Do poor-responder patients benefit from intracytoplasmic morphologically selected sperm injection?
Our results suggest that unselected couples undergoing ICSI that present with poor ovarian response to controlled ovarian stimulation do not benefit from sperm selection under high magnification prior to ICSI.
In addition to confirming cortical involvement, we demonstrate here for the first time a causal relationship between postgap neural activity and perceptual gap detection. Furthermore, our results suggest that gap detection involves an ongoing comparison of pre- and postgap spiking activity. Finally, we propose a simple yet biologically plausible neural circuit that reproduces each of these neural and behavioral results.
