Abstract The efferent projections of the fornix system have been studied in the squirrel monkey using modified silver staining techniques to delineate degenerating fibers and terminal boutons after inducing careful lesions of the subcallosal fornix and dorsal fornix. Subcallosal fornix projections, after supplying the medial and lateral septal nuclei, are traced via precommissural fibers to terminal degeneration in the nucleus of the diagonal band of Broca, nucleus accumbens, gyrus rectus, olfactory ...

The influence of hippocampal electrical stimulation on amygdala extracellular unit activity was studied in the awake squirrel monkey. Hippocampal influence was topographically organized. Stimulation elicited responses in 20% of 476 units tested. Ipsilateral anterior stimulation was more effective than posterior or contralateral stimulation. In the 6 areas with more than 25 tested units, the basomedial nucleus had the highest percentage of responsive units (39%), followed by the accessory basolateral ( ...

✓ Villonodular synovitis is believed to be an inflammatory, proliferative reaction of synovial tissues. The case of a 65-year-old woman with a cervical epidural mass is presented in which histological examination showed that the lesion was villonodular synovitis, an extremely rare occurrence. Because of its cellularity and occasional multinucleated giant cells, villonodular synovitis may be confused with metastatic malignancies or giant-cell tumor of bone.

Differential spread of afterdischarge activity initiated electrically in ventral and dorsal parts of the hippocampal formation was studied by the [14C]deoxyglucose technique in rats. Afterdischarges initiated in either the ventral or dorsal hippocampal formation, without activation of the ventral subicular cortex, increased glucose utilization in the lateral septum. In contrast, afterdischarges initiated by direct activation of the ventral subicular cortex increased glucose utilization in extensive ...

✓ Cerebral amyloid angiopathy (CAA) has been associated with atypical dementia and a variety of other neurological disorders. Intracerebral hemorrhage is the most striking manifestation of CAA. A 63-year-old patient is described who sustained four intracerebral hemorrhages although he had no predisposing factors other than CAA. The neurological and pathological features of CAA are reviewed, with particular emphasis on the problem of CAA-associated intracerebral hemorrhage. On the basis of the experience with ...

abstract In cases of Cushing's syndrome, unusual amounts of fat may accumulate in the spinal epidural space, similar to centripetal fat deposits elsewhere in the body. The mass of excessive epidural fat may be responsible for neurological symptoms referable to compression of the spinal cord or cauda equina. We report three cases illustrating this unusual phenomenon and call attention to three cases reported previously, Although it is an unusual complication of Cushing's syndrome, epidural lipomatosis ...

Cingulate cortex (CC) unit responses to hippocampal volleys and afterdischarges were studied in 4 awake unsedated squirrel monkeys using extracellular microelectrodes. Stimuli were delivered via bipolar electrodes chronically implanted bilaterally in anterior and posterior hippocampus. A total of 412 units in 21 tracks were studied and tested to single and multiple shock stimulation. Spontaneous firing rates were approximately equally distributed among slow (0.25 spikes/s), medium (2.5–10), and fast ( ...

Abstract The common association of occipital neuralgia with post-traumatic cervical arthritis raises the question of whether some cases of occipital neuralgia are due to delayed C-2 or C-3 root entrapment. This hypothesis led to surgical exploration of the C-3 and C-2 roots in a young patient with post-traumatic arthritic occipital neuralgia. The abnormal operative findings and resolution of the neuralgia after C-3 foraminal and C-2 fascial root decompression lead to the tentative proposal that ...

Single neurons of the periaqueductal gray (PAG) were studied during electrical stimulation of the amygdala and hippocampus. Fifty-one percent (34/67) of the units sampled throughout the rostrocaudal extent of the PAG were found to have a limbic influence. PAG neurons were characterized by low spontaneous firing rates (X¯= 4.94 spikes/sec). Units responded to basolateral amygdala stimulation primarily with short duration excitatory responses having a mean latency of 30 ms (range: 13.3–110 ms). Responses ...

The spread of ventral hippocampal afterdischarge activity to nuclei of the basal diencephalon was studied in rats with fornix lesions and combined lesions of the fornix and stria terminalis. The results indicate that a major hippocampal influence on specific hypothalamic, preoptic and basal forebrain structures is conveyed by way of the amygdala's stria terminalis. An additional hippocampal influence on certain basal forebrain nuclei is consistent with projections via the ventral amygdalofugal pathway.

Immunocytochemical methods were used to determine the distribution of cells with cholecystokinin-like immunoreactivity (CCK-LI) in the cat Edinger-Westphal complex (EW). Numerous cells with CCK-LI are found throughout the length of EW. The distribution and frequency of such cells are similar to the pattern of EW neurons that show substance P-like immunoreactivity (SP-LI). Companion retrograde transport experiments reveal that EW neurons which project to spinal cord or the region of the caudal trigeminal ...

✓ Two patients with spontaneous spinal subarachnoid hemorrhage are presented to emphasize the clinical and radiological features of this uncommon illness. Both had severe back pain at the onset. One patient had a subdural hematoma that compressed the conus medullaris and cauda equina, and was drained percutaneously; the other had clots in the subarachnoid space. The cerebrospinal fluid showed a polymorphonuclear pleocytosis that simulated septic meningitis. Complete spinal angiography failed to reveal ...

During radiofrequency (RF) heating of trigeminal rootlets, we regularly measured blood pressure rises to 250 to 300 mm Hg, confirming two previous reports. We also found abnormally increased bleeding times in 12% of 127 patients awaiting operation for trigeminal neuralgia. These two facts probably explain 6 fatalities and 2 lasting hemiplegias from intracranial bleeding unrelated to vascular puncture by the needle electrode during RF procedures for trigeminal neuralgia. We recommend correction of ...
