Article Figures & Tables
Figures
- Fig. 1
Interhemispheric signal propagation (ISP) per cortical area in psychopathic offenders and healthy controls. DLPFC = dorsolateral prefrontal cortex.
- Fig. 2
Psychopathic offenders demonstrate an increase in cortical silent period (CSP) in the right motor cortex.
- Fig. 3
The mean amplitude of the cortical evoked potentials is represented at different times (successive lines) in healthy controls (left 2 columns) and psychopathic offenders (right 2 columns). The mean amplitude is colour coded. DLPFC = dorsolateral prefrontal cortex; TMS = transcranial magnetic stimulation.
- Fig. 4
Temporal representation of the activity of the prefrontal electrodes, thought to measure dorsolateral prefrontal cortex activity. ISP = inter-hemispheric signal propagation; TMS = transcranial magnetic stimulation.
