Involved in many aspects of personality

12

Define Neurotransmitter

Chemicals that transmit messages from neuron to neuron

13

Common Excitatory Neurotransmitters

Acetylcholine (Ach)
Norepinephrine (NE)

14

Common Inhibitory Neurotransmitters

Dopamine
Serotonin
GABA

15

Normal Functions of Acetylcholine

Muscle action
Learning
Memory

16

Malfunction of Acetylcholine (not enough)

Dementia
Alzheimer's

17

Normal Function of Dopamine

Movement
Learning
Attention
Emotion
Motivation
Mood control
Reward center

18

Malfunction of Dopamine

Too much: schizophrenia, hallucinations, delusions
Too little: depression, Parkinson's

19

Normal Function of Serotonin

Emotion
Motivation
Mood
Hunger
Sleep
General level of arousal

20

Malfunction of Serotonin

Not enough: depression
Too much: mania, impulsive or rash decisions

21

Normal Function of Norepinephrine

Alertness
Arousal

22

Malfunction of Norepinephrine

Not enough: depression

23

Normal Functions of GABA

Blocks nerve impulses
Dial down neuron activity

24

Not enough GABA

Lead to seizures, tremors, or insomnia

25

Too much Glutamate

Over stimulate the brain & could lead to seizures

26

What disorder is caused by an excess of dopamine?

Schizophrenia

27

What other neurotransmitters are associated with schizophrenia?
