Study Notes
- The lecture covers the structure and function of cells in the nervous system.
- Neurons have a soma, dendrites, axon, and terminal buttons.
- Neurons can be divided by function into sensory, motor, and interneurons.
- Neurons can be divided by structure into multipolar, bipolar, and unipolar neurons.
- Supporting cells in the nervous system include astrocytes and oligodendrocytes.
- The blood-brain barrier regulates the flow of nutrient-rich fluid into the brain.
- Neurons communicate through action potentials and neurotransmitters.
- The synapse is the junction between two neurons where neurotransmitters are released.
- Postsynaptic potentials can be excitatory or inhibitory.
- Neuronal integration involves temporal and spatial summation of postsynaptic potentials.
- Drugs affect synaptic transmission in the nervous system through various sites of action.
- The most complex site of action is on receptors, where drugs can serve as agonists or antagonists.
- Drugs can also affect reuptake or destruction of neurotransmitters, prolonging their presence in the synaptic cleft.
- Placebo effects and the importance of control groups are necessary in studying the effects of drugs on behavior.
- Neurotransmitters have two general effects on postsynaptic membranes: depolarization (EPSP) or hyperpolarization (IPSP).
- The brain's most common neurotransmitters are glutamate (excitatory) and GABA or glycine (inhibitory).
- Acetylcholine is the primary neurotransmitter for muscular movement and is involved in regulating REM sleep, perceptual learning, and memory.
- The monoamines include dopamine, norepinephrine, epinephrine, and serotonin, which are involved in various brain functions and can be affected by drugs.
- Dopamine is involved in addiction and the reward system, but also has other functions in the brain.
- Serotonin is involved in regulating mood, eating, sleep, dreaming, and various bodily functions.
- Serotonin regulates various bodily functions including appetite, sleep, memory, mood, and muscle contraction.
- LSD and MDMA affect serotonin transporters and can have long-term effects on memory.
- Low serotonin levels can lead to depression and anti-depressant medications work by increasing serotonin levels.
- Epinephrine and norepinephrine are hormones and neurotransmitters that play a role in the body's stress response and can be affected by medications used to treat depression.
- Glutamate is the most important excitatory neurotransmitter in the brain and is involved in memory storage.
- GABA is the most important inhibitory neurotransmitter in the brain and is involved in regulating mood and anxiety.
- Benzodiazepines are a category of tranquilizing drugs that enhance the effects of GABA.
- Acetylcholine is the neurotransmitter at the neuromuscular junction and operates in many regions of the brain.
- Glycine is the inhibitory neurotransmitter in the spinal cord.
- Dopamine plays a critical role in the reward system and is implicated in Parkinson's disease and schizophrenia.
