Front 1

Cerebral Cortex: Physiology

Back 1

Sensory perception
Voluntary control of movement
Language
Personality traits
sophisticated mental events, such as thinking memory, decision making, creativity, and self-consciousness etc

Front 2

Cerebral Cortex: frontal lobe

Back 2

voluntary motor activity, speaking ability, elaboration of thought.
Primary motor cortex, motor control -MOTOR HOMUNCULUS (little man)

Front 3

Cerebral Cortex: parietal lobe

Back 3

receiving and procesing sensory input.
Somatosensory processing, intensiry proprioceptive input, spatial discrimation - SNESORY HOMUNCULUS (sensation)

Front 4

Cerebral Cortex: occipital

Back 4

initial processing of visual input

Front 5

Cerebral Cortex: Temporal

Back 5

integration of all sensory input

Front 6

Cerebral Cortex: frontal lobe: other regions important for motor control

Back 6

- premotor cortex
- supplementary motor cortex
- Posterior parietal cortex
- command the PMC?

Front 7

Cerebral Cortex: somatotopic areas

Back 7

- mapping varies slightly b/t individuals
- Are in dynamic steady state, not static
- areas influenced by use-dependent competition
- areas modified by experience
- plasticity of the brain: can be remodeled in resonse to varying demands-individuality ex. learn playing guiltar

Front 8

broca's area

Back 8

motor areas - speaking ability

Front 9

wernicke's areas

Back 9

visual/aditory - language comprehension

Front 10

Cerebral Cortex-associatetive areas: prefrontal association cortex

Back 10

panning for voluntary activity, decision making, creativity and developing personal traits

Front 11

Cerebral Cortex-associatetive areas: parietal-temporal-occipital association cortex

Back 11

integration of somatic, auditory, and visual sensations from 3 lobes

Front 12

Cerebral Cortex-associatetive areas: limbic association cortex

Back 12

motivation, emotion and memory

Front 13

cerebral hemispheres: left

Back 13

thinkers:
- language
-fine motor control, therefore most people right-handed
-Excels in logical, analytical, sequential, and verbal tasks
-Process information in fine-detail, fragmentatry way

Front 14

cerebral hemispheres: right

Back 14

Creator:
excels in spatial perception and artistic and musical talents
-Process information in a gib picture, holistic way

Front 15

Basal nulcei/bsal ganglia

Back 15

Inhibitory role in motor control, including:
- inhibit muscle tone throughout the body
-select and maintain purposeful muscle activity while inhibit useless movement
-Monitor and control slow, sustained contractions

Front 16

Thalamus

Back 16

-Relay station and synaptic integrating center for processing sensory input on its way to cerebral cortex
- Important for motor control
Screens out insignificant signals and routes important sensory impulses to areas of somatosensory cortex.
-Directs attention to stimuli of interest.
-Capable of crude awareness of sensation.
-Some degree of consciousness

Front 17

hypothalamus

Back 17

Regulates many homeostatic functions:
1. control body temp
2. control thirst and urine production
3. control food intake.
4. control anterior pituitary hormone secretion
5. production of posterior pituitary hormone
6. control uterine contractions and milk ejection
7. serves as an ANS coordinating center
8. Plays a role in emotional and behavioral patterns

Front 18

limbic system

Back 18

plays key rol in:
1. emotions
2. basic survival
3. socialsexual behavioral patterns
4. motivation
5. learning
-Has a reward and punishment centers
- Norepineprine, dopamine and serotonin and important NT

Front 19

Cerebellum

Back 19

1. maintain balance,
enhances muscle tone,
coordinate/plans skilled voluntary muscle activity (dancing.
1. regulation of muscle tone, coordination of skilled voluntary movement
2. planning and initiating of voluntary activity
3. maintenance of balacne, control of eye movements.

Front 20

brainstem

Back 20

control life-sustaning process:
1. respiration
2. circulation
3. digestion (vegetative function)

Front 21

brainstem: vital link b/t spinal cord and higher brain regions

Back 21

1. most of cranial nerves are connected to the brain stem
2. heart and blood vessel control center
3. modulates the sense of pain
4. role in regulating muscle reflexes involved in equilibrium and posture
5. reticular formation ranges from the brainstem to the thalamus; control cortial alertness and direct attention
6. has sleep centers
