Fig. 3: Reconstructed phase space of depth cortical recordings reveals a low dimensional attractor for patients with thalamic injury.

a We reconstructed the phase space of recordings obtained from depth PFC recording for all the patients. Patients 4 and 5 with unilateral and bilateral thalamic injury, respectively, show a structured phase space that repeatedly visits similar trajectories reflecting a limited number of available states in the repertoire of cortical networks. b Phase space of 20 s of cortical recordings consisted of a ten-second baseline (gray) followed by a ten-second train of single pulses of stimulation (red). The timing of single pulses is shown in red on the recorded LFP. Responses are consistent with a ring attractor in patients 4 and 5.
