Which of the following Internal midbrain nuclei receives ascending bilateral input from the auditory relay nuclei of the medulla (cochlear nuclei) and pons (superior olivary nucleus) through the lateral lemniscus?
Superior Colliculus
Inferior Colliculus
Periaqueductal Gray (PAG)
Substantia nigra
Red nucleus
The medial longitudinal fasciculus.....
Interconnects motor nuclei of CN III, IV, and VI to coordinate function of the extraocular muscles
Sends auditory input to the inferior colliculus
Facilitates the discharge of flexor muscles
Helps regulate voluntary movement by projecting dopaminergic fibers to the neostriatum
The superior colliculus does all these things EXCEPT
Mediate audio visual reflexes
Tracking of movement of objects in visual fields (horizontal conjugate gaze)
Project to the tectospinal tract to produce reflex movements of the head and neck
Modulation of pain impulses
The Periaqueductal Gray (PAG) does all of these things EXCEPT
Regulation of autonomic functions
Discharge flexor muscle neurons
Regulation of affective and emotional processes
Modulation of pain impulses

Locus Ceruleus
Dorsal Tegmental nucleus
Mesencephalic nucleus
Dorsal nucleus of Raphe
Damage to the dopaminergic fibers of which internal midbrain nuclei causes Parkinson's disease?
Superior colliculus
Red Nucleus
Periaqueductal Gray (PAG)
Substancia Nigra
Which Periaqueductal Gray nuclear group contains serotonergic neurons?
Locus Ceruleus
Dorsal Tegmental nucleus
Mesencephalic nucleus
Dorsal nucleus of Raphe
Which internal midbrain nucleus projects GABAnergic fibers to the thalamus and dopaminergic fibers to the neostriatum (caudate + putamen)?
Periaqueductal Gray
Red nucleus
Superior Colliculus
Substantia nigra
Which Periaqueductal Gray nuclear group contains noradrenergic neurons?
Locus Ceruleus
Dorsal Tegmental nucleus
Mesencephalic nucleus
Dorsal nucleus of Raphe

Occlusion of PICA
Contralateral hemiplegia, ipsilateral paralysis of eye movements, and contralateral ataxia are all symptoms of....

Benedikt's syndrome
Claude's Syndrome
Parinaud syndrome
The difference between Claude and Weber syndrome is?
Only in Claude syndrome is the paramedian branches of the posterior cerebral artery occluded
Claude syndrome has ipsilateral paresis of the eyes while Weber syndrome does not
Claude syndrome injures the corticospinal tract while weber does not
A patient with claude syndrome will not have contralateral hemiplegia but will have contralateral ataxia
