a. Biogenic amines
2. Most common excitatory NT in CNS:
a. Glutamate
3. Postsynaptic activations in rapid succession, leading to ______ postsynaptic potentials
a. Temporal activations, leading to graded potentials
i. NOTE: this can sum up to an action potential *** there is definitely the
potential, but it is not guaranteed
4. Ligand-gated channel of postsynaptic receptor opens to allow ______ influx; resulting in action
potential or EPSPs along postsynaptic neuron
a. Sodium
5. Remembering & performing specific sequence, which type of neuronal circuit?
a. Reverberating
6. 3 ways to classify sensory receptors:
a. Stimulus location/type, complexity of structure
7. ___ is where energy of the stimulus is transformed into electric activity
a. Transduction
8. Correct order for stimulus reception/transduction:
a. Stimulus, opening of ion channels, receptor potential, action potential
9. Intensity is determined by action potential _____.
a. Frequency
10. T/F phasic receptor adapts faster than a tonic receptor
a. True
i. ***recall phasic is easier to remember
11. Initial response of a receptor decreases over time… what is this process called?
a. Adaptation
12. Slowest adapting receptors in our body?
a. Nociceptors
13. Hair cells receptive to changes in dynamic equilibrium are found in this structure:
a. Crista ampularris (in semicircular canals)
14. Chemically sensitive cilia are found in this structure:
a. Olfactory epithelium

a. Dark
28. Visual inputs to ____ serve to synchronize biorhythms
a. Suprachiasmatic nucleus
