DESCRIPTION:This week we will discuss and debate a very recent paper by Kw
 ak and Curtis\, published in Neuron (2022).\n\nAbstract: “Working memory
  (WM) enables information storage for future use\, bridging the gap betwee
 n perception and behavior. We hypothesize that WM representations are abst
 ractions of low-level perceptual features. However\, the neural nature of 
 these putative abstract representations has thus far remained impenetrable
 . Here\, we demonstrate that distinct visual stimuli (oriented gratings an
 d moving dots) are flexibly recoded into the same WM format in visual and 
 parietal cortices when that representation is useful for memory-guided beh
 avior. Specifically\, the behaviorally relevant features of the stimuli (o
 rientation and direction) were extracted and recoded into a shared mnemoni
 c format that takes the form of an abstract line-like pattern. We conclude
  that mnemonic representations are abstractions of percepts that are more 
 efficient than and proximal to the behaviors they guide” (Kwak & Curtis\
 , 2022).\n\nReference: Kwak\, Y.\, & Curtis\, C. E. (2022). Unveiling the
