all areas of the body
8/6/2019 Psych Reviewer2
http://slidepdf.com/reader/full/psych-reviewer2 8/22
BRAINSTEM
� MIDBRAIN ± Connects the pons and cerebellum with the cerebrum
± Respiration, CV functions
± Includes the Reticular Activating System andExtrapyramidal System
± RETICULAR ACTIVATING SYSTEM� Motor activity, sleep consciousness and awareness
± EXTRAPYRAMIDAL SYSTEM� Relayed information about movement and coordination from
brain to spinal nerves
� PONS ± Above medulla, in front of cerebrum, primary motor
pituitary
8/6/2019 Psych Reviewer2
http://slidepdf.com/reader/full/psych-reviewer2 9/22
BRAINSTEM
� MEDULLA OBLONGATA
� NUCLEI FOR CN III THROUGH XII
� Locus Ceruleus ± Norepinephrine producing neurons in the
brainstem
± Stress, anxiety and impulsive behavior

± Long extended structures
8/6/2019 Psych Reviewer2

NEUROTRANSMITTERS
� Chemical substances manufactured in the
neuron that aid in transmission of
information throughout the body
� Excitatory or Inhibitory
8/6/2019 Psych Reviewer2
http://slidepdf.com/reader/full/psych-reviewer2 14/22
NEUROTRANSMITTERS
� DOPAMINE
± primarily in the brainstem
± control of complex movements, motivation, cognition
and regulation of emotional responses ± GENERALLY EXCITATORY
± Synthesized from TYROSINE (amino acid)
± (Schizophrenia, Parkinson¶s and other mov¶t.
disorders) ± Antipsychotics work by blocking this neurotransmitter
8/6/2019 Psych Reviewer2
http://slidepdf.com/reader/full/psych-reviewer2 15/22
NEUROTRANSMITTERS
� NOREPINEPHRINE
± most prevalent in the NS
± primarily in the BRAINSTEM ± changes in attention, learning, memory, sleep
and wakefulness, mood regulation
± Some antidepressants block the reuptake of
this neurotransmitter
8/6/2019 Psych Reviewer2
http://slidepdf.com/reader/full/psych-reviewer2 16/22
NEUROTRANSMITTERS
� EPINEPHRINE ± limited distribution in the brain
± FIGHT OR FLIGHT response in PNS
� SEROTONIN
± derived from TRYPTOPHAN (amino acid) ± MOSTLY INHIBITORY
± control of food intake, sleep and wakefulness, temperatureregulation, pain control, sexual behavior and regulation of emotions
± Plays impt role in anxiety, mood disorders and schizophrenia
± Contributes to DELUSIONS, HALLUCINATIONS ANDWITHDRAWN behavior in Schizophrenia
± Some antidepressants block the reuptake of thisneurotransmitter
8/6/2019 Psych Reviewer2
http://slidepdf.com/reader/full/psych-reviewer2 17/22
NEUROTRANSMITTERS
� ACETYLCHOLINE
± found in brain, SC and PNS particularly at the
neuromuscular junction of skeletal muscle
± EITHER EXCITATORY OR INHIBITORY

� GAMMA-AMINOBUTYRIC ACID
