- FIGURE 3.
Typical neuron consisting of central cell body, axon, and dendrites. (Reprinted with permission from (3).)
- FIGURE 4.
Impulse conduction at synapses. Shown is impulse conduction from presynaptic end bulb across synapse to postsynaptic dendrite in which synaptic vesicles fuse with presynaptic membrane and discharge neurotransmitter into synaptic cleft. (Reprinted with permission from (3).)
- FIGURE 5.
Transaxial 123I-IBZM images show cortical uptake and specific binding to D2 or D3 DA receptors. Striatum is well visualized with this radiotracer because of high density of DA receptors in region. Focal areas of activity inferiorly in image are external fiducial markers placed along canthomeatal line.
- FIGURE 6.
123I-IOM uptake reflects distribution of benzodiazepine receptors in cortex of brain. Medications such as diazepam bind to this site.
- FIGURE 7.
123I-5-I-A distribution within thalamus indicates location of nicotinic cholinergic receptors, where drugs such as nicotine bind.
- FIGURE 8.
123I-β-CIT images of neuronal loss over time in patient with Parkinson’s disease. (A) Striatal uptake of radiotracer. (B) Decreased uptake in left striatum.
