What is population vector?

Population vector refers to the collective behavior of a group of neurons that encode information about a feature of the outside world or an action the animal plans to take. It is expressed as the activity of a set of neurons that collectively represent a particular stimulus or action. The population vector is a representation of the direction and magnitude of the neural activity in response to a stimulus or action. It can be used to decode the intentions or perceptions of an animal by analyzing the pattern of neural activity. The population vector is frequently used in neuroscience research to study the neural coding of sensory information and motor planning.
