Neurophysiology

Step 1: Understanding Neurotransmitter Effects
- Cocaine blocks dopamine reuptake, leading to prolonged stimulation of the brain's reward system.
- Charas, Heroin, and Morphine affect other neurotransmitters like endorphins and opioids, but not dopamine transport.

- Thermoreceptor sensillae in cockroaches are primarily found on the first three tarsomeres of the legs, which help in detecting temperature changes.
- The thorax and abdomen contain other sensory structures but not thermoreceptor sensillae.
- The trochanter is a part of the cockroach's leg but does not specifically house thermoreceptor sensillae.
