Study Notes
Cerebral Cortex
- Receives inputs from the thalamus
- Contains approximately 16-20 billion neurons
Function of Cerebral Cortex
- Primary function is to integrate sensory information and facilitate thought, perception, and voluntary movement
Motor Cortex
- Responsible for regulating voluntary movement
- Has a direct pathway to anterior motor neurons for skilled movements, such as finger movements
Language
- Wernicke's area is responsible for speech comprehension
Inter-Hemispheric Connection
- The corpus callosum connects the two hemispheres of the brain
Multimodal Processing
- The inferior parietal lobe is important for understanding and interpreting music, nonverbal visual experiences, and body language
Motor Control
- The premotor cortex is responsible for hand movements and is affected in motor apraxia
Motor Signal Transmission
- The corticospinal tract is responsible for transmitting signals from the motor cortex to the muscles
Respiratory Control
- The pons region of the brain stem provides control of respiration
Vestibular System
- The vestibular apparatus is located in the inner ear
Developmental Disorder
- Anencephaly is characterized by the absence of brain structures above the mesencephalic region
