Attentional capture by emotional stimuli is preserved in patients with amygdala lesions.

The importance of cues signaling reward, threat or danger would suggest that they receive processing privileges in the neural systems underlying perception and attention. Previous research has documented enhanced processing of motivationally salient cues, and has pointed to the amygdala as a candidate neural structure underlying the enhancements. In the current study, we examined whether the amygdala was necessary for this emotional modulation of attention to occur.

Reprint of: Fear-enhanced visual search persists after amygdala lesions.

Previous research has indicated that the amygdala is a critical neural substrate of the emotional modulation of attention. However, a recent case study suggests that the amygdala may not be essential for all types of emotion-attention interactions. In order to test this hypothesis, we assessed the visual-search performance of patients with unilateral amygdala lesions, matched controls, and medication-matched epilepsy patients with intact amygdalae.

The impact of airborne dust on respiratory health in children living in the Aral Sea region.

Background: Anecdotally, people living in the Aral Sea region report an increase in the prevalence of respiratory illnesses, particularly in children, and there is widespread belief that this is due to dust from the Aral Sea bed.

Methods: We conducted a survey of respiratory symptoms and lung function in children aged 7-10 years living in 18 communities in 6 geographical regions in the Aral Sea area. We monitored dust deposition rates monthly for the duration of the study.

Provision of health care in rural Afghanistan: needs and challenges.

Afghanistan's health system is severely limited in terms of preventive and curative services, referral systems, and human resources. Most of the country's citizens reside in rural areas, a majority of which are served by "basic health units" (small and simple facilities that provide primary care), and these rural residents face additional challenges regarding timely access to quality health care. The analysis described in this article, which focuses on data derived from 2 rural health units during a 1-year period, revealed that infectious diseases, mainly acute respiratory infections, were a primary concern and that there is a clear need for increasing access to health services.

The Aral Sea disaster and self-rated health.

This study examined the effect of psychosocial factors and environmental perceptions on self-rated health in the environmentally devastated Aral Sea area of Karakalpakstan. Self-rated health was assessed using a questionnaire on 881 randomly selected individuals from three communities. Communities were chosen based on relative differences with regards to economic and ethnic characteristics, and distance from the sea coast.

Safe water for the Aral Sea Area: could it get any worse?

The environmental adversities around the Aral Sea in Central Asia have been the subject of recent research. Attempts at sustainable provision of palatable drinking water in low chemical and microbial contaminants for the 4 million people in the two countries around the Aral littoral have been largely unsuccessful. In the last few years, severe drought has further depleted the amount of available water.

Impacts of an environmental disaster on psychosocial health and well-being in Karakalpakstan.

The people of Karakalpakstan, along with those of the entire Aral Sea region, are facing a multitude of health problems corresponding to the drying of the Aral Sea and accompanying ecological consequences. In case studies of other environmental disasters, research has shown that environmental exposures may impact not only the physiological but also the psychosocial health of individuals. This research aims to determine the contribution of the environmental disaster to the psychosocial health of people living in Karakalpakstan, a semi-autonomous Republic in Uzbekistan.
