Unit 3-B (C): The Cerebral Cortex

1
Unit 3-B (C)The Cerebral Cortex

• Mr. McCormick
• A.P. Psychology

2
Do-Now(In Journal)

• Identify the 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 bodys 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 larger association 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
