Tenencephalon Flashcards
Major Sulci of Cerebral Cortex
- Cerebral Sulcus
- Lateral Sulcus
- Parietoccipital Sulcus
- Intraparietal Sulcus
- Cingulate Sulcus
What does the Central Sulcus Separate?
Frontal and Parietal Lobes
What does the Lateral Sulcus Separate?
Frontal and Parietal Lobe from Temporal Lobe
What does the Parietoccipital Sulcus Separate?
Parietal from Occipital
What does the Intraparietal Sulcus Separate?
Divides Inferior and Superior Parietal Lobes
What does the Cingulate Sulcus Separate?
Cingulate gyrus from overlying cortical areas
Key Functions of Frontal Lobe
Motor: Planning and Execution
- Primary Motor Cortex
- Premotor Cortex
- Supplementary Motor Area
- Frontal Eye Fields (Motor Mechanisms for eye movement)
- Brocas Area
Mental: Executive Functions
- Social Cognition and Emotional Regulation
Key Functions of Occipital Lobe
Visual Processing
Key Functions of Temporal Lobe
- Basic Auditory processing
- Language comprehension: Wernickes Area
- Ventral Stream pf Vision: Important for object identification and face recognition (What and who stream)
- Memory and Social Cognition
Key Functions of Parietal Lobe
- Sensory Perception
- Language Comprehension - Wernickes Area
- Dorsal Stream of vision: location of objects with reference to space and body (Where and How stream)
- Visuospatial processing, episodic memory retrieval, and self processing operations
Key Gyri of Frontal Lobe
Precentral and Anterior Paracentral Gyrus: Primary Motor Control
- 3 Horizontal Gyri: Superior, middle, and inferior Frontal Gyrus
- 2 Gyri at base of frontal lobe (Gyrus Rectus and Orbital Gyrus)
Which Frontal Gyrus includes Brocas Area?
Inferior Frontal Gyrus
Key Gyri of Parietal Lobe
- Postcentral Gyrus and Paracentral Gyrus: Somatorsensory Cortex
- Superior Parietal Lobule
- Inferior Parietal Lobule: Supramarginal and Argular Gyrus
Key Gyri of Temporal Lobe
- Transverse temporal gyrus: Primary Auditory cortex
4 Horizontal Gyri:
- Superior Temporal Gyrus
- Middle Temporal Gyrus
- Inferior Temporal Gyrus
- Occipital Temporal Gyrus
