What Is Population Coding? What Evidence Is There for It

Question

Examlex · Accepted Answer

The Answer is Population coding is a concept in neuroscience that suggests that information is represented in the brain by the combined activity of a population of neurons, rather than by the activity of individual neurons. This means that a particular stimulus or action is encoded by the pattern of activity across a group of neurons, with each neuron contributing a small part to the overall representation.

In the context of motor control, there is evidence for population coding from studies that have examined the activity of neurons in the motor cortex during movement. For example, researchers have found that individual neurons in the motor cortex are not specific to particular movements, but instead contribute to the representation of multiple movements. This suggests that the specific movement being performed is encoded by the combined activity of a population of neurons, with each neuron contributing to the overall representation of the movement.

Additionally, studies have shown that the activity of a population of neurons in the motor cortex can predict the direction and force of upcoming movements, further supporting the idea of population coding in motor control. Overall, the evidence from motor control research suggests that population coding is an important mechanism for representing and controlling movements in the brain.
