Behavioral Neuro
The brain and its connections are not static but can change physically and/or functionally in response to experience. This is called_______.
What is neuroplasticity or plasticity?
The most anterior lobe of the brain.
What is frontal lobe?
The kind of electrical change that an EPSP makes on the membrane potential.
What is depolarization or 'making it more positive'?
The kind of chemical/substance that has the ability to bind to receptors in your NS but is not created by your body.
What is an exogenous ligand?
This produces CSF.
What is choroid plexus?
What is: behavioral/cognitive level, organ level, neural systems level, brain region level, cellular level, circuit level, synaptic level, molecular level?
Neurons are independent entities, not continuous with one another and they communicate via synapses.
Two significant things that affect conduction velocity.
What is axon diameter and myelination?
This neurotransmitter system synthesizes a chemical that works to regulate arousal, fight/flight, mood, and sexual behavior.
What is the noradrenergic system?
Distribution of calcium ions when neuron is at rest.
What is high outside compared to inside?
Definition of phrenology.
What is cerebral cortex has separate functional areas AND by observing shape of skull you can make inferences about behavioral faculties?
Division of the nervous system that would be highly active while I'm resting and digesting.
What is the sympathetic ns?
What is towards the intracellular space/inside the neuron?
Transporters on the presynaptic membrane do the job of_________.
What is reuptake?
Characteristic of the 'tails' that make up the phospholipid bilayer of cell membranes in the nervous system.
What is hydrophobic or fatty substance that does not mix with water?
Belief/idea that the mind is only and simply a result of the brain and these two are not separate entities.
What is monism?
If I make a midsagittal cut, the function of the lobe that is superior anterior to the occipital lobe.
What is any function of the parietal lobe (sensory processing and association cortex, etc.)
Explain the difference between graded potential, action potential, resting potential, and membrane potential.
What is: a)graded: local, degrades with distance, size is dependent on stimulus b)action: all or none, regenerates at same magnitude c) resting potential: voltage when neuron is at rest d) membrane potential: voltage at any given time?
Type of channel and ion it is specific to responsible for initiating exocytosis at the terminal/button.
What is voltage-gated calcium channels?
One way in which drugs alter postsynaptic events.
What is: a) effects on receptors--blocking them, activating them or b)effects on cellular processes--up/downregulation of receptors, changing gene expression?
Example of a somatic intervention (stating the IV and DV).
What is: anything that has an IV which manipulates the body and a DV which is measurable?
Description of the structures and functions of the ventricular system.
What is ventricles, csf, choroid plexus and functions are to act as shock absorber, provide exchange medium between blood and brain?
The chronological states that voltage-gated Na+ channels undergo when neuron is at rest through the action potential and back to rest.
What is: at rest they are closed, at threshold they open (activate), at peak or later they start to close and cannot open (inactive), then they remain close but can open(deactive) then they go back to just being closed and ready to be activated again once neuron is at rest.?
Cannabis exerts its effects because we have receptors that have a binding site for THC. This class of chemicals is the endogenous analog of THC.
What are endocannabinoids?
Difference between affinity vs efficacy.
What is affinity is propensity of ligands to bind to receptors (strength of binding); efficacy is ability of ligand to activate a receptor (or how likely it is to open it)?
