A recent study suggests that animals can rely on internal expectations about their head movements, rather than vestibular sensations, to see what's in front of them.

Although myxoma is a rare benign tumor, it is the most common benign tumor of the heart. It is predominantly observed in the left atrium (LA). A 38-year-old male patient was admitted to our clinic with exertional dyspnea. Transthoracic echocardiogram revealed a mass in the LA, and transesophageal echocardiogram confirmed a 16x 17-mm sized, spherical-shaped mass in the LA (Fig. 1, Video 1). The ...

Two experiments investigated whether and how clear speech production enhances intelligibility of English fricatives for normal-hearing listeners and listeners with simulated hearing impairment. Babble thresholds were measured for minimal pair distinctions. Clear speech benefited both groups overall; however, for impaired listeners, the clear speech effect held only for sibilant pairs. Correlati...

OBJECTIVE To share with potential authors tips for communicating their ideas more clearly in a scholarly manuscript. DESCRIPTION Communicating scientific, technical, or medical information so that readers can understand its meaning requires logical organization and proper use of language. These 30 tips review basic English grammar and suggest ways authors can clearly and concisely present the...

Combining neuroscience and chemical engineering, researchers at Stanford have developed a process that renders a mouse brain transparent. The postmortem brain remains whole — not sliced or sectioned in any way — with its three-dimensional complexity of fine wiring and molecular structures completely intact and able to be measured and probed at will with visible light and chemicals. The process,...

The resuscitation of a patient in extremis is frequently characterized by chaos and disorganization, and is one of the most stressful situations in medicine. We reviewed selected studies from the fields of anesthesia, emergency medicine and critical care that address the process of responding to a critically ill patient. Individual clinicians can improve their performance by increased exposure ...
