Main FOCUS on 1. Localization of language process 2. Aphasia 3. Methodology

All this is what NEUROLINGUISTICS is about 1) 3) 2) Neurolinguistics’ cool

A FORMAL definition NEUROLINGUISTICS is the study of the neural mechanisms in the human brain that control the comprehension, production, and acquisition of language.

A MULTIDISCIPLINARY field neuroscience linguistics NEUROLINGUISTICS psychology computer science

LOCALIZATION of language process Where are words? In the left hemisphere Why we know it? Paul Broca

LOCALIZATION of language process (1)Broca’s area speech production. (2)Wernicle’s area speech comprehension (3)Motor Cortex muscular movements. (4)Arcuate fasciculus they connect Wernicke’s and Broca’s areas.

What about the RIGHT hemisphere? Verbal Language + NON- VERBAL LANGUAGE

NON- VERBAL LANGUAGE HOW sth is said The righ hemisphere interprets the emotional connotation of words. Vs Verbal Language WHAT is said The left hemisphere formulates and understands the meaning of words. IMPORTANT for language

An EXAMPLE of a person who has THE RIGHT HEMISPHERE DAMAGE Is Irene a nice person? Yes, she really is a nice girl (in a SARCASTIC tone) He thinks that Irene is nice.

APHASIA • Impairment of language ability. • Developed by injury, a stroke, a brain tumor, inflection or dementia. • Different types of aphasias.

Types of Aphasia • Expressive aphasia (Broca’s aphasia): - Loss of the ability to produce language. - Agrammatism. • Receptive aphasia (Wernicke’s aphasia): - Normal grammar. - Incorrect language content.

Other Types of Aphasia • Transcortical sensory aphasia. • Conduction aphasia. • Anomic aphasia. • Transcortical Motor Aphasia. • Global aphasia. • Mixed transcortical aphasia. • Subcortical aphasia. • Jargon aphasia.

Treatment • No one effective treatment for all types of aphasia. • But treatment in general has positive outcomes by: - Repetition. - Working on task-specific skills. - More recently, computer technology.

METHODS Technology → imaging methods - Hemodynamic methods - oxygen - place - Electrophysiological methods - electronical current - time

Experimental design - Mismatch paradigm ssssssddsssssss - Violation-based *He are talking - Priming nurse/doctor - Stimulation magnetical fields ~ aphasia

PRESS THE BUTTON EACH TIME YOU EAR A CHANGE IN THE TONE It is useful to work in a not consciously manner. It is achieved by involving the subjects in another task, as could be, listening to a tone or music and pressing a button when a change in the tone is observed. Thus, they receive two inputs; the musical in one ear and the speech in the other. Somes investigations show here as the processing of the grammaticals errors happen automatical. music speech
