Biological Approach Flashcards
MRI scans
produce a 3-D figure of the brain through a magntic fields and pulses of radio wave energy
fMRI scans
a technique that measures tiny metabolic changes in the active parts of the brain
Localization of functions
this refers to the theory that different functions such as emotions, thought, and behavior are located in different parts of the brain
The (posterior) Hippocampus
in charge for spacial memory in the brain
neuroplasticity
the ability of the neural networks to be altered and accustomed to outside factors
neural pruning
the removal of neural pathways that are no longer used or needed
neurogenesis
the ability of the brain to form new neuron connections
what do dendrides do?
a part of the neuron that collects impulses from other cells
what do axons do?
transmit the impulse (the electrical impulse)
what does the myelin shiled do?
the myelin sheath allows for the speeding up of the passing of the neural impulse
what do the terminal branches of the exon do?
transmit the impulse to other cells
excitatory postsynaptic potential
increases the possibility of producing an action potential in the receiving cell
inhibitory postsynaptic potential
decreases the probability for producing an action potential in the receiving cell
neurotransmitters vs electrical impulses
neurotransmitters are chemicals that transmit the electrical impulses between cells
agonists
increase the effect of neurotransmitters
