Okay I ended up making this write-up waaaaaay too long, so before I get into any of the jargon, let’s take a look at the finished product:
Lidar (light detection and ranging) is a common remote sensing technique used to create high-resolution three-dimensional models of landscapes and built features. Lidar uses laser pulses to measure distances to the ground or other features. Traditionally, lidar scanners are mounted to airborne or terrestrial…
A new study suggests that electric fields may represent information held in working memory, allowing the brain to overcome “representational drift,” or the inconsistent participation of individual neurons
