the science of how the mind is organized to produce intelligent thought and how it is realized in the brain.
a field of computer science that attempts to develop programs that will enable machines to display intelligent behavior.
the position that knowledge is acquired through experience in the world.
The position that children are born with a great deal of innate knowledge.
A methodology much practiced at the turn of the 20th century in Germany that attempted to analyze thought into it's components through self analysis.
the theory that psychology should be concerned only with behavior and should not refer to mental constructs underlying behavior.
an approach to psychology that emphasizes principles or organization that result in holistic properties of the brain that go beyond the activity of the parts.
the study of the structure of language
an analysis of human cognition into a set of steps in which abstract information is processed.
an experimental procedure in which participants are presented with a memory set consisting of a few items and must decide whether various probe items are in the memory set.
the study of the neural basis of cognition
the cell in the nervous system responsible for information processing. Neurons accumulate and transmit electrical activity.
the branching part of a neuron that receives synapses from the axons of other neurons.
the location at which the axon of one neuron almost makes contact with another neuron.
a chemical that crosses the synapse from the axon of one neuron and alters the electric potential of the membrane of another neuron.
a synapse in which the neurotransmitters decrease the potential difference across the membrane of the neuron.
a synapse in which the neurotransmitters increase the potential difference across the membrane of the neuron.
the sudden change in electric potential that travels down the axon of a neuron.
Rate of Firing
the rate at which nerve impulses are generated along axons.
the region at the back of the cerebral cortex that controls vision.
an inward fold of the brain that contrasts with the gyrus.
an outward fold on the brain
the region at the top of the cerebral cortex concerned with attention and higher level sensory functions.
the region at the side of the cerebral cortex that contains the primary auditory areas and controls the recognition of objects.
the region at the front of the cerebral cortex that includes the motor cortex and the prefrontal cortex.
the region at the front of the frontal cortex that controls planning and other higher level cognition.
a structure within the temporal lobe that plays a critical role in the formation of permanent memories.
subcortical nuclei that play a critical role in control of motor movement and cognition.
a broad band of fibers that enables communication between the left and the right hemispheres of the brain
Split Brained Patients
a patient who has had surgery to sever the corpus callosum, which connects left and right hemisphere.
a region in the left frontal cortex that is important for processing language, particularly syntax in speech.
a region of the left temporal lobe important to language, particularly the semantic content of speech.
an impairment of speech that results from a brain injury
a principle of neural organization in which adjacent areas of the cortex process information from adjacent parts of the sensory field.
measurement of electrical activity of the brain measured by electrodes on the scalp
Event Related Potential (ERP)
measurement of changes in electrical activity at the scalp in response to an external event.
measurement of magnetic fields produced by electrical activity in the brain.
Positron Emission Topography (PET)
a method for measuring metabolic activity in different regions of the brain with the use of a radioactive tracer
Functional Magnetic Resonance Imaging (fMRI)
a method for determining metabolic activity by measuring the magnetic field produced by the iron in oxygenated blood.
the increased flow of oxygenated blood to a region of the brain that has greater activity this is the basis of fMRI brain imaging.
Trasncranial Magnetic Stimulaiton (TMS)
a magnetic field is applied to the surface of the head to disrupt the neural processing in that region of the brain.
Blood Oxygen Level Dependent (BOLD) Response
a measure obtained in fMRI studies of the amount of oxygen in the blood.
