1Is this statement true?
The definition for synaptogenesis is; the formation of synapses between neurons in the nervous system. Although it occurs throughout a healthy person's lifespan, an explosion of synapse formation occurs during early brain development, known as exuberant synaptogenesis.- AVerdadeiro

- AMicrocephaly

- ASonic hedgehog
- BBMP
- CWNT
- DNeuregulins
- ESemaphorins
- FReelin
7Is this statement true?
Different types of cells found within the brain are programmed to follow different chemical signals, this allows them to move to the correct area of the brain. initiating transcription factors within the cells allowing them to develop into the required cell.- AVerdadeiro
- BFalso
8In what area of the brain is Sonic Hedgehog found?
- AVentral region
- BDorsal Region
- CLateral region
9What morphogens would you find in the dorsal region of a developing brain?
- AWNT

- CReelin
- DSonic Hedgehog
- ESemaphorins
10Is this statement true?
The brain forms youngest cells on the inside and the oldest cells on the outside.- AVerdadeiro
- BFalso
11Heterotopia is an X linked disease, which is only found in females, it is caused by the doublecortin protein which means the person will have double the cortex. What are the symptoms of such a disease?
- ALearning Difficulties
- BSevere Epilepsy
- CStill birth
- DGreater intelligence
12What morphogen is key in forming the layering system found within the cerebral cortex?
- AReelin
- BSonic Hedgehog
- CWNT
- DBMP
13Is this statement true?
Axons, dendrites and migrating neuroblasts rely on a part of their cells called 'filopodia' in order to guide them to the area they need to be.- AVerdadeiro
- BFalso
14Synaptogenesis occurs when the filapodia reach the right location, What adhesion molecules stablise the contact between filopodia and passing axons?
- ABeta-neurexin
- BNeuroligin-1
- CAlpha-neurexin
- DNeuroligin-2
15What will happen if the filopodia reaches an axon that is not complimentary?
- AThe filopodia will retract
- BThe filopodia will still bind, it just won't be active
- Cbinding still occurs and the neuron will still be active.
16During synapses strengthening if the circuit is effective what receptor is activated and what does it allow to move into the cell?
- ANMDA receptor
- BNicotinic receptor
- CCalcium ions
- DPotassium ions
17Calcium ions moving into the axon allows what to happen?
- AIncreases AMPA receptors on the cell surface
- BIncreases the effectiveness of AMPA receptors (phosphorylation)
- CCauses actin cytoskeleton to grow and increase dendritic spine area and thus more space for AMPA receptors
- DStrengthens synpase
- EWeakens synpase
18Is this statement true?
people born with ipsilateral sensory and motor pathways will have severe sensory and motor deficits.- AVerdadeiro
- BFalso
19In what direction do Afferent neurones (Sensory neurones) carry information?
- AFrom the peripheral nervous system to the the CNS
- BFrom the CNS to the peripheral nervous system.
