Brain Lobes and Functions

Flashcards covering the various lobes of the brain and associated functions.

Temporal Lobe

Important for auditory processing, recognizing, and naming specific objects.

Agnosia

Aware of an object but can't name it; loss of connection between recognition and applying a name.

Prosopagnosia

The inability to identify faces.

Frontal Lobe

Separated from the parietal lobe by the central sulcus. Important in personality, planning, and social awareness.

Primary Motor Cortex

Area on the frontal lobe side of the central sulcus that maps out skeletal muscle groups, controlling motor function.

Parietal Lobe

Contains the primary somatosensory cortex, responsible for the feeling of touch and spatial processing.

Primary Somatosensory Cortex

Strip of cerebrum on the parietal lobe side that exists before the central sulcus. Body map relating to touching sensation.

Contralateral Neglect

Damage to the right parietal lobe leads to inability to process sensory information from the left side of the body.

Occipital Lobe

Receives and processes information primarily associated with the visual system.

PET Scanning

Positron Emission Tomography, involves injecting a radioactive substance to label high energy consumption areas of the brain.

Wernicke's Area

Area of the brain associated with interpreting language.

Broca's Area

Area of the brain associated with producing language.

Aphasia

Condition resulting from damage to language processing centers in the brain.

Wernicke's Aphasia

Inability to understand visual or spoken communication due to damage in Wernicke's area.

Broca's Aphasia

Inability to produce sensible spoken or written language due to damage in Broca's area.
