Cortical activity for conversational responses in young neurotypical individuals, older neurotypical individuals, and individuals with aphasia: A functional near-infrared spectroscopy study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Functional near-infrared spectroscopy (fNIRS) has the potential for evaluating language and conversational interaction in an ecologically valid way given that participants can be seated and interacting with a conversational partner. Aphasia, an acquired language disorder, impacts language abilities, including conversational interaction. Understanding of cortical activity in people with aphasia for conversational tasks could provide an ecologically valid index of brain function and recovery patterns in this population. This study provides pilot data in the use of fNIRS to evaluate language production for conversational responses in young (adult) neurotypical individuals, adults with post-stroke aphasia, and age-matched (i.e., older) neurotypical adults. Experiment 1 evaluated cortical activity for conversational responses versus sentence repetition in a computer-based conversational question task. Experiment 1 results showed differentiation between experimental conditions (with greater fronto-temporoparietal cortical activity for question answering vs. repetition) in young healthy individuals that was not seen in the people with aphasia and age-matched individuals. Experiment 2 evaluated cortical activity for conversational responses in a structured conversational question task with a live interlocutor versus sentence repetition. Experiment 2 results showed lower cortical activity across regions of interest in the age-matched group and greater cortical activity for question answering versus repetition in bilateral temporal and left parietal regions of interest in the people with aphasia. This study provides preliminary evidence for the potential of fNIRS to characterize cortical activity after stroke for functional language tasks.
