Lecture 22: Structure and layout of major brain areas; Sensory and motor pathways Flashcards
What are the parts of the brainstem
Midbrain, Pons, Medulla oblongata
What are the functions associated with the frontal lobe
Language
Personality
Motor control
What are the functions associated with the Pareital lobe
somatosensory
What are the functions associated with the Occipital lobe
Vision
What are the functions associated with the Temporal lobe
Memory
Hearing
What two structures make up the diencephalon
Thalamus and Hypothalamus
Why is the brain folded to be smaller
Smaller brains = smaller heads
easier for childbirth which is already hard
Where is the choroid plexus found
In the lateral ventricles
What are the 3 types of white matter
Commissural tracts
Projection tracts
Association tracts
What part of the brain functions as the primary motor cortex
Precentral gyrus (Frontal lobe)
What part of the brain functions as the primary somatosensory cortex
Post central gyrus (Parietal lobe)
What does damage to the motor cortex in the brain cause
Muscle weakness and paralysis in reigon of the body corresponding to the location of damage
What is associated with the Dorsal/Posterior Column Pathway
Fine touch, vibration, pressure, proprioception
What is associated with the Spinothalamic Tract
Pain, Temperature
What is an Agnosia
Damage to a region involved with
sensory perception
Causes changes in perception
What is an Aphasia
Damage to regions governing
language
Causes changes in perception or production
