Lecture 13- Cerebellum Flashcards
Layers of the cerebellum
Molecular (outermost)
Purkinje (middle)
Granular (innermost)
What type of fibers innervate the granular layer
Mossy fibers
What type of fibers innervate the molecular layer?
Climbing fibers
What NT do Purkinje cells use?
GABA to decrease neuronal activity
Symptoms of a cerebellar lesion
Generalized ataxia, functioning UMN and LMN, hypermetria (overshooting movements), Intention tremors, vestibular disease
Three types of ataxia
Proprioceptive, cerebellar, and vestibular
What causes cerebellar hypopalsia?
In utero infection of parvo or feline panleukopenia
Symptoms of cerebellar hypoplasia
Hypometria, ataxia, intention tremor
When is an action tremor triggered
When trying to walk
White Shaker Dog Syndrome physiologic cause
brain produces an antibody to GABA
Other name for White Shaker Dog Syndrome
Steroid responsive tremor syndrome
