Parietal reach region
The parietal reach region (PRR) is a region within the posterior parietal cortex of the human brain that is stimulated through reaching for an object. The PRR was initially proposed by Andersen and Buneo,[1] but they just generally explored the idea as postural modulations. Dr. Steven Chang went further in depth by showing the receptive fields of PRR neurons are multiplicatively stimulated through the combination of initial gaze position and initial hand position.[2] This multiplicative stimulation is known as gain-field encoding. The parietal reach region uses gain-field encoding to calculate the amount of hand displacement needed to reach for an object.
