 chemicals released by vesicles in sending neuron  travel across the synapse and bind to receptor sites on receiving neuron 2 TYPES = EXCITATORY = stimulate.

Presentation transcript:

Types of Neurotransmitters & Their Effects on the N.S. Acetylcholine (Ach) (excitatory): the brain’s “memory” & “muscle” chemical. deficiencies: Alzheimer’s dis-ease. excesses: muscle spasms. Dopamine (excitatory): the brain’s “drug addiction” chemical. deficiencies: Parkinson’s dis-ease. excesses: schizophrenia, delusions, hallucinations, addictions.

Types of Neurotransmitters & Their Effects on the N.S. (cont’d.) Norepinephrine (excitatory): the brain’s “caffeine” & “mood” chemical. deficiencies: depression, anorexia. excesses: mania, bulimia, insomnia, ADHD, anxiety, phobias / fears, panic. Serotonin (inhibitory): the brain’s “sleep” & “mood” chemical. deficiencies: insomnia, depression, bulimia,  pain tolerance, PMS, OCD, anxiety, panic attacks, ADHD. excesses: hyper-somnia,  pain tolerance, anorexia.

Types of Neurotransmitters & Their Effects on the N.S. (cont’d.) Endorphins (inhibitory): the brain’s “heroin” & “pain-killer” chemical. 100 times MORE addictive than heroin. deficiencies: insomnia, depression,  pain tolerance, PMS, anxiety. excesses: hyper-somnia,  pain tolerance, mood elevator, “muscle buzz”, “runner’s high”. GABA (inhibitory) -- Gamma Amino Butryic Acid: the brain’s “anti-anxiety” chemical. deficiencies: anxiety dis-orders, depression, phobias, nervousness, panic attacks. excesses: listlessness, serenity, drunkenness.
