presynaptic dopaminergic neuron‚ lithium in acute administrations‚ inhibits the release of DA by binding onto the dopamine-specific (D1-D5) autoreceptors (Prasad‚ 2010). These autoreceptors serve as a mechanistic negative feedback loop that controls the release of DA and regulates its levels in the synaptic cleft. Lithium acts as an agonist on these autoreceptors and therefore inhibits the turnover of DA resulting in either increased reuptake or inhibited release from the presynaptic neuron. However this

Regulatory Behavior Emily Beecher PSY/340 April 27‚ 2015 Dr. Annie Powers Regulatory Behavior The nervous system is an extremely elaborate biological machine. Without question‚ the nervous system is a system so intricate and comprehensive that professionals in the field of medicine to this day do not have a “complete picture” of each of the working details of the human nervous system. Of these different mechanisms‚ perhaps the one most riddled with speculation‚ is the mechanism of sleep. In discussing

What was the threshold voltage‚ or the voltage at which you first saw an action potential? 3.0 V 3. How does this tracing compare to the one that was generated at the threshold voltage? The tracing travel in the same fashion but the tracing were different with an increase threshold voltage 4. What reason can you give for the change? Increase voltage 5.

nervous system there would be no way to get information from the brain to the rest of the body; all the messages that our brain sends out must be sent though the nervous system through neuron communication. "Neurons communicate with each other using axons and dendrites. When a neuron receives a message from another neuron‚ it sends an electrical signal down the length of its axon. At the end of the axon‚ the electrical signal is converted into a chemical signal‚ and the axon releases chemical messages
