Psyc 122 Flashcards
the word interferes with the color naming when the word and colour do not match
Automaticity theory
reading requires less attention compared to identifying a colour
Selective Attention Process
What are the two types of signals that neurons send?
Excitatory and inhibitory
what is summation
the sum of all incoming signals (Excitatory and inhibitory) determines whether the neuron fires
Oligodendrocytes, Schwann and Astrocytes
3 types of Glial Cells
What is an action potential
change in the voltage inside a cell relative to outside the cell
Saltatory Conduction
node to node conduction of the action potential
Reuptake
the presynaptic cell membrane has neurotransmitter specific proteins that transport neurotransmitters back into the presynaptic cell
Neurotransmitters
chemical messengers that transmit signals across synapses from one neuron to another neuron
Different categories of neurotransmitters
Amino acids, monoamines and peptides
The neuron reaching out to the axon terminal is the same process of neurons connecting to muscle fibers
Receptors
How does neural information processing happen?
The neuron (an excitable cell) receiving through pre-synaptic neurons and dendrites sending action potentials.
Causes cell body to become a little more depolarised and brings it closer to the threshold, increasing action potential.
Excitatory neuron
Hyper-polarisation reduces the chance of action potential
Inhibitory Neuron
1.5
The minimal input required to cause the neuron to fire.
