Abstract
The influence of prenatal malnutrition on the reactivity of the rat parietal association cortex was studied by testing thresholds of direct cortical responses.
Chronic and acute prenatal starvation caused a significant increase of cortical chronaxie values, indicating a detrimental effect on the axodendritic synapses.
Since these synapses subserve cortico-cortical influxes underlying association processes, this detrimental effect could be correlated with behavioral and learning deficits found in malnutrition.
