2014
Three-dimensional (3D) microstructured composite beams are fabricated through the directed and localized infiltration of nanocomposites into 3D porous microfluidic networks. The flexibility of this manufacturing method enables the utilization of different thermosetting materials and nanofillers in order to achieve a variety of functional 3D reinforced nanocomposite macroscopic products.

The Transwell Migration Assay

Cells migration in response to chemical cues is crucial to development, immunity and disease states such as cancer. To quantify cell migration, a simple assay was developed in 1961 by Dr. Stephen Boyden, which is now known as the transwell migration assay or Boyden chamber assay. This set-up consists an insert which separates the wells of a multiwell plate into top and bottom compartments. Cells whose migration is to be studied are seeded into the top compartment and the chemoattractant...

Memory Development: Demonstrating How Repeated Questioning Leads to False Memories

2023
Source: Laboratories of Judith Danovitch and Nicholaus Noles—University of Louisville A person is defined as a unique individual based on the people and events they encounter in their lives. Thus, creating, storing, and recalling memories are essential elements of the human experience. However, memory, as adults experience it, takes time to develop. Although young children can learn facts and remember details of their lives from moment-to-moment and day-to-day, they do not create...

His approach linked a first-person report to an observable event. Trained dreamers used prearranged eye movements to mark the moment they recognized the dream state, while polysomnography recorded sleep-related brain and body activity. That correspondence gave researchers a way to examine conscious awareness during sleep without treating the dreamer’s report as the only evidence.
Rather than relying solely on a person’s description after awakening, the research used an agreed-upon signal delivered during the dream. If that signal appeared in the recorded sleep data, investigators could relate reported awareness to an event occurring while sleep continued. This helped separate lucid-dream reports from ordinary dream reports under controlled conditions.
REM sleep supplies the physiological context in which lucid dreaming is typically observed. By identifying the sleep period alongside the dreamer’s signal, researchers can study awareness as part of an ongoing sleep state rather than as a waking recollection alone. This makes lucid dreaming useful for examining how consciousness, subjective experience, and bodily activity relate.
In a laboratory design, a trained dreamer sleeps while polysomnography records relevant brain and body activity. Before sleep, the researcher and participant establish an eye-movement signal for recognizing the dream state. During the night, the signal can be compared with the recording, creating a controlled link between the participant’s experience and measured sleep data.
Researchers can use this framework to investigate more than whether lucid dreaming occurs. LaBerge’s work supports questions about consciousness, memory, imagination, and nightmare management, because the dreamer can identify awareness while the experience is underway. The method therefore connects psychological topics that are usually reported retrospectively with observations collected during sleep.
Its lasting importance lies in treating subjective experience as compatible with controlled measurement. Lucid-dream studies do not replace the dreamer’s report; they pair it with a prearranged behavioral signal and polysomnographic record. That combination offers psychology a research model for studying consciousness by comparing what a person experiences with measurable activity during sleep.
