The neuron
They are specialised for communication between
other neurons, muscles and organs in the body.
When two neurones connect, this is called a
synaptic transmission.
Synaptic transmission
A synapse is a specialised cell that allows
electrical messages to transfer to an adjacent
neurone. Neurones don't actually touch at the
synapse, electrical impulses jump between cells
at what is called the synaptic cleft.
Too much hormones transmitted by the neurones are called excitatory neurons. If it is too slow then this is called the
inhibitory neurons.
Neurotransmitters are known to have an effect on behaviour and mental processes.
There are three different types of neurons which send certain messages across the body.
Type of neurone Description
Sensory neuron They receive messages from the senses (the external
environment) and send them to the Central Nervous
System- the spine (CNS).
Motor neuron They receive messages from the brain and the spinal
cord and take them to appropriate organs and muscles.
Interconnecting neurons These are found in the eyes, the brain and the spinal
cord. They receive messages from the sensory neurons
and pass messages onto other connecting neurons or
motor neurons.
The diagram shows the process of the neurons performing actions.

Brain stem controls basic (e.g. sleeping and walking) and bodily function (heart rate and breathing).

Cerebral hemispheres coordinate higher functions such as vision and memory.
At the FRONT there is the frontal lobe which is used for motor processing. It involves higher
thought processes such as movement and reasoning.…read more

Scanning techniques
Post mortem: a neurobiological research method in which the brain of a patient with a
disorder/abnormality is examined after death.
+ It can establish cause of death and show abnormalities that may have affected their lfife.
