BEHAVIORALNEUROSCIENCE
Neuroscience- scientificstudy of the nervoussystem
Neurons- carriesneurotransmittersthatispassedonto the otherneurons,muscles,heart,brain
- It has 2 specializedextensions;
o One isfor receivingelectricsignals
o The other,longerextension,isfortransmittingelectricsignals.
Parts ofthe neurons
1. Nucleus- powerhouse of the neuron;providefoodandenergy
2. Cell Body(or Soma)- providesfuel,manufactureschemicalsandmaintainsthe entire neuron
workingtogether.
3. Dendrites- receive signalsfromotherneurons,musclesandsense organs
4. Axon- carriessignalsawayfromthe cell bodytoneighbouringneurons,organsandmuscles
5. MyelinSheath- preventsinterference fromelectricsignalsgeneratedinadjacentaxons.
6. End Bulbs (or Terminal Bulbs)- storesneurotransmittersusedtocommunicate with
neighbouringcells
7. Synapse- isan infinitelysmallspace( 20-30
bilionthsof ameter) thatexistbetweenanendbulb
and itsadjacentbodyorgan (heart),muscles, (head)or
cell body.Thisis wherethe neurotransmitterscrossto
information.
Neurotransmitters- chemicals made byneuronsandthenusedforcommunicationbetweenneurons
duringthe performance of mental orphysical activities.
Neurotransmitters- theyplayarole inthe waywe behave,learn,feel,andsleep.Andsome playarole in
mental illness.
End bulbs
Neurotransmitters
1. Acetylcholine- involvedininvoluntarymovements,learning,memory and sleep
a. Too much will leadto depression
b. Too little will leadto dementia
2. Dopamine- correlatedwith movement,attention,learning
a. Too much will leadto schizophrenia
b. Too little will leadto depression,muscularrigidity& tremors foundin Parkinsons’
disease
3. Norepinephrine- associatedwith alertness,eating
a. Too little will leadto depression
b. Too much will leadto schizophrenia
4. Epinephrine- involvedin energy,glucose,metabolism
a. Too little will leadto depression
5. Serotonin- playa role in mood,sleep,appetite,impulsiveand aggression behaviour
a. Too little will leadto depression,anxiety,OCD
b. Some anti-depressantsmedicationincreasethe availabilityof Serotonin;usedtotreat
depression,anxiety
c. Happy neuron
6. GABA (Gamma-AminoButyricAcid)- inhibits excitation and anxiety
a. Too little will leadtoanxiety,anxietydisorder
b. Some anti-anxietymedicationincreasethe availabilityof GABA;usedtotreatanxiety
7. Endorphins- pain relief and feelingsof pleasure
BEHAVIORAL GENETICS
Studyof howinheritedgenescontribute toabnormal behaviour
Genotype- total geneticmakeup,composedof genes
Genotype- example:DNA structure
Phenotype-observablebehaviouralprofile
Phenotype-example:eye color
4 Methodsof Behavioral Genetics
1. FamilyMethod (indexcases/probards)- studyingafamilymember,usuallythe one whoseeks
medical attention. Thisway they can tracethe genetic disorderfound in their family.
a. Parents; sister-brother- share50% genes
b. Grandparents;aunts-uncles- share25% genes
c. Great-grandparents;greataunts-uncles- share12.5% genes
d. General populationshare very fewgenes
2. Twin Method(concordance)- presence of the same traitintwins
Monozygotic(identical twins) Dizygotic (fraternal twins)
 1 eggcell isfertilizedby1 sperm
 There isa divisionofthe zygote
 Theyalwayshave the same gender
 They share 100% of genes
 2 different egg cells are fertilized by 2 different
sperm
 There are two separate zygotes
 They may be same or of different gender
 They share 50% of genes
3. AdopteesMethod(controlsenvironment)-evaluate geneticandenvironmental influence on
phenotype
4. Linkage Analysis(future directions)- serve asa wayof gene testing
