NUI Galway has questioned an assertion by the Commission of Investigation into Mother and Baby Homes, about the transfer of infant remains to the university's medical school.
The fifth interim report of the Commission, published in April of last year, stated that the head of the School of Medicine "received and paid for 35 infant anatomical subjects" between 1949 and 1964.
The claim was made in a section of the report referring to the deaths of 86 children from the Tuam Mother and Baby Home at Galway Central Hospital.
Burial records of 50 of these infants had been located and it was thought unlikely they had been used for anatomical studies.
But the commission said no record survived naming the 35 children that appeared to have been given to the School of Medicine.
The revelation led to concerns about the role the university played in the treatment and care of those resident in mother and baby homes.
It resulted in a project to try to identify the children and develop a memorial to them.
But researchers have found that the infants who died in the Central Hospital Galway could not have come from the Tuam institution.
A review of all death certificates for infants under 12 months at the Tuam home, between 1949 and 1965, has found none correspond with the dates linked to the 35 infants.
In addition, they have only found references to the remains of nine infants being provided for medical research, not 35.
It is understood that NUI Galway has informed the commission about its concerns. NUI Galway will publish more information about its research in September.
The commission said the interim report had not made any findings about the 35 infant remains.
In a statement, it said it had simply recorded the fact, adding "the Commission has not suggested that these infants came from the Children's Home, Tuam. We have clearly stated that the children in question cannot be identified as there is no record of their names."
Last month, the Government agreed to a further extension for the completion of the commission's final report. This was due to be published in February, but has been delayed as a result of the Covid-19 pandemic.
The report is now due to be submitted to Government by 30 October.
Investigators say any new information that becomes available in relation to burials or the treatment of anatomical subjects will be included in the commission's final report.
Details about the disputed finding in the interim report came as a new oral history project, detailing the experiences of those who spent time in the Tuam home was launched.
A digital exhibition and podcast series was launched on NUI Galway's website today.
It follows an 18 month project to gather the recollections and experiences of survivors, their families and other interested parties.
The mother and baby home operated in Tuam between the late 1920s and early 1960s.
A number of people who were born, or spent their early years there, are among those who have participated in the oral history project.
