Toward the end of his years at the institute, the first reports of the effects of sensory deprivation appeared and he began his own experiments in this field. These experiments, supported by grants from NIMH, occupied him for the next 10 years during his time at Brooklyn College, Adelphi University, and the research labs at Albert Einstein Medical Center in Philadelphia. This last job was his second interdisciplinary experience working in close collaboration with Harold Persky who added measures of hormonal changes to the sensory deprivation experiments. He collaborated with Persky in studies of hormonal changes during experimentally (hypnotically) induced emotions.
During his time at Einstein, he established relationships with other principal investigators in the area of sensory depr
