Neuroscience Flashcards
What is the brain stem in charge of?
Automatic processing
What is the limbic System in charge of?
Emotion and memory
What is the Cerebral Cortex in charge of?
Storage and higher processing
Sensory Neurons
incoming information to the brain (afferent)
Motor Neurons
Exiting the brain (efferent)
Interneurons
in between the exit and enter (central nervous center)
Brain Plasticity
how well your brain is able to connect knew routes
What is a phenotype
characteristics passed on through genes
Genotype
Genetic structure inherited from parents
what order do neeural signals travel along?
dendrite, soma, axon, terminal button
what is synaptic transmission?
When a electrical impulse is changed into a chemical impulse
Neurotransmitters
biochemical substances that are released into synaptic cleft to stimulate or suppress other neurons
Heroin and morphine artificially increase these levels
endorphins
Schizophrenia is linked with..
dopamine
Depression is linked with..
Serotonin
Sympathetic division
associated with fight or flight
