Demixed principal component analysis of neural population data

D Kobak, W Brendel, C Constantinidis, CE Feierstein… - elife, 2016 - elifesciences.org
Neurons in higher cortical areas, such as the prefrontal cortex, are often tuned to a variety of
sensory and motor variables, and are therefore said to display mixed selectivity. This …
