  • (circle the appropriate word) Recordings of neurons along [oblique] / [vertical] trajectories through visual cortex yield neurons with different directional tuning preferences.

  • Which type of bipolar neuron is depolarized by the neurotransmitter glutamate?

  • Ganglion cells of which type have responses to light that are analogous to Pacinian corpuscle responses to touch?

    A. right-upper V1
    B. right-lower V1
    C. left-upper V1
    D. left-lower V1

    A. lateral superior olivary nucleus
    B. primary auditory cortex
    C. medial geniculate body
    D. medial superior olivary nucleus

  • True / False - The responses of cochlear nucleus neurons to pure tones are homogenous and like those of cochlear ganglion cells

  • Low-frequency tones produce the most oscillation at this part of the basilar membrane which is:
    A. base, narrow and floppy
    B. base, wide and floppy
    C. apex, narrow and stiff
    D. apex, wide and floppy

  • Neuron A responds to an isolated 10 KHz tone by firing 3 action potentials per second. However, if preceded by a 5 KHz tone, the same neuron's response to the 10 KHz tone is to fire 20 action potentials per second. This is a good example of _____ _____.

  • Circle the appropriate answer - The bat uses [ FM delay ] / [ CF delay] to determine target distance, but uses [ interaural time differences ] / [ CF pitch shifts ] to determine target velocity.

  • A neurotransmitter, upon binding to a post-synaptic receptor, begins a 2nd messenger cascade that changes the kinetics of a voltage-gated Ca++ channel. The neurotransmitter is of what type?
    A. ionotropic
    B. metabotropic
    C. it's not possible to know
    D. cationotropic

  • Name 4 neuromodulatory neurotransmitters and two properties common to all neuromodulatory systems

  • NE acting on a neuron only slightly changes its membrane potential, but nevertheless doubles that neuron's response to input from another neuron. This is one example of how neuromodulatory systems change the operation of brain circuits or, in other words, how they sometimes change the _____ _____ of the brain.

  • Name three cell types that each exhibit spatially-specific firing according to the allocentric frame of reference.

  • Circle the appropriate word. The [GPi] / [GPe] is part of both the direct and indirect pathways through the basal ganglia. Medium spiny neurons of this region utilize [D1] / [D2] dopamine receptors which [enhance] / [suppress] their response to cortical excitatory inputs.

  • True / False Dopamine neurons fire more action potentials when expected reward is less than actual reward.

  • True / False Local field potential (LFP) amplitudes typically depend on the coherence level of synaptic inputs to the dendrites of a population of neurons.

  • Two types of voltage-gated Ca++ channels and two types of K+ channel are implicated in the intracellular membrane potential oscillations of thalamic and cortical neurons which accompany LFP 'slow-waves' in the thalamus and cortex.
