This article done talks about how children with autism have their "critical period" of language learning affected. Research was done through observation through an EEG which monitored babies of multiple age groups, specifically their auditory cortex.

While this article primarily addresses the phenomenon of dysmusia, difficulty in reading music, it also talks about the cognitive underpinnings of music reading. In the brain, reading music is a widespread, multi-modal activity, meaning that many different areas of the brain are involved at the same time. It includes motor, visual, auditory, audiovisual, somatosensory, parietal and frontal areas in both hemispheres and the cerebellum - making music reading truly a whole brain activity. With training, the neural network strengthens. Even reading a single pitch activates this widespread network in musicians. The article also reiterates a pattern that researchers are finding: while text and music reading share some networks, they are largely independent. The pattern of activation for reading musical symbols and letters is different across the brain. Scientists have determined this via studies of patients with limited brain damage, as brain injury impaired reading of one coding system but spared the other.

Musical training improves the brain's ability to discern the components of sound - the pitch, the timing and the timbre. "To learn to read, you need to have good working memory, the ability to disambiguate speech sounds, make sound-to-meaning connections," said Professor Nina Kraus, director of the Auditory Neuroscience Laboratory at Northwestern University. "Each one of these things really seems to be strengthened with active engagement in playing a musical instrument."

In this article addressed to teachers, author Julia Csillag cites research on the use of wordless texts to teach students with autism spectrum disorder. Wordless texts can be used to address a variety of skills that autistic students typically struggle with, including diverse literacy skills, cognitive flexibility, and nonverbal communication. Removing words and auditory information also supports autistic students since integrating information from multiple senses can take longer in autistic individuals, particularly if this information is linguistic. Removing words can therefore positively influence processing. Using wordless books or movies can build diverse literacy skills in terms of making inferences, understanding narrative structure, and using evidence to support a claim. All wordless "texts" support individuals' ability to make inferences, which is helpful since research shows that "students with Asperger syndrome…had challenges in making inferences from the text" (Knight & Sartrini, 2014). Moreover, researchers have found that "similar processes contribute to comprehension of narratives across different media" (Kendeou, P. et al, 2009), meaning that addressing visual inferences can transfer to inferences made during reading. Images and silent books or movies necessarily require students to infer what is happening, who the characters are, etc.

Researchers have looked into how tonal languages are processed in the brain. They have found that lexical tones are processed in the right hemisphere while consonats are processed in the left hemisphere,

Scientists are reporting in the journal Science that they have identified specialized brain cells that help us understand what a speaker really means. These cells do this by keeping track of changes in the pitch of the voice. "We found that there were groups of neurons that were specialized and dedicated just for the processing of pitch," says Dr. Eddie Chang, a professor of neurological surgery at the University of California, San Francisco. Chang says these neurons allow the brain to detect "the melody of speech," or intonation, while other specialized brain cells identify vowels and consonants. "Intonation is about how we say things," Chang says. "It's important because we can change the meaning, even - without actually changing the words themselves." The identification of specialized cells that track intonation shows just how much importance the human brain assigns to hearing, says Nina Kraus, a neurobiologist who runs the Auditory Neuroscience Laboratory at Northwestern University. "Processing sound is one of the most complex jobs that we ask our brain to do," Kraus says. And it's a skill that some brains learn better than others, she says. Apparently, musicians, according to a study conducted by Kraus, are better than non-musicians at recognizing the subtle tonal changes found in Mandarin Chinese. On the other hand, recognizing intonation is a skill that's often impaired in people with autism, Kraus says. "A typically developing child will process those pitch contours very precisely," Kraus says. "But some kids on the autism spectrum don't. They understand the words you are saying, but they are not understanding how you mean it." The new study suggests that may be because the brain cells that usually keep track of pitch aren't working the way they should.

Teachers can use music to deepen the learning environment in a literacy classroom. Many commonalities exist between music and literacy, especially in the pre-K to second grade years, and therefore music education is a vital element in children's literary development. Here are some areas that reading and music both address: 1. Development of auditory processes 2. Visual decoding processes 3. Vocabulary growth occurs whenever students are exposed to new material, like a story or a song. Putting new information into a musical context can also help student memory. 4. Poetry: vocal music is essentially poetry set to a melody 5. Building confidence in performance, whether it's vocal or instrumental.

When your brain encounters sensory stimuli, such as the scent of your morning coffee or the sound of a honking car, that input gets shuttled to the appropriate brain region for analysis. The coffee aroma goes to the olfactory cortex, while sounds are processed in the auditory cortex. That division of labor suggests that the brain's structure follows a predetermined, genetic blueprint. However, evidence is mounting that brain regions can take over functions they were not genetically destined to perform. In a landmark 1996 study of people blinded early in life, neuroscientists showed that the visual cortex could participate in a nonvisual function - reading Braille. Now, a study from MIT neuroscientists shows that in individuals born blind, parts of the visual cortex are recruited for language processing. The finding suggests that the visual cortex can dramatically change its function - from visual processing to language - and it also appears to overturn the idea that language processing can only occur in highly specialized brain regions that are genetically programmed for language tasks. "Your brain is not a prepackaged kind of thing. It doesn't develop along a fixed trajectory, rather, it's a self-building toolkit. The building process is profoundly influenced by the experiences you have during your development," says Marina Bedny, an MIT postdoctoral associate in the Department of Brain and Cognitive Sciences and lead author of the study, which appears in the Proceedings of the National Academy of Sciences the week of Feb. 28.

A Johns Hopkins study found that damage to a key structure in the brain may explain why some stroke patients can't perceive sarcasm. Researchers looked at 24 people who had experienced a stroke in the right hemispheres of their brains. Those with damage to the right sagittal stratum tended to have trouble recognizing sarcasm, the researchers found. This bundle of neural fibers connects a number of brain regions, including those that process auditory and visual information. Sarcasm can be hard to interpret; it's a complex way to communicate. First, the person has to 1. understand the literal meaning of what someone says 2. detect the components of sarcasm: a wider range of pitch, greater emphatic stress, briefer pauses, lengthened syllables and intensified loudness relative to sincere speech "There're a number of cues people use, and it's both facial cues and tone of voice," noted Dr. Argye Hillis, a professor of neurology at Johns Hopkins University School of Medicine.

Learning a second language is usually difficult and often when we speak it, we cannot disguise our origin or accent. However, there are important differences between individuals with regard to the degree to which a second language is mastered, even for people who have lived in a bilingual environment since childhood. Members of the Cognitive Neuroscience Research Group (GRNC) linked to the Barcelona Science Park, have studied these differences. By comparing people who are able to perceive a second language as if they were native speakers of that language with people who find it very difficult to do so, they have observed that the former group is also better at distinguishing the sounds of their own native language. The study results show that there is a positive correlation between specific speech discrimination abilities and the ability to learn a second language, which means that the individual ability to distinguish the specific phonemes of the language, both in the case of the mother tongue and in the case of other languages, is, without a doubt, a decisive factor in the learning process, and the ability to speak and master other languages."
