Three experiments using rapid serial visual presentation (RSVP) tested participants' ability to detect targets in streams that are in motion. These experiments compared the ability to identify moving versus stationary RSVP targets and examined the attentional blink with pairs of targets that were moving or stationary. One condition presented RSVP streams in the center of the screen; a second co...

In 1932 Adie1 described a syndrome in which unilateral accommodation and pupillary contraction were abnormal. It typically was observed in young women with no history or evidence of syphilis and involved a unilateral dilated pupil that was unresponsive to light. He noted that deep tendon reflexes were absent or markedly diminished in these patients. He concluded that it was "a benign disorder s...

An 8-year-old girl presented with opsoclonus-like eye movement and an 18 month history of intermittent facial tics. Investigations were all normal. Electro-oculography showed the eye movements to be of variable amplitude (10-40 degrees), with no intersaccadic interval, and with a frequency of 3-4 Hz. Saccades, smooth pursuit, optokinetic, and vestibular reflexes were all normal. These abnormal ...

The Fate of Hypertensive Patients with Clinically Proven Spontaneous Intracerebral Hematomas Treated Without Intracranial Surgery • Twenty-five hypertensive patients who had clinically proven intracerebral hematomas, mainly in the internal capsule, were not treated surgically because of stabilization or improvement of their condition or because of extreme brain damage. All of these patients wer...

The neurological findings of 100 patients of adult cerebral malaria were studied. The commonest neurological feature was symmetrical upper motor neuron lesion as evidenced by exaggerated tendon reflexes and bilateral planter extensor (61%). Twenty two percent had features of meningeal irritation and/or meningism. Abnormal posturing occurred decerebrate rigidity (6%) and decorticate rigidity (4%...

Testicular sensation was examined in 32 male diabetics with symptoms suggestive of autonomic neuropathy to evaluate its usefulness as a clinical sign in this condition. Vascular reflex responses to the Valsalva manoeuvre and sustained handgrip and blood pressure fall on standing were measured as objective tests of autonomic involvement. Absent or diminished testicular sensation correlated well ...

Damage of the central nervous system often produces an upper motoneuron (UMN) syndrome. Characteristics of the UMS include the presence of positive and negative signs. Positive signs are increased phasic and tonic stretch reflexes, clonus, co-contraction, released flexor reflexes, spastic dystonia, and associated reactions, whereas negative signs signify the loss or impairment of voluntary move...

Assessed 48 infants of HIV-positive and HIV-negative mothers on the Brazelton Neonatal Behavioral Assessment Scale. Infants exposed to HIV-positive mothers were disadvantaged from birth due to their mothers having obstetric complications and to the infants having orienting problems and abnormal reflexes on the Brazelton Newborn Scale. These problems may be early precursors of the later visual-s...

A family with recessively inherited ataxia and dystonic episodes that responded to antiepileptic medication is described. The onset was in the first decade. Clinically the patients have gait and limb ataxia, nystagmus and brisk reflexes, with abnormal visual, auditory and somatosensory evoked responses, but normal nerve conduction velocities and electromyography. Their intelligence is borderlin...
