Question 3

Receptive fields give rise to

Answer 3

Maps

Question 4

Pathways

Answer 4

“Neural relays”; let our sensory systems build upon and talk to each other

Question 5

Afferent neurons

Answer 5

Sensory neurons; impulses from sensory stimuli towards the CNS

Question 6

Efferent neurons

Answer 6

Motor neurons; impulses away from CNS (usually to muscles) for response

Question 7

Efferent

Question 8

Presence of a stimulus is encoded by…

Answer 8

An increase or decrease in a neuron’s firing rate

Question 9

What codes intensity?

Answer 9

Amount of change in neuron’s firing rate

Question 10

The McGurk Effect

Answer 10

Occurs when the perception of speech is influenced by both auditory and visual information, leading to a perceptual experience where the visual cues impact the interpretation of the auditory speech sounds
