We studied the effects of aging on modification of the median nerve somatosensory evoked potentials (SEPs) by voluntary movement in 17 aged (66.5 +/- 8.9 years, mean +/- SD) and 12 young normal… Expand
Abnormal baroreceptor-mediated vasopressin release as possible marker in early diagnosis of multiple system atrophy.

- Journal of neurology, neurosurgery, and…
BACKGROUND Although autonomic failure (AF) is a critical symptom of multiple system atrophy (MSA), it may not appear until late in the disease process. OBJECTIVES To clarify whether a detailed… Expand
Effects of glutamic acid relatives on the electrical activity of an identified molluscan giant neurone (achatina fulica férussac)
Effects of glutamic acid and its relatives were examined on the electrical activity of two kinds of neurones (the PON, periodically oscillating neurone, and the TAN, tonically autoactive neurone)… Expand

The present study aimed to elucidate the pharmacological features of GABA receptors on identifiable neurones of Achatina fulica Férussac by testing the effects of GABA analogues, muscimol,… Expand
Pharmacologic characteristics of excitatory gamma-amino-butyric acid (GABA) receptors in a snail neuron.
1. The pharmacologic characteristics of excitatory gamma-aminobutyric acid (GABA) receptors, termed muscimol II type GABA receptors, found in a giant neuron type, v-LCDN (ventral-left cerebral… Expand
Significance of cognitive function in the elicitation of sympathetic skin response in healthy humans.

- Psychology, Medicine
- Journal of the autonomic nervous system
- 6 November 1996
The sympathetic skin response (SSR) is used as an index of sudomotor sympathetic function. However, the central processing of this response is not fully understood. To clarify this point, we assessed… Expand
The validity of a hyperventilation test for an investigation of autonomic failure: assessment in patients with multiple system atrophy and Parkinson's disease
- K. Deguchi, I. Sasaki, +6 authors S. Kuriyama
- International journal of clinical practice
- 27 March 2006
Although heart rate (HR) responses to hyperventilation (HV) have been used as a cardiovascular autonomic function test, autonomic involvement during HV remains uncertain. To clarify the relationship… Expand
Improvement of cardiovascular autonomic dysfunction following anti–copper therapy in Wilson’s disease
Sirs: Detailed autonomic function tests (AFTs) have recently revealed significant abnormalities in almost one-third of patients with Wilson’s disease (WD) [1–4]. However, the time course and… Expand

- Comparative biochemistry and physiology. C…
Abstract 1. A spontaneously firing giant neurone (the TAN, tonically autoactive neurone) sensitive to GABA (inhibition) was identified in the subesophageal ganglia of Achatina fulica Ferussac. The… Expand
