Behaviour of an individual is guided mainly by biological and socio cultural factors.(combination of nature and nurture)
Biological factor include:
ØHeredity,
ØRole
of nervous system,
ØNeurotransmitters
and
ØDifferent
hormones secreted by glands.
These biological factors are very much important in
determining behaviour.
Human beings are biosocial creatures. This is the reason
biology is needed in psychological understanding of organism’s behavior.
ØIt describes behavior and cognition related to biological
process.
ØIt studies neuroscience with the functioning of genes, nervous system, the brain and
endocrine glands.
ØIt describes how neurons function in learning process,thinking,emotions,motivations
etc.
ØIt gives insight to hereditary factors to describe behavior.(eg-twinstudy,intelligence,personality
etc)
ØIt provides insight into the problems of human behaviour having maladjustment symptoms
ØBone

Eg-oHippocampus and Amygdala are involved in formation of new memories.
oImbalance in the neurotransmitters Dopamine and serotonin may underlie mental disturbances like schizophrenia and depression.
Neuron
Cell is the basic unit of living organism.
Neuron- Neuron is a Cell of Nervous system or,
It is the Basic Unit of Nervous System
Nervous System- It consists of all
the Nerves in our Body, together with our Brain and Spinal Cord.
The human body is composed of
different types of Cells like
ØBone
cells,
ØMuscle
cells,
ØBlood
cellsØBody
cells ,ØNerve
Cell etc..
“All neurons are
Cells but all cells are not Neurons”
Each type consists millions of tiny
cells, and forms a single unit which has a specialized function.
“The duty of carrying Electrical Messages from one part of
the body to the other has been assigned to Nerve Cells/Neuron.”
Neuron
ØNeuron is the basic unit of Nervous system . A nerve cell with
all its branches is called a Neuron.
ØNeuron is defined as the structural and functional unit of
Nervous system that process and transmits information of nervous system .It is otherwise
called as Nerve cell.
ØNeuron is like any other cell in the body
having nucleus .
ØThe duty of carrying Electrical Messages from
one part of the body to other has been assigned to neuron.
Types
of Neuron according to their function.
1.Motor Neuron
2.Sensory Neuron 3.Inter Neuron
Functions
of Neurons
vReceiving the information – Neuron Receives the changes that
occurs around
the environment of an organism.
vProcessing the information – Finally,
Coordinate to adapt to that Changed Situation.
vTransmitting the information – It Circulates the
changed information all over the body.
