37. Temporal dynamics of verbal object comprehension
Knowledge of the stage composition and the temporal dynamics of human cognitive operations is critical for building theories of higher mental activity. This information has been difficult to acquire, even with different combinations of techniques such as refined behavioral testing, electrical recording/interference, and metabolic imaging studies. Verbal obje

38. Swing it to the left, swing it to the right: enacting flexible spatial language using a neurodynamic framework
Research is continually expanding the empirical and theoretical picture of embodiment and dynamics in language. To date, however, a formalized neural dynamic framework for embodied linguistic processes has yet to emerge. To advance embodied theories of language, the present work develops a formalized neural dynamic framework of spatial language that explicit

39. A post-tetanic time window for the reinforcement of long-term potentiation by appetitive and aversive stimuli
Current theories on the encoding and storage of information in the brain commonly suppose that a short-term memory is converted into a lasting one; thus, it becomes consolidated over time. Within a finite period after training, such a short-term memory can be reinforced by behavioral and humoral stimuli. We have found that, long-term potentiation (LTP), a li

40. Characterizing the use of health care services delivered via computer networks.
OBJECTIVE: Evaluators must develop methods to characterize the use of the rapidly proliferating electronic networks that link patients with health services. In this article the 4-S framework is proposed for characterizing the use of health services delivered via computer networks. The utility of the 4-S framework is illustrated using data derived from a comp

41. Fractionating the neural substrate of cognitive control processes
Psychological and neurobiological theories of cognitive control must account for flexible, seemless transitions among cognitive operations. When subjects switch between tasks, they must both inhibit the previous task and re-engage in a different task. Inhibition of the disengaged task remains active for a period of time and has to be overcome when re-engagin

42. A neomorphic syntaxin mutation blocks volatile-anesthetic action in Caenorhabditis elegans
The molecular mechanisms underlying general anesthesia are unknown. For volatile general anesthetics (VAs), indirect evidence for both lipid and protein targets has been found. However, no in vivo data have implicated clearly any particular lipid or protein in the control of sensitivity to clinical concentrations of VAs. Genetics provides one approach toward

43. Changes in Performance Monitoring During Sensorimotor Adaptation
Error detection and correction are essential components of motor skill learning. These processes have been well characterized in cognitive psychology using electroencephalography (EEG) to record an event-related potential (ERP) called error-related negativity (ERN). However, it is unclear whether this ERP component is sensitive to the magnitude of the error
