|
Cerebral Cortex
|
Outer Region
2 - 4 mm thick highest order of brain function Most complex and least understood |
|
|
Frontal Lobe Contains
|
Primary Motor Cortex - Concouse control of voluntary movement
Premotor Cortex - Coordinates movement with sensory info Prefrontal Cortex - most rostral region, Personality, cognition, concoius thought |
|
|
Phinous Gage
|
iron through prefontal cortex of cerebrum, total change in personality
|
|
|
Parietal lobe
|
Integrates Sensory Info, THE SOMATOSENSORY CORTEX - recieves and intereprets general somatic senses (touch, pressure)
|
|
|
Humunculus
|
Somatosensory cortex - exibits somatotropy = body mapping,
|
|
|
Alzheimer's
|
Parietal Lobe, Basal forebrain nuclei
|
|
|
Temporal Lobe
|
Auditory Cortex - recieve and interprets auditory stimuli
Olfactory Cortex - "" "" smelling stimuli This is greatly reduced and reserved for limbic system |
|
|
Insula
|
Balance, Taste, Integrates Sensory info, Emotion
|
|
|
White matter (deep to cortex)
|
Myelinated tracts -for communication in different brain regions... Commiseral Fibers, Association Fibers, Projection Fibers,
|
|
|
Commiseral Fibers
|
Connect cooresponding areas of left and right hemispherses... aka corpus collosum...
|
|
|
Association Fibers
|
Connects within a single side of cerebral cortex
|
|
|
Projection Fibers
|
Connect cortex to rest of nervous system...
|
|
|
Deep grey matter of cerebrum
|
Contains Basal ganglia, and basal forebrain nuclei...
|
|
|
Basal Ganglia
|
Not actually Ganglia, Unconscious control of movement. repetetive rythmic movement, start and stop, intensity
|
|
|
Parkinsons
|
Issue with Basal Ganglia and substantia Nigra... used deep brain stimulation to treat
|
|
|
Basal Forebrain Nuclei
|
play role in memory ... first area to show problems in Alzhiemers
|
|
|
Diencephelon Contains
|
Thalamus, Hypothalamus, Epithalamus,
|
|
|
Thalamus
|
Relay station to cerebral cortex, all incoming sensory inputs go through thalamus, Amplifies and filters sensations..
|
|
|
Hypothalamus
|
Center of Homeostasus, Hunger, thermoragulation, sex... Secretes Hormones,
Biological clock - maintains circadian rythm |
|
|
Epithalamus
|
contains pineal gland which secretes melatonin (hormone)... convays circadian rythm from hypothalamus to rest of body
|
|
|
Mesencephalon contains...
|
= midbrain... which contains Corpora Quadrigemina and Substantia Nigra
|
|
|
Corpora Quadrigemina
|
four rounded portrusions in dorsal midbrain...
Superior Colliculi - visual reflex Inferior Colliculi - auditory reflex |
|
|
Substantia Nigra
|
(highly pigmented by melonin)
Inhibits Basal Ganglia Degeneration results in parkinson's |
|
|
Metencephalon Contains...
|
Pons, Cerebellum
|
|
|
Pons
|
Between midbrain and medula oblongata ... mostly white matter...Tracts connecting cerebrum to cerebellum ...
|
|
|
Cerebellum
|
Major Coordinator of Movement ... smoothed out blueprint.. Damage to it causes poor balance ... contains half of all neurons in the brain ... also plays role in cognition
|
|
|
Family that walks on all fours
|
Cerebral defect...
|
|
|
Myelencephalon contains...
|
Medulla Oblongata
|
|
|
Medulla Oblongata
|
Most caudal region of brain ... relay station between spinal chord and rest of brain ... Autonomic control of visceral organs (heart rate, body temp, respiration) ... damage causes respiratory failure...
|
|
|
Functional Brain Systems...
|
Scattered throughout the brain but closely related in function
|
|
|
Reticular Formation
|
Primary Brainstem: midbrain, pons, medula
Arousal Alertness: reticular activating system...Anesthesia and tranqs inhibit RAS... Damage of RAS = COMA |
|
|
Limbic System Contains
|
Amygdala: fear
Cingulate Girus: emotion Hippocampus: long term memories - effected by alzhiemers |
