Cerebral Structure and Function

A comprehensive set of 38 vocabulary flashcards derived from lecture notes regarding cerebral structures and functions for exam preparation.

Diencephalon

The part of the brain consisting of three paired gray matter structures: the thalamus, hypothalamus, and epithalamus.

Thalamus

A structure in the diencephalon that relays sensory and motor signals to the cerebral cortex.

Hypothalamus

The structure in the diencephalon that regulates body temperature, circadian rhythms, and hormone release.

Epithalamus

A region of the diencephalon that includes the pineal gland and regulates sleep-wake cycles.

Basal Nuclei

Also known as basal ganglia; a group of nuclei in the brain that influence muscle movements and regulate intensity of movements.

Cognition

The mental action or process of acquiring knowledge and understanding through thought, experience, and the senses.

Emotion

A complex psychological state that involves physiological arousal, conscious experience, and behavioral expression.

Parkinson's Disease

A neurodegenerative disorder that affects movement, often causing tremors and rigidity, linked to basal nuclei dysfunction.

Huntington's Disease

A genetic disorder that causes the progressive breakdown of nerve cells in the brain, affecting movement and cognition.

Cerebral White Matter

The region of the cerebral hemispheres composed of myelinated axons that facilitates communication between different brain areas.

Myelinated Fibers

Nerve fibers covered with myelin sheath, which increase the speed of signal transmission.

Association Fibers

Horizontal fibers in the cerebral white matter that connect different parts of the same hemisphere.

Commissural Fibers

Horizontal fibers that connect gray matter of the two cerebral hemispheres.

Projection Fibers

Vertical fibers in the cerebral white matter that connect the hemispheres to lower brain structures or the spinal cord.

Internal Capsule

The band of projection fibers that runs between the thalamus and basal nuclei.

Corona Radiata

A fan-like arrangement of projection fibers that radiate out from the internal capsule to the cortex.

Lateralization

The functional specialization of the left and right cerebral hemispheres.

Cerebral Dominance

The tendency of one hemisphere of the brain to control particular functions; typically, language is dominant in the left hemisphere.

Wernicke's Area

A region in the posterior association area involved in understanding written and spoken language.

Multimodal Association Areas

Regions of the cerebral cortex that integrate sensory information from multiple modalities.

Anterior Association Area

Also known as the prefrontal cortex; involved in complex behaviors like judgment, reasoning, and planning.

Posterior Association Area

Involved in recognizing patterns and faces and spatial awareness.

Limbic Association Area

Part of the limbic system that contributes to emotional processing and the formation of memories.

Primary Sensory Cortex

The area of the cortex responsible for processing sensory input from the body.

Primary Olfactory Cortex

The area of the brain responsible for the conscious perception of smell.

Auditory Areas

Regions of the cortex involved in processing auditory information, including pitch, loudness, and location.

Vestibular Cortex

Area responsible for the conscious awareness of balance.

Gustatory Cortex

The region deep in the temporal lobe responsible for the perception of taste.

Visceral Sensory Area

Region responsible for the conscious perception of visceral sensations like hunger and thirst.

Functional Blindness

A condition in which a person cannot see, despite having no physical damage to their eyes.

Mental Disorders

Psychological conditions characterized by alterations in thinking, mood, or behavior.

Social Restraints

Cultural or societal norms that govern behaviors and actions in social contexts.

Clinical Homeostatic Imbalance

A condition where normal functioning is disrupted, often leading to various mental or physical disorders.

Pattern Recognition

The cognitive process of matching information from a stimulus with concepts stored in memory.

Abstract Ideas

Concepts that do not have a physical form but exist as thoughts or qualities.

Spatial Awareness

The ability to be aware of oneself in space and understand one's position relative to other objects.

Emotional Impact

The affective significance of an experience that helps establish and guide memory and emotions.

Schema

A cognitive framework that helps organize and interpret information.
