Echopraxia in schizophrenia: possible mechanisms.
The aim of the current study was to present a possible mechanism underpinning echopraxia in schizophrenia. It is proposed that echopraxia occurs in schizophrenia when the mirror neuron system provides a representation to the inferior frontal gyrus (IFG) and the motor cortex (and via the IFG, to the anterior cingulate cortex) and that this potential becomes executed movement, when the disorder is associated with decreased inhibition and increased arousal.
