I Think Neuron to Something
The minimum amount of time needed before a neuron can fire another action potential
What is refractory period?
The branch of the nervous system that consists of the brain and spinal cord
What is the central nervous system (CNS)?
What is split-brain surgery?
The part of the brain that controls breathing and heartbeat
What is the medulla?
Give an example of how the temporal lobe works.
Answers vary.
The part of the neuron responsible for receiving incoming signals from other neurons
What is a dendrite?
Consists of the sympathetic and parasympathetic nervous system
What is the autonomic nervous system (ANS)
Give 3 types of brain scans that show functioning.
EEG, MEG, PET, fMRI
The part of the brain responsible for coordinating voluntary movement and balance
What is the cerebellum?
The (somato)sensory cortex is located in this lobe. This lobe assists with sensory processing and reasoning.
What is the parietal lobe?
Where neurotransmitters are released from???
What are terminal branches?
The division of the nervous system that allows us to feel the world and move around in it
What is the somatic NS?
Hindbrain structure involved in sleep and arousal
What is the pons?
Limbic system structure responsible for learning fear and other basic emotional responses
What is the amygdala?
Wernicke's area is located in this lobe
What is the LEFT temporal lobe?
Explain what the role of the soma and myelin sheath are.
Soma - life support center
Myelin sheath - encases axon; increases transmission speed
Neurons/nerves that carry sensory information inward, toward the central nervous system
What are afferent/sensory neurons?
The part of the brain that determines which hormones need to be released through the endocrine system
What is the hypothalamus?
If this part of the brain is significantly damaged, a person would likely fall into a deep coma and not wake up
What is the reticular formation?
Broca's area is located in this lobe
Left Frontal
Explain when a neuron is polarized and depolarized.
Polarized - resting potential
Depolarized - action potential
Activation of this branch of our nervous system would result in slowed heart rate and increased digestion (be specific)
What is the parasympathetic NS?
Give 3 types of brain scans that show structure.
CT, MRI, fMRI
The part of the brain that acts as our sensory switchboard, routing all sensory messages except smell
What is the thalamus?
Visual information from the right side of each eye is sent to this lobe
What is the occipital lobe?
