Oscillations and aperiodic activity: Evidence for dynamic changes in both during memory encoding

Posted by klaurent UCSD / Salk

Kavli Affiliate: Bradley Voytek | Authors: Michael Preston, Natalie Schaworonkow and Bradley Voytek | Summary: Abstract Electrical recordings of human brain activity via electroencephalography (EEG) show prominent, rhythmic voltage fluctuations. These periodic oscillations have been linked to nearly every cognitive and perceptual process, as well numerous disease states. Recent methodological and theoretical advances, however, have […]

Neural representational geometry correlates with behavioral differences between monkeys

Posted by klaurent Columbia

Kavli Affiliate: Stefano Fusi | Authors: Valeria Fascianelli, Fabio Stefanini, Satoshi Tsujimoto, Aldo Genovesio and Stefano Fusi | Summary: Abstract Animals likely use a variety of strategies to solve laboratory tasks. Traditionally, combined analysis of behavioral and neural recording data across subjects employing different strategies may obscure important signals and give confusing results. Hence it […]

VLBA reveals the absence of a compact radio core in the radio intermediate quasar J2242+0334 at z =5.9

Posted by klaurent Peking

Kavli Affiliate: Ran Wang | First 5 Authors: Yuanqi Liu, Ran Wang, Emmanuel Momjian, Yingkang Zhang, Tao An | Summary: High-resolution imaging is crucial for exploring the origin and mechanism of radio emission in quasars, especially at high redshifts. We present 1.5 GHz Very Long Baseline Array (VLBA) images of the radio continuum emission from […]

What does an interferometer really measure? Including instrument and data characteristics in the reconstruction of the 21cm power spectrum

Posted by klaurent MIT

Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Adélie Gorce, Samskruthi Ganjam, Adrian Liu, Steven G. Murray, Zara Abdurashidova | Summary: Combining the visibilities measured by an interferometer to form a cosmological power spectrum is a complicated process in which the window functions play a crucial role. In a delay-based analysis, the mapping between […]

A neural model of proximity to reward

Posted by klaurent Columbia

Kavli Affiliate: Costa, Rui | Authors: Paul Botros, Nuria Vendrell-Llopis, Rui Costa and Jose Carmena | Summary: Abstract Throughout learning, refinement of cortical activity in cortex, a process termed “credit assignment”, underlies the refinement of behavioral actions leading to reward. While previous research shows striatum’s role in linking behavior to reward, striatum’s role in linking […]
