Biological approach assumptions-
The notion of adaptiveness is based on Darwins responsible for
much of our memory processing as well as auditory information.
The Occipital lobe is concerned with our visual information.
This was stimulated from Brocas findings and the damages he
identified in the 8 patients brain. Which we now know is referred
to as and is associated with speech production.

The third assumption is neurotransmitters. Neurons are
electrically excitable cells that form the basis of the nervous
system. One neutron communicates with another neutron at the
synapse, where the message is relayed by chemical messages. An
example of this is serotonin and a lack of serotonin can result
in depression and a ultimately affecting our mood and sleep.
Neurontransmitters affect our emotions as well as our perception
of others as it was discovered that these individuals that
experienced depression were on antidepressants which worked by
increasing the availability of serotonin at the postsynaptic
receptor site. It was found that high levels of dopamine have
been associated with symptoms of sz.
