Threat imminence modulates neural gain in attention and motor relevant brain circuits in humans
Different levels of threat imminence elicit distinct computational strategies reflecting how the organism interacts with its environment in order to guarantee survival. Thereby, parasympathetically driven orienting and inhibition of on-going behavior in post-encounter situations and defense reactions in circa-strike conditions associated with sympathetically driven action preparation are typically observed across species. Here, we show that healthy humans are characterized by markedly variable individual orienting or defense response tendencies as indexed by differential heart rate (HR) changes during the passive viewing of unpleasant pictures. Critically, these HR response tendencies predict neural gain modulations in cortical attention and preparatory motor circuits as measured by neuromagnetic steady-state visual evoked fields (ssVEFs) and induced beta-band (19–30 Hz) desynchronization, respectively. Decelerative HR orienting responses were associated with increased ssVEF power in the parietal cortex and reduced beta-band desynchronization in pre-motor and motor areas. However, accelerative HR defense response tendencies covaried with reduced ssVEF power in the parietal cortex and lower beta-band desynchronization in cortical motor circuits. These results show that neural gain in attention- and motor-relevant brain areas is modulated by HR indexed threat imminence during the passive viewing of unpleasant pictures. The observed mutual ssVEF and beta-band power modulations in attention and motor brain circuits support the idea of two prevalent response tendencies characterized by orienting and motor inhibition or reduced stimulus processing and action initiation tendencies at different perceived threat imminence levels
Inventory management.
A critical aspect of blood transfusion is the timely provision of high quality
blood products. This task remains a significant challenge for many blood services
and blood systems reflecting the difficulty of balancing the recruitment of
sufficient donors, the optimal utilization of the donor's gift, the increasing
safety related restrictions on blood donation, a growing menu of specialized
blood products and an ever-growing imperative to increase the efficiency of blood
product provision from a cost perspective. As our industry now faces questions
about our standard practices including whether or not the age of blood has a
negative impact on recipients, it is timely to take a look at our collective
inventory management practices. This International Forum represents an effort to
get a snap shot of inventory management practices around the world, and to
understand the range of different products provided for patients. In addition to
sharing current inventory management practices, this Forum is intended to foster
an exchange of ideas around where we see our field moving with respect to various
issues including specialty products, new technologies, and reducing recipient
risk from blood transfusion products
