Presentation Transcript
  • 85% of Brains Weight
  • Thinking
  • Problem Solve
  • Reason
  • Back of the brain
  • Controls Balance, Movement and Coordination
brain stem
Brain Stem
  • Sits beneath the cerebrum and in front of the cerebellum. 
  • It connects the rest of the brain to the spinal cord.
  • In charge of all the functions your body needs to stay alive. 
  • Controls Involuntary Muscles.
  • Sorts information back and forth.
  • Memory
    • Short Term
    • Long Term
  • Transfers Information
pituitary gland
Pituitary Gland
  • Produce and Release Hormones such as growth, puberty, etc
  • Metabolism
  • Center of the brain
  • Regulates Temperature
gross structures of the brain
Gross Structures of the Brain
      • Medulla
      • Reticular Formation
      • Pons and Cerebellum
  • Controls Sensory Processes
  • Cerbral Hemispheres
  • Each Hemisphere
    • Four Lobes
      • Frontal
      • Thalamus
      • Hypothalamus;
      • and the corpus callosum
cerebral hemispheres
Cerebral Hemispheres
  • Basal Ganglia
    • 3 main functions
    • In current usage, the phrase 'basal ganglia' means: the caudate nucleus, putamen and globus pallidus.
  • Limbic System
    • 4 structures
  • Cerebral Cortex
cortical connections
Cortical Connections
  • Between hemispheres (e.g., corpus callosum)
  • Within a hemisphere, between one lobe and another (association tracks; e.g., arcuate fasciculus)
  • Cortex-Subcortical (e.g., internal capsule)

  • Skull and Meninges
  • Vascular System
  • Ventricular System and CSF
cortical lobes15
Cortical Lobes
  • Occipital: Mediate sight; visual perception; visual knowledge
  • Parietal: tactile sensations; position sense; spatial relations
    • Left: sequential. Logical spatial
    • Right: holistic spatial information
cortical lobes cont
Cortical Lobes (cont.)
  • Temporal: auditory and olfactory abilities; integrating visual perceptions with other sensory info; new learning; emotion; motivation
  • Frontal: motor functions, including speech; executive functions; integration of emotional and motivational states
lateralization of function
Left Hemisphere

Speech and Language

Linear Processing

Well-routinized codes


Contralateral attention

Positive Emotions

Right Hemisphere

Prosody, Humor, Non-literal

Configural Processing (faces)

More adept at novel

Global Percepts

Global attention

Negative Emotions

Lateralization of Function
  • Amnesia
    • Immediate vs. Long-term
    • Remote memory vs. Antereograde memory
    • Implicit vs. Explicit Memory
  • Frontal Lobes: role in retrieval and organization
    • The frontal lobes are the most advanced part of your brain. The frontal lobes are that part of your brain responsible for creativity, logic, intuition, new problem solving, synthesis of ideas, imagination, concepts of time, and planning.
