Week1 Flashcards
neurotransmitters-neuropeptides- hormones
physiological explanation
routes, brain activity, hormones
ontogenetic explanation
describes how something develops
evolutionary explanation
attention to behavioral similarities
among related species
functional explanation
why ,genetic drift , advantages of traits
graded potentials
hyperpolarizations (inhibitory)(IPSP)
depolarizations (excitatory)(EPSP)
central nervous system
brain
spinal cord
peripheral nervous system
Cranial nerves
spinal nerves
sympathetic¶sempathetic nerves
Glia
Support
Myelination
clearing dead cells& neurotransmitters
protection blood-brain barrier
nurture
Efferent
from A
Motor neurons
Afferent
to B
Sensory neurons
Astrocyctes
Synchronizing(ahtapot gibi)
Purkinje cells are located in
The Cerebellum
Microglia
Immune system
Pruning
Proliferatıon after brain damage
Radial Glia
Migration(stick)
Schwann cell
Myelination
Nutritioning
Oligodendrocyte
ion distribution at rest
iceride muz(K+) disrida tuz(nacl)
Sodium-Potassium pump
keeps the electrical gradient steady( without negatively charged ions)
continuously
2 k+ inside
3 NA+ outside
Otto Lewi
Transferring fluid to another frog
founding: chemicals not electricity
Transporter protein
reuptake of neurotransmitters
retrogade transmitters
postsynaptic neuron releases those to slow further release from presynaptic cell
most important 2 neurotransmitters
excitatory –glutamate
inhibitory– GABA
Ionotropic
controlled by neurotransmitters( neurotransmitter- gated/ligand gated)
Metabotropic
n.transmitters initiating metabolic reactions.
induces more steps
Longer affects
LSD
binds to serotonin receptors
MDMA
releases dopamine/serotonin
Amphetamine/Cocaine
block reuptake of dopamine,serotonin and noreinephrine
Cannabinoids
excite n. feedback receptors on the presynaptic neuron
