Telencephalon I: Cortex Flashcards
What structure entails high-level processes?
cortex
Give examples of high-level processes:
- Sensory integration
- Motor control
- Learning
- Memory formation, storage, and retrieval
- Emotional expression
- Personality
- Decision making
- Language
What structure is the outermost and largest region of the brain?
cerebrum
The cerebrum is formed by three groups of structures:
- cortex
- basal ganglia/nuclei
- limbic system
What sections comprise the forebrain?
- telencephalon
- diencephalon
What section is in the midbrain?
- mesencephalon
What sections comprise the hindbrain?
- metencephalon
- myelencephalon
What is highly folded, outer layer of gray and white matter of the cerebrum?
cerebral cortex
What plays a key role in attention, perception, awareness, thought, long-term memory, cognition, language, emotion control, and consciousness?
cerebral cortex
The cortex is divided into how many lobes?
5
What are the lobes of the cortex called?
- frontal
- parietal
- occipital
- temporal
- insular
What cortex is in the occipital lobe?
visual
(primary visual cortex and visual association area)
What cortex is in the parietal lobe?
sensory cortex
(somatic sensory association area)
What structure divides the parietal and frontal lobe?
central sulcus
What cortices are in the frontal lobe?
- motor cortex
(somatic motor association area) - gustatory
- olfactory
What cortex is in the temporal lobe?
auditory cortex
(primary auditory cortex and auditory association area)
The cortex is divided into three functional areas:
- motor cortex
- sensory cortex
- association cortex
TRUE or FALSE: The cortex is somatotopically organized.
TRUE
The motor region is a cortical region that control ___________ movements. It is divided into two parts:
voluntary
- premotor motor cortex
- primary motor cortex
What structure receives inputs from the basal ganglia and projects directly to the primary motor cortex to produce elaborate movements.
premotor cortex
The premotor cortex receives inputs from the ______________________.
basal ganglia
What executes voluntary movements?
primary motor cortex
The primary motor cortex receives inputs from the ____________________, _______________________ and ___________________.
primary somatosensory cortex, the thalamus, and premotor areas
The primary motor cortex projects to the _______________.
Thalamus
Different regions of the cortex process information from four senses, via the ______________ .
thalamus
What cortex involves sensory input from the skin and joints?
Somatosensory cortex
What cortex involves auditive and vestibular information from CN VIII?
Auditory and vestibular cortex
What cortex involves taste from CN VII, IX, X?
Gustatory cortex
What cortex involves visual input from CN II?
visual cortex
________________ information goes directly from CN I to the __________ cortex, bypassing the thalamus.
Olfactory
What makes associations between different types of sensory information?
association cortex
The ____________________ ________________ cortex involves attention, thinking, planning, problem-solving, emotional control, personality.
Anterior association cortex
The _______________________ __________ cortex involves integrated perception, processing of visual language, and naming objects.
Posterior association cortex
The __________________ _______________ cortex associates sensory input with limbic areas, memory and, cognition, language processing.
Limbic association cortex
