Longitudinal analysis of regional grey matter loss in Huntington disease: effects of the length of the expanded CAG repeat.

 · 1970

BACKGROUND: The mechanisms guiding the progression of neuronal damage in patients with Huntington disease (HD) are not completely understood. It is unclear whether the genotype--that is, the length of…

Effects of temperature on the decline in miniature end-plate potential frequency following a tetanus.

 · 1970

When frog nerve-muscle preparations are stimulated tetanically in saline solutions containing Ca2+, Mn2+, Co2+, or Ni2+ there is a substantial rise in miniature end-plate potential (MEPP) frequency. A…

What noseleaves do for FM bats depends on their degree of sensorial specialization.

 · 1970

BACKGROUND: Many bats vocalizing through their nose carry a prominent noseleaf that is involved in shaping the emission beam of these animals. To our knowledge, the exact role of these appendages has …

Stimulation-dependent release of adenosine triphosphate from hippocampal slices.

 · 1970

Schaffer collaterals of rat and mouse hippocampal slices were stimulated with bursts of pulses (300 Hz for 50 ms, 2-s intervals) for 30-s which caused a stable increase in the size of the population s…
