DESCRIPTION:This week we will discuss and debate a recent paper by So and 
 Shadlen\, published in Neuron (2022).\n\nAbstract: “Neurons in the later
 al intraparietal cortex represent the formation of a decision when it is l
 inked to a specific\naction\, such as an eye movement to a choice target. 
 However\, these neurons should be unable to represent a\ndecision that tra
 nspires across actions that would disrupt this linkage. We investigated th
 is limitation by\nsimultaneously recording many neurons from two rhesus mo
 nkeys. Although intervening actions disrupt\nthe representation by single 
 neurons\, the ensemble achieves continuity of the decision process by pass
 ing\ninformation from currently active neurons to neurons that will become
  active after the action. In this way\, the\nrepresentation of an evolving
  decision can be generalized across actions and transcends the frame of re
 ference that specifies the neural response fields. The finding extends pre
 vious observations of receptive field\nremapping\, thought to support the 
 stability of perception across eye movements\, to the continuity of a\ntho
 ught process\, such as a decision” (So & Shadlen\, 2022).\n\nReference:
