Dorsal stream
From the occipital cortex what is the stream that is involved with “what”?
Ventral stream
Where does the brain make at 90 degree turn during development?
mesencyphalon
If there are problems with the anterior limb of the internal capsule what is the resulting presentation?
Motor diseases, ataxia, tremors
Where do the fibers for each of the following starting location go to in the anterior limb of the internal capsule:
- thalamus to:

- cortex to:
- frontal lobe to:
- frontal lobe
- caudate nuclei
- corpus striatum
- pontine nuclei
The anterior 2/3 of the posterior limb of the internal capsule is mostly fibers from what?
corticospinal tract
Where are sensory fibers in the posterior limb of the internal capsule mostly from? 1 And also may be from where? 2
- thalamus
2. medial lemniscus
What are the fibers that pass through the posterior limb of the internal capsule that are from the lower visual centers to the cortex of the occipital lobe?
fibers of Optic radiation
Where does the acoustic fibers of the posterior limb of the internal capsule get its info from and where is it taking it to?
From lateral lemniscus to the temporal lobe
Where do all motor from somatotopic pass through?
posterior limb of the internal capsule
Where is damage to the neuron if there is spastic paralysis? 1. Flaccid paralysis? 2
- upper motor lesion
2. lower motor lesion
What are the structures of the lateral ventricles?
- anterior horn
- body
- trigone
- posterior horn
- inferior horn
What type of matter is the caudate nucleus?
gray
Where is the head of the caudate nucleus in relation to the lateral ventricle? 1. Where is the tail of the caudate nucleus in relation to the lateral ventricle?
- immediately lateral to anterior horn
2. superior to inferior horn
What is the connection between the putamen and caudate?
lentiform nucleus
What is the structure at the center of the brain that is a collection of nuclei deep in the cerebral hemisphere and is responsible for stopping unwanted messages and makes motor movements smooth?
Basal ganglion
What are the five main nuclei of the basal ganglion?
- putamen
- globus pallidus
- caudate
- subthalamic nuclei
- substantia nigra
What nuclei of the basal ganglion are darker than the rest?
putamen and caudate
What nuclei of the basal ganglion is in the diencephalon?
subthalamic nuclei
What nuclei of the basal ganglion is in the mesencephalon?
substantia nigra
If there is damage to any of the nuclei of the basal ganglion what motor disfunction will there be?
dyskinesia, with resting tremor
