46.1
How Is the Mammalian Nervous System
Organized? 985
A functional organization of the nervous
system is based on flow and type of
information 985
The vertebrate CNS develops from the
embryonic neural tube 986
The spinal cord transmits and processes
information 987
The reticular system alerts the forebrain
988
The core of the forebrain controls
physiological drives, instincts, and
emotions 988
Regions of the telencephalon interact
to produce consciousness and control
behavior 989
46.2 How Is Information Processed
by Neuronal Networks? 992
The autonomic nervous system controls
involuntary physiological functions
992
Patterns of light falling on the retina
are integrated by the visual cortex
992
Cortical cells receive input from
both eyes 996
46.3
Can Higher Functions Be Understood
in Cellular Terms? 997
Sleep and dreaming are reflected in
electrical patterns in the cerebral
cortex 997
Some learning and memory can be localized
to specific brain areas 999
Language abilities are localized in
the left cerebral hemisphere 1000
What is consciousness? 1001
