Physiological Psych Flashcards
Heritability
Likelihood of jeans getting passed to the next generation
Epigenetic’s
Genes that turn on or off based on the environment
Central nervous system
Exists to interact with environment
Centers all over body
CMS make sense of input and output senses
Brain and spinal cord
Soma
Creates energy neurotransmitters made here
Sensory neurons
Sensory systems that have specialized dendrites, photons, pressures
Axon Hillock
Sodium snakes in and change his balance of about 10 MV. Sodium ask as trigger to open gates
Depolarization
-70mv to -60 mv
Hyperpolarization
I am gates open up, sodium goes in, up to 40 MV
Action potential
Process of deep polarization and hyperpolarization
Glia cells
Microglia – CNc– Act as immune system for bran new paragraph
astrocytes– Structural support – create blood brain barrier
Oligodendrocytes – create myelin sheath! Schwann cells
Gray matter
So bodies\nuclei – cortex
White matter
Mylinated axons\tracts
Occipital lobe
Processes visual information
Temporal lobe
Processes auditory, verbal
Frontal lobe
Executive functions
Parietal lobe
Visual spatial organization
Cerebellum
Involved with motor functions
Pons
Sensory processing and translating
Proliferation
Creation of neurons until age 3
Neurogenesis
Creation of new neurons
Golgi stain
While neuron
Nissan stain
Cell bodies -some , grey matter
Markers
Molecules that attached to other molecules the seller uses
Structural imagine
Mri
Ct/cat
Functional imaging
Direct
– E.g.
– MEG
Indirect
– PET attaches to glucose
SPECT attaches to oxygen
FMRI
Antagonist
Any substance that decreases the effectiveness of neurotransmitters
Agonist
Any substance that enhances the effectiveness of a nerd transmitters
Isotropic
Short term effect
Met a bow tropic
Long term effect
