A neuroscientist trying to figure out how the brain does it all. I use MRI and data science methods to study neurophysiology and structure. Currently leading a team of undergraduates in a novel study.

Draw the tracts
Using the CNS worksheets (see Haines pg. 253) or a blank sheet of paper, the inputs and outputs of the:
- Posterior Cerebellar lobe
- Anterior cerebellar lobe
- Flocculonodular lobe
| Anatomic | Phylogenic | Functional |
|---|---|---|
| Anterior Lobe | Paleocerebellum | Spinal cerebellum |
| Posterior Lobe | Neocerebellum | Cerebral cerebellum |
| Flocculonodular Lobe | Archicerebellum | Vestibular cerebellum |
Give the names of the cerebellar lobes
Name the Lobe
Name the structure

Where do the inputs to the posterior lobe of the cerebellum decussate?
- Rostral pons
- Caudal midbrain
- Middle pons
- Rostral medulla
Where do the outpurs from the posterior lobe of the cerebellum decussate?
- Rostral pons
- Caudal midbrain
- Middle pons
- Rostral medulla
Name the tract
List the signs and symptoms of posterior lobe syndrome
- Intention tremor
- To-and-fro movements perpendicular intended direction of movement
List the signs and symptoms of anterior lobe syndrome
- Gait ataxia
- Clumsy movements of the lower limbs
List the signs and symptoms of flocculonodular lobe syndrome
- Truncal ataxia
- Walks with a wide base and with constantly reeling trunk.

A 23 YOM is brought to the ED after a motor vehicle accident. He presents with weakness in the right lower extremity and loss of pain and thermal sensation on his left side beginning at the umbilicus. Damage to which tracts would explain the observed weakness?
- Left corticospinal tract
- Reticulospinal fibers on the right
- Right lateral corticospinal tract
- Right rubrospinal fibers
- Vestibulospinal fibers
