Touch/Pain
Type of receptor that can detect pain or temperature
What is nociceptor?
Place where odorants bind to their receptors
What is the olfactory epithelium?
Names of the 3 ossicles
What are incus, stapes and malleus?
Animal that see UV frequencies
What is a bird? Also a mantis shrimp
A sensory system that sends information across the midline
What is touch? Also, pain, hearing and vision. Keep in mind that hearing sends information to both sides of the brain to allow for detecting where a sound came from
True or false: A single somatosensory axon can conduct information about touch and pain
What is "false"?
Name of receptor/cell type that allows you to taste capsacin
What is TRPV1? Capsacin binds these temperature sensing receptors on the tongue
True or false: Vibrations in the cochlea have the same frequency and amplitude as the initial sound wave that entered the ear.
What is "true"? *The exception is if the sound is too loud and the ossicle muscles stiffen to reduce the amplitude to protect the cochlea*
Color(s) that a blue and green fish will appear under green light
True or false: Receptor potentials are all the same amplitude
What is "false"? The size of the receptor potential can determine how many action potentials will be fired or how much neurotransmitter is directly released onto the next neuron.
Receptor that is activated when your skin gets stretched
What is Ruffini's ending?
Name of the auditory topographic map
What is tonotopic map?
Name of the receptive field of an auditory neuron
What is a tuning curve?
True or false: A single photon opens hundreds of sodium channels in a rod
What is "false"? A photon CLOSES hundreds of ion channels
Receptor cell that is a neuron
What is touch/pain cells? Also olfactory cells (but not taste, hearing or rod/cone cells)
True or false: The information carried by Adelta fibers CAN cause you to reflexively pull your hand away from a hot pan.
What is "true". The information carried by Adelta fibers is about very hot temperatures (pain).
Reason that when you eat a chili pepper, it takes a few seconds for your tongue to start burning
What is "C-fibers are unmyelinated"?
Part of the basilar membrane activated by high frequencies (stiff or floppy)
Where is the stiff part closest to the oval window?
The dorsal visual pathway processes information about this
What is "where"?
Light wave frequency conveys information about ____, while sound wave frequency conveys information about ____.
What are color and pitch?
Nociception receptor that allows you to sense cold
What is CMR1?
Information about odors first enters this brain region
What is piriform cortex?
Two things that determine whether an auditory neuron will be activated by a sound
What are frequency (pitch) and loudness?
Characteristic that simple neurons in V1 detect
What is bars? Also, edges
Sensory system does not immediately convert external stimuli into an electrical signal
What is hearing?
