Demixed principal component analysis of neural population data
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 …

The largest response component in the motor cortex reflects movement timing but not movement type
Neural activity in monkey motor cortex (M1) and dorsal premotor cortex (PMd) can reflect a
chosen movement well before that movement begins. The pattern of neural activity then …
