The Universal Cerebellar Transform and Dysmetria of Thought

The notion that the cerebellum modulates thought and emotion in the same way that it modulates motor control advances the understanding of the mechanisms of cognition and opens new therapeutic opportunities in behavioral neurology and neuropsychiatry.

This chapter focuses on the behavioral neurology and neuropsychiatry of the cerebellum and emphasizes the clinically relevant manifestations for adults and children with a wide range of cerebellar disorders.

Ferdinando Rossi Lecture: the Cerebellar Cognitive Affective Syndrome-Implications and Future Directions.

A new appreciation of the cerebellum incorporation into circuits that subserve cognition and emotion enables deeper understanding and improved care of patients with cerebellar ataxias and novel Cerebellar-based approaches to therapy in neuropsychiatry.

Contribution of the Cerebellum and the Basal Ganglia to Language Production: Speech, Word Fluency, and Sentence Construction—Evidence from Pathology

It is plausible that some disorders observed when damage involves one of these structures could be remote effects of abnormal activity in the other, but in a purely clinical-neuropsychological perspective, primary and remote effects in the network are difficult to disentangle.

Cerebellar-Subcortical-Cortical Systems as Modulators of Cognitive Functions.

While it is clear that cerebellar insult in childhood affects executive function performance later in life, more work is needed to elucidate the mechanisms by which executive dysfunction occurs and its developmental course.

Disruption of Cerebellar Prediction in Verbal Working Memory

It is hypothesized that a similar predictive process can generalize to cerebellar non-motor function, and that the right cerebellum plays a predictive role that is beneficial for rapidly engaging the phonological loop in verbal working memory.

The Social Cerebellum: A Large-Scale Investigation of Functional and Structural Specificity and Connectivity.

This study leveraged large-scale multimodal neuroimaging data to elucidate the structural and functional role of the cerebellum in mentalizing and provides novel insights to the network organization of the Cerebellum, an overlooked brain structure, and mentalizing, one of humans' most essential abilities to navigate the social world.

Dysmetria and Errors in Predictions: The Role of Internal Forward Model

It is proposed that motor dysmetria observed in attacks of ataxia occurs as a result of impaired predictive computation of the internal forward model in the cerebellum.

The basal ganglia and the cerebellum in human emotion

This review will discuss the basic structure and function of the BG and cerebellum and propose an updated view of their functional role in human affective processing.

The cerebellar cognitive affective syndrome (CCAS) includes impairments in executive, visual-spatial, and linguistic abilities, with affective disturbance ranging from emotional blunting and depression, to disinhibition and psychotic features.

Cerebellum and nonmotor function.

Neuroimaging and neuropsychological data supply compelling support for the view that a closed-loop circuit represents the major architectural unit of cerebro-cerebellar interactions and provides the cerebellum with the anatomical substrate to influence the control of movement and cognition.

From movement to thought: Anatomic substrates of the cerebellar contribution to cognitive processing

These proposed rules and the general and specific hypotheses offered are testable using functional neuroimaging techniques and may thus be mutually advantageous in predicting and explaining new concepts of cerebellar function.

The cerebrocerebellar system: anatomic substrates of the cerebellar contribution to cognition and emotion

Knowing the connections between the cerebellum and brain structures known to be associated with a wide array of non-motor behaviors is critical to the further development of hypotheses, experimental approaches, and clinical questions that can advance the understanding of the contribution of the Cerebellum to cognition and to disorders of intellect and emotion.

The cerebrocerebellar system.

The neural circuitry postulated to subserve the cerebellar contribution to nonmotor processing, particularly cognitive and affective modulation, is described, and the theoretical implications of these anatomic findings are discussed.

The cerebellar cognitive affective syndrome.

A constellation of deficits is suggestive of disruption of the Cerebellar modulation of neural circuits that link prefrontal, posterior parietal, superior temporal and limbic cortices with the cerebellum, called the 'cerebellar cognitive affective syndrome'.
