How the brain prioritizes bodily signals in conscious awareness A new study shows that visual and tactile impressions that are related to our own body are prioritized for reaching conscious awareness. This helps us understand how we develop the feeling that the body is our own—through the brain's integration of what we see and what we feel.

Single enzyme failure found to drive neuron loss in dementia Researchers at Helmholtz Munich, the Technical University of Munich and the LMU University Hospital Munich uncovered a mechanism that protects nerve cells from premature cell death, known as ferroptosis. The study provides the first molecular evidence that ferroptosis can drive neurodegeneration in the human brain. These findings open up new avenues for developing future therapies—particularly for severe early-onset childhood dementia.

Breathe in, breathe out: How respiration shapes remembering First and foremost, we breathe in order to absorb oxygen—but this vital rhythm could also have other functions. Over the past few years, a range of studies have shown that respiration influences neural processes, including the processing of stimuli and memory processes.

Skin-to-brain signal explains why warm hugs make us feel so good about ourselves As winter closes in, you might start to notice your fingers and toes freezing when you go outside, or your face flushing hot when you go into a heated building. In these moments of changing temperature, we become more aware of our bodies.
