What are the three parts of the brain according to Paul MacLean's Triune Brain Hypothesis?
|
1. Reptilian complex (brainstem and cerebellum) (instinctual survival behavior, unconscious)
2. Limbic System (emotions, personality, some memory, subconscious, the four F's) 3. Neocortex (higher thinking skills, reason, consciousness, problem solving, reason and speech) |

|
What is the falx cerebri?
|
an extension of the dura mater - projects into the longitudinal fissure down to the corpus collosum
|
|
|
|
Gray matter
|
outermost portion of the cerebrum - forms the cerebral cortex. neuron cell bodies and unmyelinated fibers
|
|
|
|
white matter
|
bulk of the cerebrum - myelinated nerve fibers
|
|
|
|
basal ganglia
|
areas of gray matter scattered in white matter. connects cerebrum to deeper structures such as the thalamus

1. frontal lobe
2. parietal lobe 3. occipital lobe 4. insula 5. temporal lobe |
|
|
|
Functions of the frontal lobe include?
|
personality

|
parietal lobe?
|
located under parietal bone - sensation and integration of visual/tactile sensations
|
|
|
|
insula
|
emotion, homeostatic regulation.
lies deep within lateral sulcus. covered by parts of the frontal, parietal and temporal lobes. |
|
|
|
Temporal lobe?
|
hearing and smell. lateral sides of brain, inferior to frontal and parietal lobes
|
auditory cortex
olfactory cortex |
|
|
What is the cerebral cortex?
|
Center for sensory and motor functions. Concerned with memory, language, reasoning, intelligence and personality.

|
Gustatory cortex?
|
receives input from taste buds, permits perceptions of different tastes.
parietal lobe |
the chef (gusta ~ gastric)

|
|
Primary motor cortex?
|
conscious control of skeletal muscle contraction. right motor cortex controls left side of body. neurons in specific regions control muscles in specific body areas. frontal lobe
