eMags is an engineered photodimerizer pair for optogenetic modulation in mammalian cells that is especially suited for the manipulation of intracellular processes occurring in small volumes or subcellular organelles.
Intentionally preventing the retrieval of an unwanted memory hinders future attempts to reactivate the memory’s neural representation and causes a reduction in the vividness with which it can be recalled.
The brain continues to represent individual fingers in primary somatosensory cortex decades after the amputation of a hand, indicating that cortical maps do not require ongoing sensory input from the body.
The autobiographical memory deficits seen in aphantasia are reflected by altered activation and connectivity patterns of the hippocampus and occipital cortex, corroborating the strong link between memory and mental imagery.
The neonatally maturing pituitary harbors an activated stem cell compartment and shows prominent regenerative capacity, as revealed by single-cell transcriptomic profiling and in vitro (organoid) and in vivo (mouse) exploration.
Neural substrates of objective vs. subjective memory states can be distinguished, including their role in supporting decisions aimed at optimizing performance.

fMRI results show that despite arm amputation, and varying degrees of phantom sensations, canonical hand representation in primary somatosensory cortex is largely maintained.

Combining fMRI with continuous model-based measures of retrieval enables the behavioral and neural dissociation of multiple components of episodic memory.
Physiological evidence shows that the pupillary response to imagined light can be used to index the strength and vividness of an individual’s visual imagery and as a new tool for confirming aphantasia.
