Our mission: To provide free and repetitive opportunities to hone neurosurgical skills that are directly transferrable to theatre.

KNL co-lead and TPD Mr @AhilanKVasan speaking at the #Kings30 meeting on the @KingsNeuro way and the importance of training future neurovascular surgeons

@KingsNeuroLab @OCTWW @JungJosephine @NidaKalyal @sebmigueltoescu @hugo_lh @M_El_Sheikh @jon_funnell @KingsNeuro Excellent day with engaged trainees from the London rotation and also as far afield as Scotland and Liverpool. Plenty of chat today about how much condyle is enough #ifyouknowyouknow - no doubt one piece vs two piece will generate the same debate in May.

Another great day in the mock OR for the third installment of KNL, focusing on the Far Lateral approach, with great weather welcoming our delegates from near and far! Next installment - the OZ...

2 Petrous part of ICA 3 Superior semicircular canal corresponds to the arcuate eminence, a landmark used to help identify the porus acoustics during the middle temporal approach for intracanalicular VS.

Facial nerve parasympathetic supply to the submandibular gland is via the chorda tympani which merges with the lingual nerve to synapse in the submandibular ganglion. Parasympathetic supply to the parotid travels with the glossopharyngeal nerve via the otic ganglion.

The GSPN leaves the skull via the foramen lacerum but unites with the deep petrosal nerve and passes through the vidian canal to synapse on the pterygopalatine ganglion.

ANSWERS 1 Greater superficial petrosal nerve, branch of the facial nerve that carries preganglionic parasympathetic fibres that are secretomotor to the lacrimal and mucosal glands of the nasopharynx and soft palate.

Quiz 4 1What is the structure highlighted in yellow, how does it leave the cranium and what is its function? 2Which segment of which blood vessel is underlying it? 3What is the structure marked with the number 1 and its bony landmark

This is a different eponymous stroke syndrome to Dejerine-Roussy which describes a contralateral hemibody pain syndrome developing after unilateral thalamic injury.

This the continuation of the ascending dorsal column which crosses after synapsing with second order neurones in the nuclei cuneatus and gracili.

3. Dejerine syndrome (medial medullary syndrome), may also include contralateral loss of proprioception and two point discrimination due to involvement of the medial lemniscus.

e.g. exaggerated jaw jerk reflex. Infranuclear lesions may demonstrate fasciculations and hemi wasting of tongue

2. The tongue will point towards the side of weakness. Supranuclear lesions point away from lesion due to crossed descending motor control, infranuclear point towards. Supranuclear lesions may also be associated with spasticity and include other signs of pseudobulbar palsy

ANSWERS-3: 1. Hypoglossal nerve, hypoglossal nucleus in medulla. Found deep to hypoglossal trigone,  inferior to the stria medullaris and medial to vagal trigone in floor of fourth.

3What is the name of the clinical syndrome in which a nuclear/infranuclear lesion to this nerve is accompanied by contralateral hemiplegia and hemisensory loss?

Neuroanatomy quiz 3 1What is the yellow structures and where does it originate? 2How does a supranuclear lesion affecting it manifest and how is this different from a nuclear/infranuclear lesion?

4.      Optic radiation, contalateral  homonymous hemianopia

We are very excited to announce that we have found our new permanent home in the mock OR in KCL's SIE, with an exciting programme of free human tissue dissection courses. Please see details here:

Bilateral LGB lesions can result in hourglass field defects, typically this can result from extrapontine myelinolysis because of rapid overcorrection of hyponatraemia.
