the interhemispheric transfer ( iht ) of such lateralized engrams is more efficient when the untrained eye rather than the trained eye is used during interdepression training ( 10 trials ) preceding the retention test with the contralateral hemisphere , probably because the untrained hemisphere is indispensable for readout in the first case ( imperative iht ) but can be completely bypassed in the second case ( facultative iht ) .
