Parts fo the Brain

The Brainstem

• Oldest and innermost region of the brain

• Starts where the spinal cord swells as it enters the skull

• Responsible for automatic survival functions

Medulla

• Base of the Brainstem controls heartbeats and breathing

Thalamus

• A pair of egg-shaped structures

• The brain’s sensory control center

• Receives information form all the sense except small and routes that informations to the higher brain Regan’s that deal with

  • Seeing

  • Hearing

  • Tasting

  • Touching

Reticular Formation

• A neurons network

• Form the spinal cord to the thalamus

• Controls waking and sleeping

Cerebellum

• Called the “little brain”

• Enables nonverbal learning and skill memory

• Coordinating movement output and balance, and enabling nonverbal learning and memory

• Is at the back of the head, below the temporal and occipital lobes and above the brainstem

Limbic System

• Is the amygdala, hypothalamus and hippocampus

Amygdala

• A Lima bean sized neural counts ion that is linked to emotion

Hypothalamus

• A neural structure lying below the thalamus

• Directs several maintenance activities

• Helps govern that endocrine system and is linked to emotion and reward

Hippocampus

• Is a sea horse-shaped

• Processes conscious, explicit memories and degrees in size function as we age

Frontal Lobes

• Lying behind the forehand

  • Involved in speaking and muscle moment and in making plans and judgment

Parietal Lobes

• Lying at the top of the head

  • Used for sensory input touch and body

Occipital Lobes

• On the back of the head

  • Is for visual information

Temporal Lobes

• Is above the ears

  • Used for memories storing and retrieving them

Motor Cortex

• In the frontal lobe in front of the central sulcus

  • Used to move the body around

Sensory Cortex or Somatosensory cortex

• Is in the parietal lobe

  • Specialized in receiving information form the skin senses like touch and temperature and movement of body parts

Broca’s Area

• Is in the frontal lobe of the left hemisphere of the the brain

  • Used for language production, coordinations speech movements, and understanding word meanings

Wernicke’s Area

• Is in t posterior part of the superior temporal gyrus

  • Is used to understand t languages and is a part of a larger network
