What is cognitive neuroscience
Localization of function, neural representations of information, and information flow in the brain
What are neurons
Basic building blocks of the brain and nervous system
Parts/structure of neuron
Dendrite, cell body, axon
What do dendrites do
Recieve messages
What does the cell body (soma) do
Keeps the cell alive
What does the axon do
Sends messages
Where does an axon end
In the axon terminal
What may an axon have
Myelin sheath
What is resting potential
Neuron at rest
What is action potential
Change in electrical charge of a neuron
What are neurotransmitters
Chemicals released by one neuron to transmit information to other neurons
What function does Acetylcholine (neurotransmitter) serve
Memory
What function does norepinephrine (neurotrasmitter) serve
Memory retrival, attention, and alertness
What function does dopamine (neurotrasmitter) serve
Motivation and impulse control
What function does serotonin (neurotransmitter) serve
Attention, mood, and eating behavior
What function does glutamate serve
Learning and memory
What do glial cells do/not do
Don’t transmit information but support the transmission
What funtion do astrocytes serve
Immune function, provide energy, information processing
What function do oligodendrocytes serve
Create myelin
What function(s) does the basel ganglia serve
Controls, regulates, and coordinates voluntary movements as well as learning
What functions does the limbic system serve
Deals with emotion, memory, and motivation, has the amygdala- fear and anger zone, has the hippocampus- necessary for memory generation
What funtion does the thalamus serve
Sensory relay, all sense information goes through except smell
What function does the hypothalamus serve
Regulates the four f’s of survival
What is specificity coding
Specialized firing of a neuron for one stimulus
