Part of the Brain

Description/Function

Symbol/Mnemonic Device

Brainstem

Medulla




Unconscious vital processes (circulation, heart rate, breathing)

“medusa” turns to stone

Doulah = midwife (brings life)

“med”-itation

Just “du” it (me-“du”-lla)

Breathing is “dull”

Me-du-llah sounds like heartbeat




Pons




Communicates sensory messages & movement from cerebellum to cerebrum
“Bridge”
Eye and face movements
Possible role in dreams


Pom-pons
Bridge over a pond



Reticular Formation

(Reticular Activating System)


Arousal & attention
Filters stimuli coming to brain

“Rise And Shine” (R.A.S.)

Particular Reticular (filters stimuli)


Re-“tic” ular formation (tic – sound of neural firing)




Cerebellum





Muscle coordination & balance

Cere-“bal”-um

Cere-balance

Sarah-Ballerina

Two “ll”s look like balance beam

CereBelluM – Coordination, Balance, Movement

Belle of the ball (dancing = balance & coordination)

Antebellum (balance between slave & free)

Ball (need coordination to catch)





Thalamus




Directs sensory information to particular areas of brain

Thal-mail (like a post office)

T-top of brainstem, S-switchboard




Amygdala




Instinctual emotional reactions (aggression or fear)
Attention to novel stimuli

Amygdala monster

“Angry Amy” or Aggressive Amy

Emo-gdala


Hypothalamus





Regulates hunger, thirst, body temperature, endocrine system

Hungry “hypos”

Hypo-thermometer, hypothermia

Hyper-hypothalamus

Hypo - typo (regulation/maintenance)

Hypothala “must”

Hypothalamus

Homoeostasis

M=maintenance



Pituitary Gland

Master gland – directs endocrine system

Arm “pit”

Pit boss (directs casino activities)



Hippocampus





Formation of new memories

Hippo at camp (can’t forget that!)

Camping – make memories

“One time at hippo camp”

Hippos never forget (similar to elephants)




Cerebrum

Cerebrum




Divided into two hemispheres
Higher order functions

Cereal bowl
Cranium game

Left Hemisphere





Logic, language (verbal tasks), math, detail-oriented
Controls right side of body

Logical-left (lefty-logic)

Left-logic-language



Right Hemisphere





Visual-spatial tasks, creativity
Controls left side of body

R-tistic

Right Rembrandt

Right Sight


Corpus Callosum





Thick bundle of nerve fibers that connects left & right hemispheres
Communicates between two hemi’s


Callo-“sum” of 2 hemispheres

Corpus “Call someone” (connects)

Corpse – connects living & dead???

Connection Cord

Cor“plus” callosum (two hemispheres together)



Cerebral Cortex

Cerebral Cortex





Wrinkled surface of brain
Divided into four lobes

Crinkled Cap

Cor-Texas (large surface area)

Core-tex (core of higher functions)


Frontal Lobes





Emotion regulation, speaking, judgment & reason, planning, personality

Personality is a “front”

“Future” lobe

Prefrontal lobotomies

Frontal filter (for emotions)



Parietal Lobes





Pain, pressure, touch sensations

Presents-parietal (receiving info)

Parietal-pain-pressure-position

Temporal Lobes





Auditory cortex (hearing)

Tempo (music/rhythm)

Temple (temples on side of head)



Occipital Lobes





Visual cortex (sight)

Eye-cipital lobe

“ocular” occipital



Optometrist/ophthalmologist

Occipital sounds like “optical”



Motor Cortex





Located at rear of frontal lobes
Controls voluntary movements





Sensory Cortex





Located at front of parietal lobes
Receives info for body touch & movement sensations




Association Areas



Broca’s Area



Physical production of speech (directs muscle movements)


Located in left frontal lobe

Broca Obama


Boca = “mouth” in Spanish

Wernicke’s Area*




Language comprehension & expression


Located in left temporal lobe

“Hooked on Wernicke’s” (like the


“Hooked on Phonics” program)

Basal Ganglia – collection of nuclei (at base of the hemispheres) for controlling voluntary movements and establishing postures


Glial Cells – nourish, protect, and support neurons
* Angular Gyrus – transforms visual representations into auditory code (Wernicke’s area uses this auditory code to derive meaning)

 Damage to angular gyrus means someone can speak & understand, but cannot read aloud


*Locus Coeruleus – role in physical reaction to panic/stress
