Wearable High-Resolution Haptic Display Using Suction Stimuli to Represent Cutaneous Contact Information on Finger Pad.

A high-resolution haptic display that reproduces tactile distribution information on the contact surface between a finger and an object realizes the presentation of the softness of the object and the magnitude and direction of the applied force. In this article, we developed a 32-channel suction haptic display that can reproduce tactile distribution on fingertips with high resolution. The device is wearable, compact, and lightweight, thanks to the absence of actuators on the finger.

Longitudinal Assessment of Amyloid-β Deposition by [18F]-Flutemetamol PET Imaging Compared With [11C]-PIB Across the Spectrum of Alzheimer's Disease.

This study evaluates the longitudinal changes in the amyloid-β (Aβ) deposition with [18F]-flutemetamol (FMM) PET imaging across the spectrum of Alzheimer's disease (AD), compared with [11C]-Pittsburgh Compound-B (PIB) PET. Eleven AD, 17 mild cognitive impairment (MCI) and 13 cognitively normal (CN) subjects underwent neuropsychological assessment and amyloid PET imaging using [18F]-FMM and [11C]-PIB during a follow-up period. Regions of interest were defined on co-registered MRI, and the FMM and PIB standardized uptake value ratio (SUVR) was used in the same cortical regions.

Food Search Strategy Changes in Caenorhabditis elegans under Chronic Starvation Conditions.

Starvation is a primary threat to survival in nature. This study investigated the effects of starvation on animal behavior and neural function using a nematode model. Nematodes exhibit chemotactic responses to various compounds, including diacetyl produced by food bacteria.

Effect of surgery for cannula implantation into the hypothalamus on the behaviour and neural activity of broiler chicks.

1. The effects of a surgical operation, to implant a guide cannula in the chick hypothalamus for microdialysis, on behavioural responses and neural activity in broiler chicks are described. 2.
