  Partial volume correction for PET quantification and its impact on brain network in Alzheimer's disease 

  Yang, Jiarui; Hu, Chenhui; Guo, Ning; Dutta, Joyita; Vaina, Lucia M.; Johnson, Keith A.; Sepulcre, Jorge; El Fakhri, Georges; Li, Quanzheng (Nature Publishing Group, 2017-10-12)

  Amyloid positron emission tomography (PET) imaging is a valuable tool for research and diagnosis in Alzheimer’s disease (AD). Partial volume effects caused by the limited spatial resolution of PET scanners degrades the ...

  The emotional valence of subliminal priming effects perception of facial expressions 

  Huang, Melissa A.; Rana, Kunjan D.; Vaina, Lucia M. (2016)

  We investigated, in young healthy subjects, how the affective content of subliminally presented priming images and their specific visual attributes impacted conscious perception of facial expressions. The priming images ...

  Improving the nulling beamformer using subspace suppression 

  Vaina, Lucia M.; Rana, Kunjan; Hämäläinen, Matti (Frontiers Media, 2018-04-29)

  Magnetoencephalography (MEG) captures the magnetic fields generated by neuronal current sources with sensors outside the head. In MEG analysis these current sources are estimated from the measured data to identify the ...

  Functional neuroanatomy of time-to-passage perception 

  Geng, Yansong; Sikoglu, Elif M.; Hecht, Heiko; Vaina, Lucia M. (Scientific Research Publishing, 2018)

  The time until an approaching object passes the observer is referred to as time-to-passage (TTP). Accurate judgment of TTP is critical for visually guided navigation, such as when walking, riding a bicycle, or driving a ...

  A paperfluidic platform to detect Neisseria gonorrhoeae in clinical samples 

  Horst, Audrey L.; Rosenbohm, Justin M.; Kolluri, Nikunja; Hardick, Justin; Gaydos, Charlotte A.; Cabodi, Mario; Klapperich, Catherine M.; Linnes, Jacqueline C. (Springer, 2018-04-11)

  Globally, the microbe Neisseria gonorrhoeae (NG) causes 106 million newly documented sexually transmitted infections each year. Once appropriately diagnosed, NG infections can be readily treated with antibiotics, but ...

  Cortical gamma rhythms modulate NMDAR-mediated spike timing dependent plasticity in a biophysical model 

  Lee, Shane; Sen, Kamal; Kopell, Nancy (Public Library of Science, 2009-12-01)

  Spike timing dependent plasticity (STDP) has been observed experimentally in vitro and is a widely studied neural algorithm for synaptic modification. While the functional role of STDP has been investigated extensively, ...

  Representation of time-varying stimuli by a network exhibiting oscillations on a faster time scale 

  Shamir, Maoz; Ghitza, Oded; Epstein, Steven; Kopell, Nancy (Public Library of Science, 2009-05-01)

  Sensory processing is associated with gamma frequency oscillations (30–80 Hz) in sensory cortices. This raises the question whether gamma oscillations can be directly involved in the representation of time-varying stimuli, ...

  Automating functional enzyme screening & characterization 

  Ortiz, Luis; Lashkaripour, Ali; Densmore, Douglas (International Workshop on Bio-Design Automation (IWBDA), 2018-08-03)

  Microfluidics continue to gain traction as an inexpensive alternative to standard multi-well plate-based, and flow cytometry- based, assay platforms. These devices are especially useful for the types of ultra-high throughput ...
