Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
65 participants will be recruited and complete 1 visit at time point 1 (0-2 months), and 2 visits at each timepoints 2-5 with windows of +- 4 weeks (3-6 months, 12 months, 18 months and 24 months). Visits will consist of Magnetic Resonance Imaging (MRI) assessment during the child's natural sleep, Transcranial Magnetic Stimulation (TMS), and Motor Behavioral Assessments.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The first two years of life constitute a critical period of brain development and heightened neuroplasticity. There is now a consensus that, due to brain plasticity and rapid development, providing an early intervention may result in optimal recovery and lower costs of care. Unfortunately, researchers still have only limited understanding of how the brain develops after perinatal stroke and as a result CP diagnoses are typically not made until two years of age. There is an urgent need for very early diagnosis, prognosis and understanding of mechanisms in order to develop novel early interventions to improve outcomes in perinatal stroke with resultant CP.
Integrating study team's experience in studying and caring for this vulnerable infant stroke population, they propose to use non-invasive brain stimulation, neuroimaging, and behavioral assessments to analyze associations between development patterns, especially in the CST, and potential diagnosis of CP.
Specific aims of this study are:
* Aim 1. Map the presence and excitability of corticospinal pathways.
* Aim 2. Map the structural integrity and connectivity of corticospinal pathways.
* Aim 3. Compare motor outcomes from clinical behavioral assessments against corticospinal tract excitability and integrity.
* Aim 4. Identify the association between brain white-matter connectivity and general movements.
* Aim 5. Identify the association between corticospinal circuitry and general movements.
Protocol Amendment approved on 10/22/2021 removes TMS intervention and outcomes, adds a study time point at 0-2 months, and lowers the eligibility age to term.
Protocol Amendment approved on 12/21/2021 adds the TMS intervention back.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Infants
Pre-term and term born infants with corrected gestational age between term age and 24 months with radiologically-confirmed acute unilateral or bilateral brain lesions, including perinatal stroke, neonatal hemorrhagic or thrombotic stroke, involving the motor cortex and/or subcortical structures, and intracranial hemorrhage, involving the motor cortex and/or subcortical white matter, or periventricular leukomalacia. Parents/legal guardians able to attend study visits at the University of Wisconsin-Madison.
Magnetic Resonance Imaging
3 Tesla Discovery MR750 MRI scanner (GE Healthcare, Waukesha, WI) will be used to perform structural imaging, diffusion MRI, relaxometry and microstructural imaging. The exact scan length and parameters of each scan type (T1, T2, DWI) will be set for this study to optimize the quality of data and decrease the length of scanning session for each type of scan. All of the imaging methods have been previously implemented at UW-Madison. Each sequence will take approximately 5-10 minutes.
Behavioral Assessments
The behavioral assessments (GMA: General Movements Assessment; HINE: Hammersmith Infant Neurological Examination; Baby Observation of Selective Control AppRaisal (BabyOSCAR); Bayley-4 / Bayley Scales of Infant and Toddler Development 4th ed; Pediatric Evaluation of Disability Inventory -Computer Adaptive Test (PEDI-CAT)) are infant and age-specific and will be administered by trained pediatric occupational and physical therapists.
Non invasive Transcranial Magnetic Stimulation
TMS will be used to assess cortical excitability and circuitry (not as a neuromodulation intervention). Single-pulse TMS (Magstim 200², Magstim, UK) with a scalp surface coil will be used to assess how the brain is developing and how connected the tract is, between the brain and a target muscle on the arm. 10-20 TMS stimulation pulses will be delivered at a range of stimulation intensities (50-100%) increasing by 5% maximal stimulator output (MSO) at each stage. After this assessment, a brief assessment of peripheral nerve excitability will be performed. Peripheral stimulation will begin at 40% MSO. Stimulation intensity will be adjusted in increments of 5% until motor responses are evident on the EMG. Once motor responses are identified, 10 pulses will be delivered at the stimulation intensity that produced the response. In sum, around 150 stimulation pulses per hemisphere of brain stimulation and 22-60 pulses of peripheral stimulation are expected for TMS assessment of each infant.
