“…These links include not only frontal motor areas, but also language-related areas such as Broca's region (Desmond et al, 2005;Mariën et al, 2001). As highlighted by Murdoch (2010), "this reciprocal connectivity forms a series of segregated neural loops that are hypothesized to facilitate linguistic function in the same way that the cerebellum enhances motor functions (Leiner et al, 1989). "…”

Some language processing theories propose that, just as for other somatic actions, self-monitoring of language production is achieved through internal modeling. The cerebellum is the proposed center of such internal modeling in motor control, and the right cerebellum has been linked to an increasing number of language functions, including predictive processing during comprehension.Relating these findings, we tested whether the right posterior cerebellum has a causal role for self-monitoring of speech errors. Participants received 1Hz repetitive transcranial magnetic stimulation during 15 minutes to lobules Crus I and II in the right hemisphere, and, in counterbalanced orders, to the contralateral area in the left cerebellar hemisphere (control) in order to induce a temporary inactivation of one of these zones. Immediately afterwards, they engaged in a speech production task priming the production of speech errors.Language production was impaired after right compared to left hemisphere stimulation, a finding that provides evidence for a causal role of the cerebellum during language production. We interpreted this role in terms of internal modeling of upcoming speech through a verbal working memory process used to prevent errors.

“…However, as Leiner, Leiner & Dow (1989) note, the human cerebellum (in particular, the lateral cerebellar hemispheres and ventrolateral cerebellar dentate nucleus) has evolved enormously, becoming linked not only with the frontal motor areas, but also some areas further forward in the frontal cortex, including Broca's language area. (Leiner et al, 1989; 1991; Leiner, Leiner & Dow, 1993) concluded that the cerebellum is therefore central for the acquisition of 'language dexterity'. In effect, then, they proposed that the cerebellum is critically involved in the automatisation of any skill, whether motor or cognitive.…”

“…There is an information-processing system relating to movement and cognitive actions, such as planning, reasoning, and emotion (Leiner et al, 1989). The cerebellum, known to be involved only in voluntary and involuntary motor control, also plays a major role in thought itself (Leiner et al, 1986); the resulting information-processing system may be essential for the manipulation of kinesthetic mind.…”

This study presents a new theory to explain the neural origins of human mind. This is the psychomotor theory. The author briefly analyzed the historical development of the mind-brain theories. The close relations between psychological and motor systems were subjected to a rather detailed analysis, using psychiatric and neurological examples. The feedback circuits between mind, brain, and body were shown to occur within the mind-brain-body triad, in normal states, and psycho-neural diseases. It was stated that psychiatric signs and symptoms are coupled with motor disturbances; neurological diseases are coupled with psychological disturbances; changes in cortico-spinal motor-system activity may influence mind-brain-body triad, and vice versa. Accordingly, a psychomotor theory was created to explain the psychomotor coupling in health and disease, stating that, not the mind-brain duality or unity, but the mind-brain-body triad as a functional unit may be essential in health and disease, because mind does not end in the brain, but further controls movements, in a reciprocal manner; mental and motor events share the same neural substrate, cortical, and spinal motoneurons; mental events emerging from the motoneuronal system expressed by the human language may be closely coupled with the unity of the mind-brain-body triad. So, the psychomotor theory rejects the mind-brain duality and instead advances the unity of the psychomotor system, which will have important consequences in understanding and improving the human mind, brain, and body in health and disease.
