Increased functional dynamics in civil aviation pilots: Evidence from a neuroimaging study

Civil aviation is a distinctive career. Pilots need to monitor the entire system in real time. However, the psychophysiological mechanism of flying is largely unknown. The human brain is a large-scale interconnected organization, and many stable intrinsic large-scale brain networks have been identified. Among them are three core neurocognitive networks: default mode network (DMN), central executive network (CEN), and salience network (SN). These three networks play a critical role in human cognition. This study aims to examine the dynamic properties of the three large-scale brain networks in civil aviation pilots. We collected resting-state functional magnetic resonance imaging data from pilots. Independent component analysis, which is a data-driven approach, was combined with sliding window dynamic functional connectivity analysis to detect the dynamic properties of large-scale brain networks. Our results revealed that pilots exhibit an increased interaction of the CEN with the DMN and the SN along with a decreased interaction within the CEN. In addition, the temporal properties of functional dynamics (number of transitions) increased in pilots compared to healthy controls. In general, pilots exhibited increased between-network functional connectivity, decreased within-network functional connectivity, and a higher number of transitions. These findings suggest that pilots might have better functional dynamics and cognitive flexibility.

“…These various problems, although well defined, currently have no practical solution. Helmet display and optical design have become an integral part of aircraft design in recent years (Jenkins & Gallimore, 2008). Our approach involved (+) Add reading glasses, +1.5 to +3.0 diopters, to be used during long hours of college study to lessen focusing effort (Cheng et al, 2011).…”

Experimental design phase of a pilot study at Annapolis is described, using reading glasses, +1.5 D. to +3.0 D. to alleviate college myopia. College students often become 1.0 to 2.0 diopters more myopic, so reading glasses were explored to partially cancel the effects of the study environment. N = 25 different sets of (+)Add lenses are evaluated, for required adjustment period and reading comfort. Three computer models are developed to predict refraction versus time. Basic control system equations predict exponential myopia shift of refractive state R(t) with time constant t0 = 100 days. Linear, exponential and Gompertz computer results are compared calculating refraction R(t) during the college years, showing correlation coefficients |r| = 0.96 to 0.97, accurate +/−0.31 D. over a 14 year interval. Typical college myopia rate is −0.3 to −0.4 D/yr. Reading glasses may be a simple, practical solution to stabilize college myopia.

“…Head mounted displays (HMDs) are being explored as an alternative means of displaying relevant information which has been traditionally been done on a tablet type display mounted on the user's chest. Numerous studies have investigated the application of HMDs in aviation (Jenkins & Gallimore, 2008;Morphew, Shively, & Casey, 2004;Rolland & Hua, 2005), military (Ferrin, 1999;Livingston et al, 2002), driving (He et al, 2015;Sawyer, Finomore, Calvo, & Hancock, 2014), firefighting (Wilson et al, 2005), and medical (Rolland & Fuchs, 2000;Sanderson et al, 2008) applications. Results indicate that HMDs may enhance situation awareness (see Endsley, 2011), improve performance (He et al, 2015;Tippey et al, 2014), and provide more intuitive and natural interactions with a synthetic environment (Santos et al, 2009) compared to more traditional displays especially for dismounted operators who must wear all of their gear.…”

Head mounted displays (HMDs) are being explored as an alternative means of displaying relevant information to dismounted operators. The goal of this project was to examine different visual display concepts and evaluate participant’s attention allocation to information presented on their HMD. Additionally, their ability to detect potential threats in the environment was also evaluated. This information will help revamp the design of information displays for HMDs. The task in this study required participants to monitor their HMD for critical alerts and respond accordingly while also making shoot/no shoot decisions to threats in their environment. We hypothesized that as information is presented in different layouts on the HMD, it will reduce the participants’ ability to detect real world events. Accuracy of the shoot/no shoot decisions was collected along with accuracy of detection of information on the HMD. We found that shooting performance was not affected between the three HMD layouts however information detected on the HMD was worst when all information was in the center of the HMD. The data from this study will be used to help develop intelligent visual displays used by Battlefield Airmen to accomplish their mission.
