Brain Study Guide
The Brain Depolarization: positive ions, more likely action potential Hyperpolarization.: negative ions, less likely (Types Of) Neurotransmitters ? Chemicals that bind to receptor sites ? Impact/influence receiving neuron ? Reabsorbed into sending neurons through process of reuptake ? Applies brake on neurotransmitter?s action ? Serotonin pathways - involved w mood regulation ? Dopamine pathways - involved w diseases such as schizophrenia & Parkinson?s ____________________________________________________________________________ Neurotransmitter Function Examples of Malfunctions _____________________________________________________________________________ Acetylcholine (ACh) Muscle action, Deterioration: Alzheimer?s learning & memory
