The neurophenomenology research program, pioneered by Varela (1996), rigorously examines subjective experience using first-person methodologies, inspired by phenomenology and contemplative practices. This review explores recent advancements in neurophenomenological approaches, particularly their application to meditation practices and potential clinical research translations. We first examine innovative multi-dimensional phenomenological assessment tools designed to capture subtle, dynamic shifts in experiential contents and structures of consciousness during meditation. These experience sampling approaches allow shedding new light on the mechanisms and dynamic trajectories of meditation practice and retreat. Secondly, we highlight how empirical studies in neurophenomenology leverage the expertise of experienced meditators to deconstruct aversive and self-related processes, providing detailed first-person reports that guide researchers in identifying novel behavioral and neurodynamic markers associated with pain regulation, self-dissolution and acceptance of mortality. Finally, we discuss a recent framework, deep computational neurophenomenology, which updates the theoretical ambitions of neurophenomenology to \"naturalize phenomenology\" (Varela, 1997). This framework uses the formalism of deep parametric active inference, where parametric depth refers to a property of generative models that can form beliefs about the parameters of their own modeling process. Collectively, these methodological innovations, centered around rigorous first-person investigation, highlight the potential of epistemologically beneficial mutual constraints among phenomenological, computational, and neurophysiological domains.
