Study Guide for Neuroplasticity

Biological Psychology

The scientific study of links between biological (genetic, neural, hormonal) and psychological processes.

Neuroplasticity

The brain's ability to change and adapt as a result of experience.

Neuroplasticity

The brain's ability to change and adapt as a result of experience.

Lesion

Tissue destruction; a brain lesion is a naturally or experimentally caused destruction of brain tissue.

EEG (Electroencephalogram)

A test used to evaluate the electrical activity in the brain.

CAT scan (Computerized Axial Tomography)

A sophisticated x-ray of the brain that provides a 3D picture to locate tumors.

MRI (Magnetic Resonance Imaging)

A method used to study brain functions and structures without surgery.

PET (Positron Emission Tomography)

Produces a visual display of brain activity by tracking radioactive glucose.

Hindbrain

The part of the brain that controls basic biological functions necessary for survival.

Cerebellum

The part of the brain responsible for processing sensory input and coordinating movement.

Limbic System

The emotional brain, involved in emotions, drives, and memory.

Corpus Callosum

The band of nerve fibers connecting the two hemispheres of the brain.

Neurogenesis

The formation of new neurons.

Split brain

A condition resulting from surgery that isolates the brain's two hemispheres by cutting the corpus callosum.

Frontal Lobe

Part of the brain responsible for complex associations, speaking, and judgment.

Parietal Lobe

Area of the brain that holds the sensory cortex for incoming messages.

Occipital Lobe

The part of the brain where vision is processed.

Temporal Lobe

Part of the brain responsible for auditory processing and language.

Motor Cortex

Responsible for outgoing messages from the brain to control voluntary movements.

Somatosensory Cortex

Processes body touch and movement sensations.

Association Areas

Areas involved in higher mental functions such as learning, remembering, and thinking.

Reticular Activating System (RAS)

Regulates arousal level and connects parts of the brain.

Thalamus

Connects sensory apparatus to higher brain and directs messages accordingly.
