Question 1

Understanding the exact location of a sensation, along with ones body position before/after a sensation occurs is dependent on 2 things. What are they?

Answer 1

1. ) How the sensation is encoded
2. ) How we perceive the sensation at a conscious level

Question 2

Define Sensation

Answer 2

The process where sensory receptors recieve info from both the internal and external environment and encode the info for transmission to various areas of the nervous system

Question 3

Sensation includes 4 different process that intergrate signals centrally by either facilitation (depolarization) or inhibition (hyperpolarization). What are they?

Answer 3

1. ) Sensory transduction
2. ) Receptor Potential Summation
3. ) Action Potential Generation
4. ) Neural Processes

Question 4

Facilitation is affiliated with:

Depolarization or Hyperpolarization?

Answer 4

Depolarization

Question 5

Inhibition is affiliated with:

Depolarization or Hyperpolarization?

Answer 5

Hyperpolarization

Question 6

Define Perception

Answer 6

The process where the CNS receives and interprets the sensations based on present experiences, the present state of the internal and external environment, and the memory of similar situations

Question 7

Perception is defined as the process where the CNS recieves and interprets the sensations based on what 3 things?

Answer 7

1. ) Present experiences
2. ) Present state of the internal/external environment
3. ) Memory of similar situations

Question 8

Perception occurs in various degrees of refinement in the…(4)

Answer 8

1. ) Thalamus
2. ) Basal Ganglia
3. ) Cerebellum
4. ) Cortex

Question 9

Perception at what level of the brain is considered “unconscious perception”

Answer 9

Cerebellum

Question 10

Perception at what level of the brain is considered “conscious perception”

Answer 10

The Cortical Level

Question 11

Besides the Cerebellum what other structure may be involved in unconscious perception?

Answer 11

Basal Ganglia

Question 12

What structure of the brain is involved with unconscious representations of movement experiences?

Answer 12

Basal Ganglia

Question 13

Aside from unconscious representations of movement experiences what else are Basal Ganglia responsible for?

Answer 13

The perception of inter and intrapersonal space

Question 14

Without what part of the brain are perceptions incomplete or skewed from normal?

Answer 14

The cortex

Question 15

Without the cortex perceptions are skewed and result in….(3)

Answer 15
