Reference: Textbook page 73
Spatial summation
occurs when a postsynaptic potential is reinforced by action potentials from the
terminals of several axons reaching the same synapse at more or less the same time.

The occipital lobes are also responsible for combining visual stimuli into meaningful
patterns. Examples of this are the ability to perceive that eyes, a nose and a mouth
make up a recognisable face, or that a group of letters makes a word. In addition, the
integration of sensory experiences takes place in the ocdpital lobes
QUESTION 3
OPTION 3
Reference: Textbook page 74
Noradrenalin (NA)
NA is also called norepinephrine (NE). lt is released by brain cells and sympathetic
nerves as well as the adrenal glands and has an excitatory effect. A lack of NA is
assodated with depression and an excess with mania.
QUESTION 4
OPTION 2
Reference: Textbook page 74-75
Serotonin
Serotonin is found in the brain, digestive tract and blood. Serotonin helps to regulate
the sleep-wake cycle and temperature. lt is also associated with seasonal depression,
a mood disorder that occurs in autumn and winter. Several types of antidepressants
obtain their effect through modulation of serotonin at synapses.
DA is associated with good mental health; however, an excess of dopamine is
believed to be associated with schizophrenia, a mental disorder characterised by
loss of contact with reality. DA is also involved in the control of motor behaviour.
Too little can result in muscle rigidity and tremor. For example, an insufficiency
of DA in the brain contributes to Parkinson's disease, a form of mental disorder
characterised by disturbances of movement and dementia.
