Unit 3: Biological Psychology
Neurons and Behavior
nervous system cells
Glia
neuronal anatomy
cell body
dendrites
axon
convey information by a combination of electrical and chemical processes; action potential
polarization of axon (charged negatively)--sodium-potassium pump--excites message--depolarization (charge inside cell positive)
synapse
synaptic transmission
synaptic communication
neurotransmitter
The endocrine system
system of glands releases hormones into bloodstream
Drugs and Their Effects
amphetamine
increases release of dopamine and serotonin
cocaine
blocks reuptake of dopamine and serotonin after their release
ritalin
prescribed for ADHD, is a strong, slow-acting stimulant
caffeine
milder and less dangerous drug
cigarettes
nicotine delivery devices, powerfully, addictive stimulant
depressant
alcohol
tranquilizers
barbiturates
benxodiazepines
valium
librium
narcotics
opiates
marijuana
hallucinogens
Peyote
LSD
MDMA/ecstasy
Brain and Behaviour
peripheral nervous system
somatic NS
skin and muscles
autonomic NS
involuntary processes of our internal organs
sympathetic NS
parasympathetic NS
the forebrain
cerebral cortex
occipital lobe
parietal lobe
temporal lobe
hypothalamus, hippocampus, amygdala
frontal lobe
the hindbrain
cerebellum
medulla oblongata and pons
control breathing and heart rate
the spinal cord
measuring brain activity
electroencephalographs and magnetoencephalographs (EEGs and MEGs)
positron emission tomography (PET)
functional magnetic resonance imaging (fMRI)
Genetics and Evolutionary Psychology
genetic principles
chromosomes
homozygous and heterozygous
genes
made of DNA special chemicals that control the production of RNA
RNA control protein production
heritability
sex linked genes
sex limited genes
the relationship between genetic and environment ( nature via nurture)
