Response preparation is accomplished by gradual accumulation in neural activity until a threshold is reached. In humans, such a preparatory signal, referred to as the lateralized readiness potential, can be observed in the EEG over sensorimotor cortical areas before execution of a voluntary movement. Although well-described for manual movements, less is known about preparatory EEG potentials for saccadic eye movements in humans and nonhuman primates.

Our participatory research team, including autistic adults who use augmentative and alternative communication (AAC) both part- and full-time, designed and administered a 35-question online survey to examine school-based professionals' knowledge, training, and practices related to AAC and autism. The current study reports a portion of the larger data set specific to participants' definitions of speech terms related to autistic speech.

- This study reports on the creation of advanced quantum light sources using electrically controlled semiconductor quantum dots coupled with circular Bragg grating resonators, aimed at enhancing photon emission for quantum technologies.
- The researchers achieved impressive results, including a photon extraction efficiency of up to 30.4% and potential improvements suggesting over 50%, demonstrating significant advancements in the performance of these devices.
- Additionally, they noted high levels of single-photon purity (99.2%) and photon indistinguishability (75%), which are crucial for applications in photonic quantum information systems.
Article Synopsis
- The study investigates how sudden visual distractors influence saccade trajectories, specifically how attention shifts during planned gaze movements can be altered by unexpected stimuli.
- Researchers recorded activity from neurons in the frontal eye field of monkeys to show that the strength of neuron activity correlates with the direction of curvature in saccades, either towards or away from the distractor.
- Findings reveal that neural responses vary based on the distractor’s position and timing, suggesting a complex interplay of attraction and repulsion in saccadic planning, with implications for understanding and diagnosing saccade-related disorders.
Low-dimensional materials, such as MoS, hold promise for use in a host of emerging applications, including flexible, wearable sensors due to their unique electrical, thermal, optical, mechanical, and tribological properties. The implementation of such devices requires an understanding of adhesive phenomena at the interfaces between these materials. Here, we describe combined nanoscale transmission electron microscopy (TEM)/atomic force microscopy (AFM) experiments and simulations measuring the work of adhesion () between self-mated contacts of ultrathin nominally amorphous and nanocrystalline MoS films deposited on Si scanning probe tips.
