Cross-modal plasticity in children with cochlear implant: converging evidence from EEG and functional near-infrared spectroscopy

Author(s): Deroche MLD; Wolfe J; Neumann S; Manning J; Hanna L; Towler W; Wilson C; Bien AG; Miller S; Schafer E; Gemignani J; Alemi R; Muthuraman M; Koirala N; Gracco VL;

Over the first years of life, the brain undergoes substantial organization in response to environmental stimulation. In a silent world, it may promote vision by (i) recruiting resources from the auditory cortex and (ii) making the visual cortex more efficient. It is unclear when such changes occu ...

Audiovisual integration in children with cochlear implants revealed through EEG and fNIRS

Author(s): Alemi R; Wolfe J; Neumann S; Manning J; Towler W; Koirala N; Gracco VL; Deroche M;

Sensory deprivation can offset the balance of audio versus visual information in multimodal processing. Such a phenomenon could persist for children born deaf, even after they receive cochlear implants (CIs), and could potentially explain why one modality is given priority over the other. Here, we recorded cortical responses to a single speaker uttering t ...

Motor Processing in Children With Cochlear Implants as Assessed by Functional Near-Infrared Spectroscopy

Author(s): Alemi R; Wolfe J; Neumann S; Manning J; Hanna L; Towler W; Wilson C; Bien A; Miller S; Schafer E; Gemignani J; Koirala N; Gracco VL; Deroche M;

Auditory-motor and visual-motor networks are often coupled in daily activities, such as when listening to music and dancing; but these networks are known to be highly malleable as a function of sensory input. Thus, congenital deafness may modify neural activities within the connections between th ...

Dynamic networks differentiate the language ability of children with cochlear implants

Author(s): Koirala N; Deroche MLD; Wolfe J; Neumann S; Bien AG; Doan D; Goldbeck M; Muthuraman M; Gracco VL;

Background: Cochlear implantation (CI) in prelingually deafened children has been shown to be an effective intervention for developing language and reading skill. However, there is a substantial proportion of the children receiving CI who struggle with language and reading. The current study-one ...

Auditory evoked response to an oddball paradigm in children wearing cochlear implants

Author(s): Deroche MLD; Wolfe J; Neumann S; Manning J; Towler W; Alemi R; Bien AG; Koirala N; Hanna L; Henry L; Gracco VL;

Objective: Although children with cochlear implants (CI) achieve remarkable success with their device, considerable variability remains in individual outcomes. Here, we explored whether auditory evoked potentials recorded during an oddball paradigm could provide useful markers of auditory process ...

Structural brain network topological alterations in stuttering adults

Author(s): Gracco VL; Sares AG; Koirala N;

Persistent developmental stuttering is a speech disorder that primarily affects normal speech fluency but encompasses a complex set of symptoms ranging from reduced sensorimotor integration to socioemotional challenges. Here, we investigated the whole-brain structural connectome and its topological alterations in adults who stutter. Diffusion-weighted ima ...
