CEREBELLUM

� Below the cerebrum

� Center for coordination of movements and

postural adjustments� Receives and integrates information from

all areas of the body

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

BRAINSTEM

� MEDULLA OBLONGATA

� NUCLEI FOR CN III THROUGH XII

� Locus Ceruleus ± Norepinephrine producing neurons in the

brainstem

 ± Stress, anxiety and impulsive behavior

LIMBIC SYSTEM

� Above the brainstem

� THALAMUS ± Activity,sensation,emotion

� HYPOTHALAMUS ± Temperature regulation, appetite control, impulsivebehavior (anger, rage, excitement), endocrinefunctions, sexual drive

� HIPPOCAMPUS

NEUROTRANSMITTERS

� Neurotransmission

 ± Sending electrochemical messages from to

neuron to neuron

� Dendrites

 ± Projections from the cell body

� Soma/Cell Body

� Axon

 ± Long extended structures

NEUROTRANSMITTERS

� Chemical substances manufactured in the

neuron that aid in transmission of 

information throughout the body

� Excitatory or Inhibitory

Page 14: Psych Reviewer2

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

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

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

NEUROTRANSMITTERS

� ACETYLCHOLINE

 ± found in brain, SC and PNS particularly at the

neuromuscular junction of skeletal muscle

 ± EITHER EXCITATORY OR INHIBITORY

 ± synthesized from CHOLINE

 ± affect sleep wake cycle and signals muscles

to become active

NEUROTRANSMITTERS

� GAMMA-AMINOBUTYRIC ACID

 ± INHIBITORY

 ± modulates other neurotransmitter systemsrather than to provide direct stimulus

 ± increased function: treat anxiety and induce

sleep
