Molecular trigger for Huntington's disease found

...ors include abnormal reflexes such as an inhibited startle response to loud noise, which is also present in human HD patients. "In summary, our study establishes a specific role for p53 in HD," concluded Sawa and colleagues. "As p53 is a nuclear transcription factor that regulates various mitochondrial gene...

Whiplash injuries ?are they caused by startle reflexes?

...uggests that a cause of whiplash injuries could be startle reflexes elicited by unexpected loud sounds. Whiplash injuries most commonly result from seemingly minor low-speed rear-end collisions. The reason for the injury is not known but it is generally thought that the sudden acceleration of the body rela...

Zinc plays important role in brain circuitry

...ed transmission of visual signals, and an enhanced startle response to sudden noise. Electrophysiological studies of the mutant animals' brain and spinal neurons showed significant zinc-related abnormalities in transmission of signals at the connections, called synapses, among neurons. Betz and his col...

The great escape -- fleeing fish fall in line

...ponses within a school is maintained in successive startle events. Head of the research group Dr Paolo Domenici stated, “Our work is the first to show that fish maintained under the same conditions, with no differential treatment, show a tendency for keeping a relatively fixed chronological order of esca...
