Is 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.

Show is a picture of a developing neural tube, what structure in the developed brain with occur from the central 'hole' within the neural tube?

1

In what type of division are Neuroepithelial (NE) cells said to divide?

1

What is an outcome of a person who has not had the correct amount of Neuroepithelial divisions during neuronal development?

1

What is the name given to the 'initial' non differentiated cell within the nervous system?

1

Tick all the box that correspond to a name of morphogen found within the brain during development

1

Is 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.

1

In what area of the brain is Sonic Hedgehog found?

1

What morphogens would you find in the dorsal region of a developing brain?

1

Is this statement true?
The brain forms youngest cells on the inside and the oldest cells on the outside.

1

Heterotopia 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?

1

What morphogen is key in forming the layering system found within the cerebral cortex?

1

Is 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.

1

Synaptogenesis occurs when the filapodia reach the right location, What adhesion molecules stablise the contact between filopodia and passing axons?

1

What will happen if the filopodia reaches an axon that is not complimentary?

1

During synapses strengthening if the circuit is effective what receptor is activated and what does it allow to move into the cell?

1

Calcium ions moving into the axon allows what to happen?

1

Is this statement true?
people born with ipsilateral sensory and motor pathways will have severe sensory and motor deficits.

1

In what direction do Afferent neurones (Sensory neurones) carry information?

1

How does the central sulcus of the cortex divide function?

1

What region of the brain controls personality and behaviour?

1

What is the name of the pathway that is in control of motor functions of the body?

1

Is this statement true?
The thalamus is the 'gateway' to the cerebral cortex

1

what region of the cerebral cortex does the anterior nuclear group of the thalamus signal too?

1

What part of the cerebral cortex does the mediodorsal nuclear group relay too?

1

What area of the cortex do the medial and lateral geniculate bodies relay to? (Respectively)

1

What is the name of the part of the brain that is linked with dopamine release and therefore has been linked to Parkinson's disease?

1

What are the parts of the brain stem?

1

In which part of the brain stem does 80% of the cortico-spinal tract decussate?

1

is this statement true?
The corticospinal tract is particularly associated with finely-fractioned voluntary movements (e.g. control of the hands)

1

In what part of the internal capsule do the efferent fibres of the cortico-spinal tract pass through?

1

is this statement true?
The majority of the anterior corticospinal tract do not decussate?

1

Is this statement true?
A lesion affecting the posterior limb of the right internal capsule will cause paralysis on the right side of the body.

1

Is this statement true?
Cortico-bulbar tract, controls motor fibres that control the activitity of motor neurones located in the cranial nerve nuclei of the brainstem.

1

What two nerves are being tested when testing a patients GAG reflex?

1

Which of these is a key feature of a first-order neurone?

1

Which of these is a key feature of a second order neurone?

1

What is the dorsal column pathway mainly responsible for?

1

What two receptors are linked to the spino-thalamic pathway?

1

Compression of the ventral root will cause what types of symptoms?
