Brain

• What is the brain's role in the central nervous system?

  It is the control center of the CNS
• What happens when the hypothalamus regulates thirst?

  It signals the body to drink fluids
• If the body temperature rises, how does the hypothalamus respond?

  It activates mechanisms to cool the body
• What does the central nervous system consist of?

  Brain and spinal cord
• What is the primary function of the hypothalamus?

  Maintaining homeostasis
• How can the brain be compared to a ship's captain?

  It makes decisions and coordinates everything
• What are the roles of the brain and the central nervous system?

  • Brain: Controls thought, behavior, and body functions
  • Central Nervous System (CNS): Brain and spinal cord working together
• What role does the pituitary gland play in relation to the hypothalamus?

  It releases hormones as directed by the hypothalamus
• What is homeostasis?

  The body's internal balance
• Which gland is connected to the hypothalamus?

  The pituitary gland
• Why is EEG ideal for capturing brain changes?

  It has high temporal resolution
• How does the hypothalamus contribute to homeostasis?

  By controlling body temperature and regulating thirst
• What is the spatial resolution of EEG?

  Low spatial resolution
• What is the temporal resolution of EEG?

  High temporal resolution
• What does EEG measure in the brain?

  Electrical activity
• What is the spatial resolution of MRI?

  High spatial resolution
• What is the primary function of the thalamus?

  Sensory relay
• How does the hypothalamus manage sleep cycles?

  By regulating hormonal signals related to sleep
• What are the three main parts of the brain besides the lobes?

  Cerebellum, medulla, and pons
• What does MRI scan measure?

  Brain structure
• Why is the hypothalamus considered powerful despite its small size?

  It regulates critical functions for homeostasis
• What are the three main brain imaging methods?

  EEG, MRI, fMRI
• What is neuroplasticity?

  The brain's ability to change and adapt
• What is structural plasticity?

  Physical changes in brain connections
• How does functional plasticity help after a stroke?

  Undamaged areas take over damaged regions' functions
• What types of functions are included in higher processing by the cerebral cortex?

  Conscious thought, language, memory, voluntary actions
• What does fMRI detect in the brain?

  Blood flow changes indirectly
• How does the thalamus function in the brain?

  It routes sensory signals to appropriate brain areas
• What does the cerebral cortex handle?

  Higher processing
• What is the spatial resolution of fMRI?

  High spatial resolution
• What are the functions of the thalamus and cerebral cortex?

  • Thalamus: Sensory relay
  • Cerebral Cortex: Higher thought, voluntary movement
• What are the distinct regions of the brain called?

  Lobes
• What are the main functions of the hypothalamus in homeostasis?

  • Controls body temperature
  • Regulates thirst and hunger
  • Manages sleep cycles
  • Releases hormones via the pituitary gland
• What are the two main types of neuroplasticity?

  • Structural plasticity
  • Functional plasticity
• What is functional plasticity?

  Brain regions adapt their roles
• Can MRI measure brain activity directly?

  No, it cannot measure activity directly
• What functions does the brain control?

  Thought, behavior, and body functions
• What does BOLD response stand for in fMRI?

  Blood Oxygen Level Dependent response
• What is the role of the pons in the brain?

  Relays sensory information and regulates sleep
• What does lateralization refer to in the brain?

  Division of cognitive functions between hemispheres
