Safety evaluation of a clinical focused ultrasound system for neuronavigation guided blood-brain barrier opening in non-human primates.

Sci Rep 2021 Jul 22;11(1):15043. Epub 2021 Jul 22.

Department of Biomedical Engineering, Columbia University, New York City, NY, 10032, USA.

An emerging approach with potential in improving the treatment of neurodegenerative diseases and brain tumors is the use of focused ultrasound (FUS) to bypass the blood-brain barrier (BBB) in a non-invasive and localized manner. A large body of pre-clinical work has paved the way for the gradual clinical implementation of FUS-induced BBB opening. Even though the safety profile of FUS treatments in rodents has been extensively studied, the histological and behavioral effects of clinically relevant BBB opening in large animals are relatively understudied.

Front Psychiatry 2021 25;12:574482. Epub 2021 Jun 25.

Cumulus Neuroscience Ltd, Belfast, United Kingdom.

Access to affordable, objective and scalable biomarkers of brain function is needed to transform the healthcare burden of neuropsychiatric and neurodegenerative disease. Electroencephalography (EEG) recordings, both resting and in combination with targeted cognitive tasks, have demonstrated utility in tracking disease state and therapy response in a range of conditions from schizophrenia to Alzheimer's disease. But conventional methods of recording this data involve burdensome clinic visits, and behavioural tasks that are not effective in frequent repeated use. Read More

Potential for Behavioural Pressure Modulation at the Upper Oesophageal Sphincter in Healthy Swallowing.

Dysphagia 2021 Jun 16. Epub 2021 Jun 16.

Department of Psychology, Speech and Hearing, University of Canterbury, Private Bag 4800, Christchurch, 8140, New Zealand.

Supratentorial structures are known to be involved in the neural control of swallowing, thus the potential for volitional manipulation of pharyngeal swallowing is of rehabilitative interest. The extent of volitional control of the upper oesophageal sphincter (UOS) during swallowing remains unclear. Prior research has shown that the UOS opening duration can be volitionally prolonged during execution of the Mendelsohn manoeuvre, which does not change the UOS opening time in isolation but the swallowing response in its entirety.

Aversive Conditioning of Spatial Position Sharpens Neural Population-Level Tuning in Visual Cortex and Selectively Alters Alpha-Band Activity.

J Neurosci 2021 Jun 25;41(26):5723-5733. Epub 2021 May 25.

Center for the Study of Emotion and Attention, University of Florida, Gainesville, Florida 32610.

Processing capabilities for many low-level visual features are experientially malleable, aiding sighted organisms in adapting to dynamic environments. Explicit instructions to attend a specific visual field location influence retinotopic visuocortical activity, amplifying responses to stimuli appearing at cued spatial positions. It remains undetermined both how such prioritization affects surrounding nonprioritized locations, and if a given retinotopic spatial position can attain enhanced cortical representation through experience rather than instruction.

Improving vision for surgeons during laparoscopy: the Enhanced Laparoscopic Vision System (ELViS).

Surg Endosc 2021 05 1;35(5):2403-2415. Epub 2021 Mar 1.

TIMC-IMAG Laboratory, Grenoble Alps University, National Centre for Scientific Research, Grenoble National Polytechnical Institute, Grenoble Alps University Hospital, Grenoble, France.

Background: For many abdominal surgical interventions, laparotomy has gradually been replaced by laparoscopy, with numerous benefits for the patient in terms of post-operative recovery. However, during laparoscopy, the endoscope only provides a single viewpoint to the surgeon, leaving numerous blind spots and opening the way to peri-operative adverse events. Alternative camera systems have been proposed, but many lack the requisite resolution/robustness for use during surgery or cannot provide real-time images. Read More
