T1: Neuro Development

Question 1

The neural mechanisms constitute…

Answer 1

proximate causes of behavior

Question 2

Receptor cells acquire sensory information form the environment…

Answer 2

interneurons process the information– nerves– CNS— responses

Question 3

Different species…

Answer 3

different neural mechanisms — tasks are performed differently —- species differ in their behavior

Question 4

At the ultimate levels (ultimate causes of behavior) animals differ in …

Answer 4

their neurophysiology because of different selection pressure

example) star nosed mole

Question 5

What is unique about the star-nosed moles

Answer 5

• highly developed touch to identify prey in the darkness
  -22 tiny trunks
  -the tentacles sweep ahead like a high-speed broom

Question 6

What are the other traits about the star-nosed mole

Answer 6

these appendages are covered with thousand of tiny sensory devices “ elmer’s organs”

-somatosensory cortex = the information from the nose

Question 7

what is the definition of the cortical magnification

Answer 7

it is preserved across mammalian species

-different areas of the somatosensory surface are magnified depending on the behavioral relevance of the corresponding sensors
