“…Consistent with our findings, there are others reports of mild to no cognitive dysfunction in patients with cerebellar lesions (4,5,29). Others reported deficits on certain EF tests in patients compared to controls, but performances were within the normal range (30). In our study, in the overall cerebellar group with the cerebellar lesion extending to the cortex, only working memory and face emotion recognition were impaired but not the other aspects of EF nor emotion processing.…”

Objective: We investigated whether the cerebellum plays a critical or supportive role in in executive and emotion processes in adults. Many investigators now espouse the hypothesis that participants with cerebellar lesions experience executive functions and emotions (EE) disorders. But we hypothesized that these disorders would be milder if the damage is relatively limited to the cerebellum compared to damage involving the cerebellum plus additional cortical areas.Methods: We studied veterans with penetrating Traumatic Brain Injury (pTBI) participating in the Vietnam Head Injury Study (VHIS). We selected veterans with a cerebellar lesion (n = 24), a prefrontal cortex lesion (n = 20), along with healthy controls (HC) (n = 55). Tests of executive functions and emotions were analyzed as well as caregiver burden. We performed between-group null hypothesis significance testing, Bayesian hypothesis tests and correlational analyses.Results: Performance of participants with cerebellar lesions which extended to the cerebral cortex was similar to the HC on the Executive Function tests but they were significantly impaired on the Working Memory Index. No differences were found on the emotional processing tasks with one exception—the Facial Expression of Emotion-Test (FEEST). We then examined a sub-group of participants with large cerebellar lesions (>15%) but minimal lesions in the cerebral cortex (<15%). This sub-group of participants performed similarly to the HC on the Working Memory Index and on the FEEST.Conclusions: We suggest that the cerebellar cortex may not be critical for executive functions or processing emotional stimuli in adults as suggested. Instead, we find that the cerebellum has a supportive role characterized by its computing of the motor requirements when EE processing is required.

“…For instance, several areas, such as the supplementary motor cortex, basal ganglia, and cerebellum, provide computations that help in producing both speech and movement (Duffy, 1995;Fiez & Raichle, 1997;Ravizza, 2001). Indeed, a recent imaging study reported activation of the supplementary motor area during TOT retrieval attempts (Kikyo, Ohki, & Sekihara, 2001).…”

“…Other areas besides the cortex are also known to be involved in speech articulation. Clinical data of speech disorders in patients with cerebellar lesions or Parkinson's disease suggest that the cerebellum and the brain stem are engaged in the motor control of speech [6][7][8]. Ackermann et al [9] showed activation of the right superior cerebellum during recitations of the names of the months by normal subjects.…”
