PSU Psych 260 Exam 1

neuroscience - ANSthe scientific study of the brain and nervous system in health and disease

biological psychology - ANSstudy of the biological foundations of behavior, emotions, and
mental processes

molecular neuroscientist - ANSattempts to understand the chemicals that build the system and
make neural functioning possible

cellular neuroscientist - ANSoutlines the structure, physiological properties, and functions of
single cells found within the nervous system

synaptic neuroscience - ANSexamines the strength and flexibility of neural connections

cognitive neuroscience - ANSstudy of the biological correlates of information processing,
learning and memory, decision making, and reasoning

social neuroscience - ANSexplores the interactions between the nervous system and our
human social environment and behavior

mind-body dualism - ANSRene Descarte's idea that the body is mechanistic while the mind is
separate and nonphysical; can't be studied through the natural sciences

monism - ANSphilosophical idea that the mind is the product of activity in the brain and,
therefore, can be scientifically studied

John Hughlings Jackson - ANSfounder of modern neuroscience; nervous system is organized in
a hierarchy with simpler processes carried out by lower levels and more sophisticated
processing carried out by higher levels

histological - ANSmicroscopic methods that provide means for observing the structure,
organization, and connections of individual cells and tissues

microtome - ANSa device used to make very thin slices of tissue for histology

Golgi stain - ANSallows for detailed structural analysis of a small number of single cells (single
neurons)

Nissl stain - ANSallows for identifying clusters of cell bodies within a sample of tissue

, myelin stain - ANSallows for tracking pathways that carry information from one part of the brain
to another by staining the insulating material that covers many nerve fibers; traces neural
pathways

horseradish peroxidase - ANSa stain used to trace axon pathways from their terminals to points
of origin

computerized tomography (CT) - ANScomputers are used to enhance X-ray images to image
previously unseen anatomical structures, such as the brain

Positron Emission Tomography (PET) - ANSimaging that observes the localization of brain
activity by detecting radiation released by radioactive atoms that are decaying or breaking up

magnetic resonance imaging (MRI) - ANSimaging that uses powerful magnets to align hydrogen
atoms within a magnetic field to provide very high resolution structural images

functional magnetic resonance imaging (fMRI) - ANSimaging that allows us to correlate brain
activity with the presentation of a stimulus, emotional state, or task performance by tracking the
variations of blood flow to a particular area of the brain

Diffusion Tensor Imaging (DTI) - ANSimaging that maps connectivity in the brain by tracking the
movement of water in the fiber pathways of the nervous system BUT does not tell us about the
direction of flow

Electroencephalogram (EEG) - ANSrecording of the brain's electrical activity

event-related potential (ERP) - ANSform of EEG that allows for the correlation of timing of
activity of cortical neurons with stimuli presented to the participant

Magnetoencephalography (MEG) - ANSform of EEG that allows researchers to record the
brain's magnetic activity

repeated transcranial magnetic stimulation (rTMS) - ANStechnique for stimulating the cortex at
regular intervals by applying magnetic pulses delivered through a single coil of wire encased in
plastic that is placed on the scalp

optogenetics - ANSthe genetic insertion of molecules into specific neurons in the brain resulting
in the ability of neural function to be modified by light

ablation - ANSsurgical removal of tissue

concordance rate - ANSstatistical probability that two cases will agree, usually involving twin
studies
