The cells of origin of the dorsolateral (DSTT) and the ventral (VSTT) spinothalamic tracts were studied in 11 monkeys. The spinothalamic tract cells were retrogradely labeled by horseradish peroxidase (HRP) injected in the thalamus. All animals also received a midthoracic spinal cord lesion on the side ipsilateral to the thalamic injections. The distribution of labeled cells found in these anim...

A 62 year old man suddenly presented with a pure left sensory deficit involving only pain and temperature sensations. CT scan and MRI showed a small haemorrhage in the dorsolateral part of the right midbrain. This suggested a lesion limited to the right dorsal spinothalamic tract.

Headache often accompanies intracranial vertebral artery dissection (IVAD), and infrequently, it is the only symptom. Furthermore, IVAD presenting with isolated facial pain is rarer. Ischemia of the spinothalamic tract caused by IVAD is considered as the cause of facial pain. We present a case of intracranial vertebral artery dissection with trigeminal neuralgia-like facial pain which was succe...

BACKGROUND Wallenberg syndrome was first reported by Adolf Wallenberg as arising due to the obstruction of the posterior inferior cerebellar artery (PICA), which caused an infarct in the lateral medulla oblongata (MO). METHOD This study was carried out on brain tissue from 2 patients with typical Wallenberg syndrome and 10 autopsy cases without central nervous system disturbances. RESULTS P...

Many students regard neuroanatomy as a terrifying subject due to the complicated neuronal connections. Purpose of this research was promote easy and logical learning by systematizing rule “three neurons afferent nerves.” The rule, in which second neuron decussates reaches thalamus, applied many structures possible. three are drawn constant pattern intuitively demonstrate rule. could be not ...

We describe the case of a 39-year-old woman with signs and symptoms suggesting cauda equina syndrome. Lumbosacral magnetic resonance imaging (MRI) demonstrated no lesion at this level, while cervical MRI showed a T2-hyperintense lesion in the middle-right anterolateral region of the cervical spinal cord, which may explain the symptoms by involving the anterior spinothalamic tract. We suggest th...
