Abstract
Objectives

To describe the normal patterns of cerebellar activation in specific cerebral functions (motor, language, memory) and their topographical correlations in the cerebellar cortex on functional magnetic resonance imaging.

Materials and methods

We evaluated 25 healthy subjects (8 women and 17 men; 23 right-handed and 2 left-handed; age range, 16–64 years), who did language, memory, and motor tasks while undergoing 1.5T functional magnetic resonance imaging.

Results

We assessed functional activity of the cerebellum associated with motor, language, and memory components, describing their relations with topographical regions of the cerebellum and their functional relations with areas in the cerebral cortex.

Conclusions

Knowledge of the normal patterns of morphological characteristics and functional behaviour in the cerebellum as well as their relations with the brain is important for radiologists and clinicians evaluating the cerebellum and possible pathological conditions that affect it.

Resumen
Objetivos

Describir los patrones normales de activación en el cerebelo de funciones específicas cerebrales (motor, lenguaje, memoria) y su relación topográfica en la corteza cerebelosa utilizando resonancia magnética funcional.

Materiales y métodos

Se evaluaron 25 sujetos sanos, 8 mujeres y 17 hombres de entre 16 y 64 años, 23 diestros y 2 zurdos, mediante resonancia magnética funcional basada en tareas de lenguaje, memoria, motor y visual, en equipo de resonancia de 1.5 Teslas.

Resultados

Se caracterizó la actividad funcional en el cerebelo asociada a los componentes motores, de lenguaje y memoria, describiendo la relación con las regiones topográficas, así como su relación funcional con áreas corticales cerebrales.

Conclusiones

El conocimiento sobre los patrones de normalidad de las características morfológicas y del comportamiento funcional en el cerebelo, así como su relación con el cerebro, es importante para el radiólogo y médico clínico en la evaluación del cerebelo y sus posibles condiciones patológicas.
