Highlights • Recent infant care experience can alter sensory cortical response to infant calls. • Infant care experience alone is insufficient for long-term salience of calls. • Mom’s physiological state during infant care maintains call salience and plasticity. • Spontaneous firing of call-encoding neurons is selectively suppressed in moms.
