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