Psychophysiological methods in neuroscience Flashcards
The signal typically measured in fMRI that results from changes in the ratio of oxygenated
hemoglobin to deoxygenated hemoglobin in the blood.
Blood oxygen level dependent
The part of the nervous system that consists of the brain and spinal cord.
Central nervous system
Hemoglobin not carrying oxygen.
Deoxygenated hemoglobin
A change in a cell’s membrane potential, making the inside of the cell more positive and
increasing the chance of an action potential.
Depolarization
A change in a cell’s membrane potential, making the inside of the cell more negative and
decreasing the chance of an action potential.
Hyperpolarization
The oxygen-carrying portion of a red blood cell
Hemoglobin
A procedure that involves the skin being broken or an instrument or chemical being introduced
into a body cavity.
Invasive procedure
Abnormalities in the tissue of an organism usually caused by disease or trauma
Lesions
The ability of synapses and neural pathways to change over time and adapt to changes in
neural process, behavior, or environment.
Neural plasticity
A research method that deals with the structure or function of the nervous system and brain.
Neuroscience methods
A procedure that does not require the insertion of an instrument or chemical through the
skin or into a body cavity
Noninvasive procedure
One of the two major divisions of the autonomic nervous system, responsible for stimulation
of “rest and digest” activities.
Parasympathetic nervous system
Hemoglobin carrying oxygen
Oxygenated hemoglobin
The part of the nervous system that is outside the brain and spinal cord.
Peripheral nervous system
A particle having the same mass and numerically equal but positive charge as an electron.
Positron
