39 Sensory Systems

Question 1

describe the components and processes of a sensory receptor cell

Answer 1

Question 2

describe a cell’s response in encoding intensity

Answer 2

Question 3

describe slowly adapting (tonic) receptors

Answer 3

Question 4

describe rapidly adapting (phasic) receptors

Answer 4

Question 5

small receptive fields have ____ spatial resolution

and

large receptive fields have ___ spatial resolution

Answer 5

small receptive fields have high spatial resolution

and

large receptive fields have low spatial resolution

Question 6

Answer 6

Question 7

describe lateral inhibition

Answer 7

• lateral inhibition is a computation that improves spatial resolution
  
  • overlapping receptive fields
• uses excitatory and inhibitory input at second-order neurons
• the most active neurons limit the activity of adjacent, less active neurons
• lateral inhibition enhance stimulus contrast (signal vs background) throughout successive relays
