    OBJECTIVES: Modafinil has recently been approved for the treatment of shift work sleep disorder, making it potentially available for shift-working emergency physicians. The authors'' objectives were to determine whether modafinil improved cognitive performance of emergency physicians following overnight shifts and to record symptoms and subjective evaluations of the effect of modafinil on the participants. METHODS: This was a randomized, double-blind, placebo-controlled crossover study that followed CONSORT guidelines. Participants were assigned to one of two study groups, with study sessions occurring at least seven weeks apart, and received either modafinil or placebo depending on their random allocation. Testing after night shifts included a coding task and an AX version of the Continuous Performance Task, both of which test cognitive function. Participants also completed visual analog scales for three subjective outcomes, and symptoms were elicited. RESULTS: Modafinil facilitated performance on long interstimulus-interval AX trials (F [1, 23] = 6.65, p = 0.1) and marginally reduced errors on AY trials in the Continuous Performance Task (F [1, 23] = 3.59, p = 0.07), suggesting facilitation of sustained attention, cognitive control, and working memory. Additionally, modafinil, compared with placebo, facilitated performance on the coding task at the first session. Subjective data from visual analog scales confirmed that modafinil increased perceived alertness during the simulated patient care sessions but worsened sleep onset when opportunities for sleep arose. CONCLUSIONS: Modafinil increased certain aspects of cognitive function and subjectively improved participants'' ability to attend post-night-shift didactic sessions but made it more difficult for participants to fall asleep when opportunities for sleep arose.

    C57BL/6 mice were exposed to 5 Gy (28)Si or (56)Fe particle radiation in order to explore the immediate or short-latency effect of exposure to high energy (HZE) particle radiation on dopaminergic modification of acoustic startle and prepulse inhibition. The radiation is representative of the type which would be encountered as galactic cosmic rays during long-duration space flight. The acoustic startle response was elicited with 120 dB white noise and prepulse inhibition of the startle response was produced with 79 dB and 86 dB stimuli presented with a 125 ms onset asynchrony. Startle reactivity was inhibited by (56)Fe radiation but not by (28)Si particles. Apomorphine (3 mg/kg) produced a general inhibition of startle reactivity while haloperidol (1 mg/kg) facilitated it. Apomorphine disrupted prepulse inhibition, but only in animals which were not exposed to radiation. Both (56)Fe and (28)Si radiation exposure attenuated the disruption of prepulse inhibition induced by apomorphine. In contrast, the facilitation of prepulse inhibition induced by haloperidol was not modified by radiation. These data are consistent with a short-latency disruption of dopaminergic systems by HZE particle radiation. We speculate that this disruption may occur as a restriction in the capacity of the dopaminergic system. PMID: 16084538

    This study investigated the ability of color and motion to elicit and maintain visual attention in a sample of children with cortical visual impairment (CVI). It found that colorful and moving objects may be used to engage children with CVI, increase their motivation to use their residual vision, and promote visual learning.
