Ultrasound Images of the Tongue: A Tutorial for Assessment and Remediation of Speech Sound Errors

Ultrasound Images of the Tongue: A Tutorial for Assessment and Remediation of Speech Sound Errors

Ultrasound imaging can be used to display the shape and movements of the tongue in real time during speech. The images can be used to determine the nature of speech sound errors. Visual feedback of the tongue can be used to facilitate improvements in speech sound production in clinical populations.

Historical Cost Principle

Historical Cost Principle

The Historical Cost Principle is a fundamental accounting concept that requires businesses to record assets at their original purchase price. This principle ensures that the value of assets is based on actual transactions, making financial records objective and verifiable. Since documents like invoices or contracts support the recorded cost, they provide a clear and consistent basis for maintaining accounts over time.This principle is especially important for creating reliable and stable...

Study Design for Navigated Repetitive Transcranial Magnetic Stimulation for Speech Cortical Mapping

Study Design for Navigated Repetitive Transcranial Magnetic Stimulation for Speech Cortical Mapping

Navigated repetitive transcranial magnetic stimulation is a highly efficient non-invasive tool for mapping speech-related cortical areas. It helps in designing brain surgery and speeds up the direct cortical stimulation conducted during the surgery. This report describes how to perform speech cortical mapping reliably for preoperative evaluation and research.

Designing Automated, High-throughput, Continuous Cell Growth Experiments Using eVOLVER

Designing Automated, High-throughput, Continuous Cell Growth Experiments Using eVOLVER

The eVOLVER framework enables high-throughput continuous microbial culture with high resolution and dynamic control over experimental parameters. This protocol demonstrates how to apply the system to conduct a complex fitness experiment, guiding users on programming automated control over many individual cultures, measuring, collecting, and interacting with experimental data in...

Quantitative Analysis by Thermogravimetry-Mass Spectrum Analysis for Reactions with Evolved Gases

Quantitative Analysis by Thermogravimetry-Mass Spectrum Analysis for Reactions with Evolved Gases

Precise determination of the evolved gases' flow rate is key to study the details of reactions. We provide a novel quantitative analysis method of equivalent characteristic spectrum analysis for thermogravimetry-mass spectrum analysis by establishing the calibration system of the characteristic spectrum and relative sensitivity, for obtaining the flow...

Background:

The origins of speech and language are central to understanding human cognition.
The 'cognitive revolution' revived interest in the evolution of language.

Observation:

The study revisits the long-standing debate on language evolution.
It examines the interplay between cognitive capacities and linguistic development.

Findings:

Early cognitive abilities likely played a crucial role in the emergence of speech.
Language evolution is intrinsically linked to the development of the human mind.

Implications:

Understanding language evolution offers insights into human cognitive history.
This research informs theories on the biological basis of language.
