Presentation Transcript

  1. Chapter 2 G:The Cerebral Cortex A.P. Psychology

  2. Do-Now(In Journal) • Using your book or notes, Identifythe parts of the older brain structures that are responsible for the following functions: • Heartbeat: • All senses except for smell: • Feeling angry: • Memories of freshman year: • Sexual arousal: • Body movement: • Balance: • Reaching for food (survival): • Body temperature:

  3. Structure of the Cerebral Cortex • Cerebral Cortex: • Intricate fabric of interconnected neural cells covering the cerebral hemispheres • The body’s ultimate control and information-processing center • Glial Cells (Glia): • Cells in the nervous system that support, nourish, and protect neurons

  4. Structure of the Cerebral Cortex • Frontal Lobes: • Located behind the forehead • Functions: • Speaking • Muscle Movements • Judgments • Parietal Lobes: • Located at the top/rear of the head • Functions: • Sensory Input (Touch/Body position)

  5. Structure of the Cerebral Cortex • Occipital Lobes • Located at the back of the head • Includes Visual Cortex • Functions: • Receives information from visual fields • Temporal Lobes • Located roughly above the ears • Includes Auditory Cortex • Functions: • Receiving information primarily from the opposite ear

  6. Structure of the Cerebral Cortex

  7. The Visual and Auditory Cortex

  8. The Visual and Auditory Cortex Which lobe is responsible for interpreting visual information? Which lobe is responsible for interpreting auditory information?

  9. f.M.R.I.:Stimulation of Visual Cortex

  10. Functions of the Cerebral Cortex • Motor Cortex: • Located at rear of frontal lobes • Controls voluntary movements (Output) • Sensory Cortex: • Located at front of parietal lobes • Registers and processes body touch and movement sensations (Input) • Association Areas: • Areas of the cerebral cortex that are not involved with primary motor/sensory functions • Involved in higher mental functions: • Learning • Remembering • Thinking • Speaking

  11. Functions of theMotor and Sensory Cortex

  12. Areas of the Cortexin Four Mammals

  13. Association Areas What can be inferred about organisms with largerassociation areas?

  14. Review • Describe the functions of the following parts of the Cerebral Cortex: • Frontal Lobes • Parietal Lobes • Occipital Lobes • Temporal Lobes • Motor Cortex • Sensory Cortex • Association Areas

  15. Homework • Unit 3 Key People: • Research Study Response #1:“One Brain or Two?” (Pgs. 1-11) • Unit 3 Project:“3-D Brain Model”
