A major shift is happening within neurophysiology: a population doctrine is drawing level with the single-neuron doctrine that has long dominated the field. Population-level ideas …
Recent work has sought to understand the behavior of neural networks by comparing representations between layers and between different trained models. We examine methods …
The analysis of neural dynamics in several brain cortices has consistently uncovered low- dimensional manifolds that capture a significant fraction of neural variability. These neural …
Although the generation of movements is a fundamental function of the nervous system, the underlying neural principles remain unclear. As flexor and extensor muscle activities …
Highlights•New generations of recording and computing technologies have enabled neuroscience at the level of the neural population.•Landmark scientific findings suggest the …
Most brain functions involve interactions among multiple, distinct areas or nuclei. For instance, visual processing in primates requires the appropriate relaying of signals across …
Populations of cortical neurons flexibly perform different functions; for the primary motor cortex (M1) this means a rich repertoire of motor behaviors. We investigate the flexibility of …
Primate motor cortex projects to spinal interneurons and motoneurons, suggesting that motor cortex activity may be dominated by muscle-like commands. Observations during …
Neural activity is often described in terms of population-level factors extracted from the responses of many neurons. Factors provide a lower-dimensional description with the aim of …
