
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:
Structure of the Cerebral Cortex

Cerebral Cortex:
Intricate fabric of interconnected neural cells
covering the cerebral hemispheres
 The body’s ultimate control and informationprocessing center


Glial Cells (Glia):

Cells in the nervous system that support, nourish,
and protect neurons
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)
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
Structure of the Cerebral Cortex
The Visual and Auditory Cortex
The Visual and Auditory Cortex
 Which
lobe is responsible for
interpreting visual information?
 Which
lobe is responsible for
interpreting auditory
information?
f.M.R.I.:
Stimulation of Visual Cortex
Functions of the Cerebral Cortex

Motor Cortex:



Sensory Cortex:



Located at rear of frontal lobes
Controls voluntary movements (Output)
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
Functions of the
Motor and Sensory Cortex
Areas of the Cortex
in Four Mammals
Association Areas
What can be inferred
about organisms with larger
association areas?
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
