The engaging, applying, exercising, realising, and practising of ideas
Inhibition of inappropriate behaviour is controlled by what area of the brain?
What are some symptoms of Frontal Lobe dementia?
- Disinhibited behaviour
- Bladder dysfunction
- Gait apraxia (magnetic gait)
Saccadic movements are controlled by what?
Frontal lobe / Frontal eye fields
Where are the legs of a human tropographically represented on the cerebrum?
Medial aspect of the brain
Where is the face / arms of a human topographically represented on the cerebrum?
Lateral aspect of the brain
What is an Upper Motor Neuron defined as?
Neurons above the level of the anterior horn cells
What is a Lower Motor Neuron defined as?
Neurons below the level of the anterior horn cells
Give examples of symptoms of a LMN lesion
- Babinski -ve
Give examples of symptoms of a UMN lesion
- Babinski +ve
What is the name for the Descending motor neuron tract? How many neurones does this pathway have?
Corticospinal Tract, 2
A lesion in the right motor cortex will cause what motor symptoms?
Left sided (contralateral) upper motor neuron weakness
A lesion in the right cranial nerve nuclei will cause what motor symptoms?
Right sided (ipsilateral) lower motor neuron weakness
A lesion in the right side of the spinal cord will cause what motor symptoms?
Right sided (ipsilateral) Upper Motor Neuron weakness
Is above anterior horn cell, so UMN
A stroke affecting the Left middle cerebral artery will cause what motor symptoms?
Right sided (contralateral) Upper Motor Neuron weakness
A lesion in the right parietal cortex, internal capsule or thalamus will give rise to what sensory symptoms?
Left sided (contralateral) sensory deficit
A lesion in the left half of the spinal cord will give rise to what sensory symptoms?
Right sided (contralateral) sensory anterior column loss below level of lesion and left sided (ipsilateral) posterior column loss
Anterior column = decussates
Posterior column = does not decussate
Are Cranial nerves UMN or LMNs?
Cerebellar lesions cause what sided lesions?
Ipsilateral (same side)
What are 7 features of Cerebellar dysfunction?
I: Intention Tremor
S: Slurred Staccato
If there was an Oculomotor (CN III) lesion, what would you see in a patient?
- Eyes are down and out
- Dilated pupil (parasympathetic nerve)
What is Horner's Syndrome caused by?
Sympathetic nerve supply is damaged
How is Horner's Syndrome characterised?
- Anhidrosis (reduced sweating)
- Miosis (constriction)
