Fig. 4: Spatial patterns of control-related activity in a delay-match-to-sample task.
From: Working memory control dynamics follow principles of spatial computing
a Left: Schematic depiction of the delayed match-to-sample task. Right: schematic depiction of the recording locations of the four chronically implanted Utah arrays (left and right dlPFC, left and right vlPFC). b Left: the first (top) and second (bottom) task-general dPCA components of gamma activity projected using the five-session average dPCA weight vectors for each one of the five sessions. Right: plotted are the five-session averages of the first and second task-general dPCA gamma components using i) the five-session average dPCA weight vectors (black) and ii) session-specific weight vectors (red). c The 4-array spatial distribution of the session-average normalized dPCA weights used in 'b' for the first (top) and second (bottom) task dependent dPCA components. It demonstrates that the different components formed unique and stable spatial patterns distributed over PFC. Source data are provided as Source Data file.
