eyewitness testimony has raised the further concern that memory of an event can be easily ...

Oculomotor effects of delta-9-tetrahydrocannabinol in humans: implications for the functional neuroanatomy of the brain cannabinoid system.

The significance of cannabinoid signaling for human cognition and motor control is still poorly understood. Here, we have investigated acute behavioral effects of oral delta-9-tetrahydrocannabinol (THC) with oculomotor paradigms in 12 healthy human ...

The role of the parahippocampal gyrus in source memory for external and internal events.

We can discriminate between the memories of real and imagined events. In this study, the traces of the perceived external events and the imagined internal events were investigated in the established paradigm of reality monitoring using event-related ...
