The Neuroscience of Human Behavior: A
Comprehensive Study Guide on the Nervous System in
Psychology
Prepared by: Andy Masis & Professional RMG-Net Team
INTRODUCTION
These study notes on "Biological foundations of behavior and the nervous system" as a Topic in
General Psychology will be helpful to students who are studying for exams as they provide a
comprehensive overview of the key concepts and principles in this area of study. The notes
cover important terminologies, multiple-choice questions, essay questions, and their respective
answers. The notes are also presented in a clear and concise manner, making it easier for
students to understand and remember the information.
For new students who are just joining, these study notes will provide a solid foundation for
their understanding of the biological foundations of behavior and the nervous system. They will
help new students catch up with the rest of the class and provide them with a clear
understanding of the material that will be covered throughout the course.

,The study notes are also important for lecturers as they can serve as a useful teaching aid.
Lecturers can use these notes to supplement their lectures, and provide their students with
additional resources that will help them understand the material. Additionally, scholars can also
benefit from these notes as they provide a concise and clear summary of the key concepts in
this area of study.
In summary, these study notes are an essential resource for anyone studying or teaching the
biological foundations of behavior and the nervous system in psychology. They are beneficial to
students who are studying for exams, new students who are just joining, as well as to lecturers
and scholars in the field. Let's get started!!!
OVERVIEW
The biological foundations of behavior and the nervous system are crucial topics in the field of
psychology. This branch of psychology deals with the biological processes that govern our
behavior and emotions. In this article, we will discuss the basic concepts related to the nervous
system and its functions, as well as the relationship between behavior and the brain.
The Nervous System:
The nervous system is a complex network of cells, tissues, and organs that coordinate and
control the body's functions. It consists of two main parts: the central nervous system (CNS)
and the peripheral nervous system (PNS).
The Central Nervous System:
The CNS consists of the brain and spinal cord. The brain is responsible for regulating all bodily
functions, including movement, sensation, thought, and emotion. It is divided into three main
parts: the hindbrain, midbrain, and forebrain.
The hindbrain controls basic life functions, such as breathing and heart rate. The midbrain is
responsible for regulating sensory information, while the forebrain is responsible for higher-
level cognitive functions, such as memory, learning, and decision-making.

,The Spinal Cord:
The spinal cord is a long, thin, tubular structure that runs from the base of the brain to the
lower back. It is responsible for transmitting information between the brain and the rest of the
body. It also controls reflexes, which are automatic responses to stimuli.
The Peripheral Nervous System:
The PNS consists of all the nerves that lie outside the brain and spinal cord. It is responsible for
carrying information from the body's sensory receptors to the CNS and from the CNS to the
body's muscles and glands.
The PNS is further divided into two branches: the somatic nervous system and the autonomic
nervous system.
The Somatic Nervous System:
The somatic nervous system controls voluntary movements and reflexes. It is responsible for
sending sensory information from the body's sensory receptors to the CNS and for transmitting
motor commands from the CNS to the body's muscles.
The Autonomic Nervous System:
The autonomic nervous system controls involuntary functions, such as heart rate, digestion,
and breathing. It is divided into two branches: the sympathetic nervous system and the
parasympathetic nervous system.
The Sympathetic Nervous System:
The sympathetic nervous system is responsible for the body's "fight or flight" response. It
prepares the body for action by increasing heart rate, dilating the pupils, and increasing
respiration rate.

, The Parasympathetic Nervous System:
The parasympathetic nervous system is responsible for the body's "rest and digest" response. It
slows down the heart rate, constricts the pupils, and decreases respiration rate.
Neurons and Synapses:
Neurons are the basic building blocks of the nervous system. They are specialized cells that
transmit information throughout the body. Each neuron consists of three parts: the cell body,
dendrites, and axon.
The Cell Body:
The cell body is the neuron's control center. It contains the nucleus, which is responsible for
maintaining the cell's functions.
Dendrites:
Dendrites are small, branch-like extensions that receive information from other neurons.
Axon:
The axon is a long, thin extension that transmits information from the cell body to other
neurons.
Synapses:
Synapses are small gaps between neurons where information is transmitted. When an action
potential reaches the end of an axon, it triggers the release of neurotransmitters, which cross
the synapse and bind to receptors on the dendrites of the next neuron.
