PSL300: tweed 2: introduction to the senses Questions With
Complete Solutions
adequate stimulus and example Correct Answers form of
energy to which a receptor is most responsive, thermoreceptors
most sensitive to temperature
apart from modality, what info do sensory neurons carry Correct
Answers intensity
are temporal changes the only changes it's efficient to report
Correct Answers nope spatial too
are the different terms for nerve cells loosely used in PSL
Correct Answers yes
are we usually partly conscious of data from these 9 senses
Correct Answers yes
at cells outside area of contact where an object is pressing into
the skin, are only the cells at the area of contact firing Correct
Answers no, the areas outside the contact area are at baselin
can both frequency coding mechanisms operate together Correct
Answers yes
can inhibition and activation of neurons sum up Correct
Answers yes, important in lateral inhibition
can the brain be fooled and why Correct Answers yes, since it
has to guess
, contrast Correct Answers another word for spatial change
convergence Correct Answers when many presynaptic cells
may contact any one post-synaptic cell.
different kinds of neurons Correct Answers primary, secondary,
tertiary
do all fibres of the equilibrium pathways go through the
thalamus Correct Answers nope, only some of them.
do all neurons fire action potentials Correct Answers no
do receptors only respond to one type of energy? example
Correct Answers a lot of them respond to other forms of energy
as well. some thermoreceptors respond to certain chemicals
photoreceptors designed to respond to light can respond to
vibration
do sensory neurons carry out info about only the type of
sitmulus Correct Answers nope, may
do sensory systems involve just one neuron Correct Answers no
they involve sets
do the other forms of energy have to be pretty powerful to
activate a receptor with a different adequate stimulus Correct
Answers yes.
