SCAsource Snapshot

Snapshot: What is Dysmetria?

Dysmetria is a medical term used to describe a condition that affects one’s ability to control and coordinate their movements accurately. In simpler terms, it is like having a glitch in the brain’s “motion control system”. When someone experiences dysmetria, their movements, such as reaching for an object or touching Read More…

Snapshot: What is Spasticity?

Spasticity is a condition where muscles involuntarily stiffen, impeding normal smooth movements. Spasticity can present in varying severities with varying impacts on daily life. For example, minor spasticity resulting in overly stiff muscles can make precise, dextrous tasks difficult, whereas painful, uncontrollable muscle spasms can cause confinement to bed rest. Read More…

Snapshot: What is Articulation?

Articulation refers to the ability to produce speech sounds using the tongue, lips, jaw, and the roof of your mouth. All of these organs are also known as articulators. The term “articulation” comes from the Latin word “articulatio,” which means “a joint” or “a connection.” In the context of speech Read More…

Snapshot: What is Resonance?

In speech-language pathology, the term resonance refers to nasality in speech. In other words, how nasal a person’s speech sounds. When someone is congested, they likely sound hyponasal, or not nasal enough. This is because the congestion is blocking sound from being resonated in the nasal cavity, or the nose. Read More…

Snapshot: What are Microglia?

The Immune System of the Brain Though the brain is a powerful computational tool, it is also a sensitive and delicate organ. For this reason, it requires specialized protection. This includes the skull, the membranes covering the brain and spinal cord, and the blood-brain barrier (BBB), which is a specialized Read More…

Snapshot: What is the parallel rod floor test?

Disease-relevant research is often first conducted in animal models such as mice. This is done to investigate the underlying disease mechanisms and to test promising treatment strategies before moving into clinical studies. The parallel rod floor test is an assay to measure motor coordination difficulties in mice. In the case Read More…

Snapshot: What is intelligibility?

Speech intelligibility refers to how many words can be correctly understood by a listener. For example, if someone says the phrase, “My name is John,” and a listener hears, “My name is Tom,” then the listener correctly understood 75% of the speech. In a formal speech evaluation, the percentage of Read More…

Snapshot: What is Mass Spectrometry?

Mass spectrometry, also known as “mass spec”, is a very useful analytical tool that is often used in science to determine the masses of different compounds in a sample. Mass spec has a variety of applications but frequently in biological sciences. It is used to determine the identity and abundance Read More…

Snapshot: What is prosody?

Speech not only consists of the words we say, but how we say them. That “how” is what is called prosody: the pitch, loudness, and timing of speech. The term prosody comes from the Greek word prosōidia meaning “song” or “melody.” Therefore, prosody is often viewed as the melody of speech. Read More…
